Aquarium lighting and choice of lamps, which is better to choose?
Duration of aqua illumination and options to facilitate control
What light is needed for those aquariums in which aquatic plants do not live? In such tanks it is necessary to reduce the intensity of light.
To do this, you can take a lamp of lower power. For containers 30 cm long, the lamp power should not exceed 10 watts. With such lighting, the movement of fish will be visible, and the inhabitants of the artificial home pond will feel comfortable.
When choosing the intensity of illumination, you must consider the breed of fish If albino fish live in an aquarium, then even a level of light would be dangerous for them.
For comfortable illumination in an aquarium with a green flora that does not cause stress in fish, a lamp with a length equal to the length of the aquarium is suitable. This is the best option for selecting lighting for shallow tanks.
For deep tanks, it is better to select a certain compromise that would create comfortable conditions for both flora and fauna. There are several solutions to this problem.
If there is not enough light in the tank for aquatic verdure, then fish species should be chosen from shallow reservoirs that are accustomed to bright light. In this case, the fish will not be dangerous bright light, and it will be useful for plants. You can choose the types of underwater flora that do not need too bright light.
Such varieties are well combined with the content of deep-sea fish. They allow you to create conditions for life, close to natural.
You can pick up seedlings with leaves that can float on the surface of the aquarium and consume the right amount of light. The leaves will create a shade in which the fish will feel comfortable under intense light.
In this case, the arrangement of the aquarium should begin with the cultivation of underwater plants. As soon as comfortable conditions for fish are created in an artificial reservoir, it will be possible to launch them.
Then, in bright light, fish will be able to hide in the grown leaves of algae floating on the surface of the reservoir. Usually the plants grow to the desired size in two months.
For better growth of plants, while there are no fish in the tank, you need to add fertilizer to the soil or water.
When arranging an aquarium, you can pick up high and low species of plants, evenly distributing them in the pond. For starters, choose unpretentious representatives of the aquatic flora: anubiasa, cryptocoryne, elodea, javanese moss, vallysneria, aponogetony, riccia, bacopa, limnofily. You can make such an arrangement only in large aquariums.
For small volume tanks this option is not suitable.
Watch the video about unpretentious aquarium plants.
When setting the illumination, you can adjust the direction to which the light will go. The lamp is best sent to the places of intensive plant growth. So you can equip the backlight in large containers.
Water areas free from aquatic flora should be decorated with snags or stained oak, which will create shaded “islands” that are close to the natural habitats of fish.
Any aquarist will sooner or later have to face the need to purchase additional equipment: it is a question of devices for aeration, filtration, and of lamps that provide the necessary lighting for the aquarium. Let us consider in more detail the main aspects related to this issue.
First of all, it is necessary to clearly understand: the presence of light is very important for the fish that inhabit your aquarium, for the plants in the aquarium, even for bacteria. And if the lighting in the aquarium is insufficient, then first of all you will learn about it from plants.
In such situations, instead of the green color, they acquire a dark brown shade. subsequent processes of decay, which leads to a violation of the biological balance in the aquarium, the development of various harmful organisms and, ultimately, to the death of fish.
As you can see, to ensure proper lighting is extremely necessary. On the modern market are a variety of lamps in the aquarium, which allow to take into account the peculiarities of specific aquarium fish and plants.
Much really depends on the correct lighting of the aquarium. The fact is that the vast majority of plants and fish that can live in an aquarium, come from the tropics. And in these latitudes, the length of daylight is almost 12 hours year-round.
Consequently, it is necessary to arrange the lighting in the aquarium so that the fish live in the conditions of their usual daylight hours.
Is it necessary to organize breaks in the lighting during the day? In fact, there is simply no unequivocal answer to the question of how much light should be switched on.
However, the presence of such interruptions will not play a special role. It is only for convenience that they advise you to turn on the lighting around 10-11 o’clock in the afternoon, which will allow you to enjoy funny games of fish in the aquarium lighting in the same period of time in the evening.
How to correctly determine how exactly the aquarium will be equipped with lighting? As a rule, novice aquarists choose a method of organizing lighting in which the light in the aquarium is provided for a long time.
True, this method is not always combined with the necessary way of life for fish and plants. The second method involves the organization of breaks, as we said above.
Those. This is a method in which the light is interrupted during the day for an hour or two. Finally, the third method is stepped.
The step method (as the name implies) is based on the fact that for a certain period of time the lamps shine at full power. Subsequently, the stepwise method implies a gradual decrease in the light intensity, its complete shutdown and further switching on with a gradual increase in intensity.
For many, the step method is the most acceptable.
In general, it is possible to transfer the functions of switching on-off the lighting throughout the day to the automation. To date, there are very convenient outlets, timers, which allow you to fully automate the management of the lighting process.
The principle of operation of this kind of timers is quite accessible: they are inserted into the outlet and set a specific lighting mode.
How to determine the acceptable intensity of illumination in the aquarium? You can meet with the information that the optimal calculation is 0.5 W per liter of water in the aquarium. However, this calculation can not be called the only true.
The depth of the water, the individual characteristics of the habitat familiar to the fish and the plant, all have an impact on the final calculation of how much power is needed to determine the intensity of the backlight. After all, it is obvious that aquarium inhabitants, accustomed to life at depth, need much less light than residents of shallow water.
It is also quite clear that at a depth of about 20 cm, the intensity of light is greater than at a 60 centimeter depth.
Therefore, the final calculation of the intensity of the light flux in the aquarium can be selected exclusively by a kind of experiment. It is recommended to take as a basis a typical calculation of 0.5 V / l, after which to increase or decrease the intensity.
As a result, you can choose how much is the optimal calculation for your particular case. If the lighting is excessive, the water in the aquarium will begin to bloom, the filament will develop, the walls will be overgrown with algae. With a lack of light, fish will find it difficult to breathe, small-leaved plants will start to die, and the aquarium will be covered with brown spots.
In this case, you may need additional lighting.
When installing lighting in the aquarium, you need to decide on the lamps used. Their types are diverse, but each is characterized by both advantages and disadvantages.
We study this question in more detail.
For a long time, the aquarium was equipped with ordinary incandescent bulbs. Subsequently, they were replaced with energy-saving lamps. However, it should be recognized that providing lighting in an aquarium with such lamps is an outdated option.
The fact is that the use of lamps (including energy-saving) does not give enough light. In addition, these lamps heat too much, which ultimately leads to an imbalance in the heat balance in the aquarium.
The situation is similar when using energy-saving lamps.
Fluorescent lamps can produce good light intensity. However, we have already noted above that it is impossible to provide the light spectrum required by plants with fluorescent lamps.
Modern phytolamps can be a good option. Such illumination should provide optimal light intensity, as well as organize the necessary spectrum.
True, equipping an aquarium with such lamps is not the cheapest pleasure.
LED (LED lighting, ICE) is a new, convenient and perfect way to supply light. The fact is that LEDs are as close to natural sunlight as possible.
When lighting the aquarium through LED lighting ICE is obtained to maintain the stability of the temperature of the water. In addition, the resource at LED significantly exceeds the factory life of other types of lamps.
There are two more positive aspects of using LEDs. First, ICE is the ability to self-adjust the brightness of the lighting.
Secondly, LED provides a variety of lighting colors. As a result of the use of ICE obtained beautiful pictures of underwater life.
As you can see, the lighting of the aquarium is an important stage. Successful solution of this issue depends on the type of lamp chosen and on the characteristics of plants and fish inhabiting the aquarium.
And with the right approach, all aquarium residents should be unusually comfortable.
If you have only fish in the aquarium, for example, African cichlids, and there are no live plants, then everything is simple. You only need light to make you comfortable.
Of course, you should not go too far and put a 1000W arc lamp from a nearby parking lot because the lamp went cheap. Fish too bright lighting no good – it will only cause stress to them and, as a result, illness and other problems – remember the detective stories where the main character is kept alone with a bright lamp on the ceiling around the clock. Usually you will be enough of the lamp, which is included in the kit aquarium.
You can put the lamp with any spectrum. In order to have a more natural color reproduction of fish coloring (and who knows which color is natural?), Put a lamp with a wide spectrum (full-spectrum) or three-phosphate (trichromatic, triphosphate) – not necessarily Triton. Very good lamp GE Chroma-50, which is very inexpensive.
Lamps with a lot of blue light in the spectrum reveal the color of fish due to the “glowing” of fish scales (although is it natural?) – for example, in an aquarium with African cichlids – pseudotrophia, aulonocardia, etc. you can put a lamp with actinic light – the blue color of the fish will look very beautiful. In general, the choice of lamp is determined by your taste and financial capabilities.
For a plant aquarium – It is more difficult. As always, planning first.
Consider the lighting system in advance, so that you don’t have to think about how to place extra lamps or paint over with extra black paint. The planning of the system includes not only a trip to the nearby shops.
Think about what plants you will grow – Javanese fern and Anubias do not require a lot of light, and cabomba will require bright light. You may want to use carbon dioxide and fertilizer to improve plant growth. In this case, you need a lot more light.
Conversely, a bright light, in the absence of fertilizers and carbon dioxide will only lead to the development of algae. It does not make sense to spend all the money on a super-duper lamp and not to think about fertilizers, it does not make sense to install a cylinder with carbon dioxide and put an old lamp.
If you do not have the opportunity to purchase good lamps, then it will be much more difficult for you to grow plants, although it is quite possible – after all, aquarists grew them 50 years ago, when only incandescent lamps were in use.
If you are going to seriously deal with plants, then it makes sense to think about the use of modern lamps – high power (HO, VHO, SHO), metal halide (H /
Metal halide lamps, such as DRI, are practically not made small power (due to problems with arc discharge at low current and low luminous efficiency). It makes sense to put them if you need a power of 300-1000W.
For them, it is necessary to think over the cooling system of the fan, since all the heat emitted by them is concentrated in one place.
If you install expensive lamps – then think about the electronic ballast for them, which is much preferable to conventional ballast.
Use a reflector – a well-designed reflector to increase the efficiency of using lamps. The reflector is effective with compact lamps – if you have 8 T12 lamps in close proximity, then the reflector will not change anything.
Consider in advance the electrical connection scheme, especially if you collect everything yourself. It is impossible to joke with electricity, especially in a humid environment. Be sure to use grounding and fuses that cut off power in the event of a leakage current to an earth wire. Plan how you will do the cover, ventilation, what kind of wires you will use – from the ballast to the lamp there can be a considerable current, many ballasts can not be placed at a considerable distance from the lamp.
The ballast, especially the choke, is very hot, so place it so that it does not heat the lamps, the light output of which decreases with increasing temperature.
LIGHTING FOR AQUARIUM PLANTS
Consider the size of the lamps, especially if you buy an aquarium with a finished lid. If any rare lamp is installed there, then it will be difficult to find a replacement later.
Remember that a 40W lamp is much more common and costs (standard, not aquarium) several times cheaper than a similar 25W lamp.
Remember to regularly replace the lamps, as their light output decreases with time. Therefore, it makes sense to use PC lamps, for example, having a longer service life.
Lamp spectrum selection
Regarding the choice of the spectrum all the time there is a dispute among aquarists. Especially it is fueled by advertisements about the need to use the very best spectrum of a company.
As stated above, there is no spectrum that “helps” plants and “interferes” with algae. If you have a sufficiently “good” spectrum, then intensity is more important to you than spectrum. If you have enough light, then the spectrum is not very important, and if you do not have light, the spectrum will not help you.
This is evidenced by the successful cultivation of plants in the light of ordinary lamps – LB (Coolwhite) or a combination of LB / LD (coolwhite / daylight) with electric lamps.

SOIL FOR AQUARIUM- SPECIES NATURAL NEUTRAL ARTIFICIAL
Trying to provide comfortable conditions for the inhabitants of domestic aquariums, we, willy-nilly, strive to reproduce in it the conditions that are characteristic of the natural habitat as accurately as possible. One of the most difficult tasks in this regard is to provide a normal light mode.
It would seem, what is simpler: he took the light bulb, hung it near the aquarium and – let there be light! But no. You see, a week later, either the water began to bloom, or the walls were covered with algae, or the plants that looked handsome from their former owner, suddenly took on a very deplorable appearance.
So something is wrong. You need to buy specialized lamps for the aquarium, giving increased radiation in the blue and red parts of the spectrum. As an example, we give Osram-fluora and Sylvania Gro-Lux.
Sometimes, in order to get well developed plants and beautiful looking fish, it is necessary to combine different types of lamps. That would not mess with the inclusion of lighting in the aquarium manually. You can instruct this automation.
The photo sensor in the room will monitor the general level of illumination and in summer, when there is enough light, turn off the backlight. A daily timer completely de-energize the lamp for the aquarium at night.
LIGHTING FOR AQUARIUM PLANTS
LED lighting type more and more enters aquarism, which is greatly contributed by changing the LED market.
Light Emitting Diodes (LED))
Light Emitting Diodes (LED)) become brighter, consume less electricity and have an increasing radiation spectrum …
LED lighting for aquarium appeared about 10 years ago, abroad. We, in Russia, still prefer traditional lamp lighting.
A couple of years ago, several companies producing aquarium equipment, decided to produce and equipment based on LEDs. The idea was to replace the traditional aquarium metal halide lamps on the market with more economical and durable LED arrays.
Red radiation in combination with Orange (Orange) is the main form of energy for photosynthesis of aquarium plants. This light enhances the formation of carbohydrates during photosynthesis, as it is extremely well absorbed by chlorophyll.
The zone of these radiations is one of the most important for all physiological actions in plants.
Radiation purple and blue (Blue) LEDs are needed to suspend the growth of stems, leaf stalks, plant plates. That is, this light makes your plants more compact, this in turn allows you to improve absorption. Such rays stimulate the formation of proteins and organic synthesis in aquarium plants.
The blue and violet part of the spectrum is almost completely absorbed by chlorophyll, which in turn creates excellent conditions for maximum photosynthesis intensity.
Green (Green) LED You may need to, if you need to give your aquarium plants a pronounced green color. Since its radiation actually passes through the leaf blades without being absorbed by it. The latter under their action become very thin, and the axial organs of plants stretch.
The level of photosynthesis in this case is very low.
Yellow LED creates a glow as close as possible to natural lighting. Yellow radiation, unlike warm white, does not reflect from the surface of the water and its light penetrates deep into the aquarium, allowing you to create an effective lighting as close to natural light as possible The intensity and type of lamps affects the health, color, photosynthesis and reproduction of aquarium inhabitants. Pick up the light with all the preferences of the fish and their natural habitat.
Many tropical species are not familiar with bright light even on hot sunny days, so an excess of light can cause them stress and deterioration in their well-being. Some organisms need powerful rays of light, as a rule, they are inhabitants of shallow tropical rivers, where the water is clear and the sun sends out rays within 12 hours.
Coral reefs in wildlife have settled in shallow bodies of water, so they also need to ensure good and bright lighting. UV radiation is very important for corals, the rays pass into the depths of the water, where corals and invertebrates are already waiting for their arrival, since ultraviolet light activates the process of photosynthesis.
LIGHTING FOR AQUARIUM PLANTS
So, acquiring an aquarium, it is necessary not only to have knowledge about maintaining water temperature so that the fish would be comfortable but also to know and understand exactly how to feed and care for the bottom inhabitants. Also, it is not unimportant to have knowledge about the lighting in the aquarium.
In ready-made aquariums purchased at points of sale, namely, in markets and zoological stores, they are supplied in lamp kits of the aquarium spectrum corresponding to the normal life.
Remember that any lamp can not be screwed into the aquarium. Not all of the white light emitted by a lamp can have a beneficial effect on the life of plants and inhabitants.
Everyone knows that white color consists of a whole set of colors, such as red, blue, yellow, green. The predominance of any of the constituent colors affects the light.
Based on the above written, it is necessary to make a choice what kind of light is needed for the aquarium.
For plants, as well as possible, suitable lamps emitting white light. Of the spectral component and the predominance of blue and red. This is necessary so that the plants do not die and become covered with unpleasant green mucus.
Therefore, when choosing a lamp, if the previous one has burned out, study the information provided to the manufacturers on the characteristics of the work of this production site.
You can also ask the professional breeders what kind of lamp company they prefer to use when maintaining and lighting their aquariums. If you are constructing a lighting with your own hands, choose fluorescent lamps in the light of which the colors of the red-blue spectrum predominate.
So, what kind of light is better for an aquarium, we understand on the basis of the proposed information.
But the conversation was mainly about fluorescent lamps, it is also necessary to pay attention to energy-saving lamps. They are gaining particularly strong popularity in recent times with a number of positive qualities and advantages over ordinary lamps.
Choosing an energy-saving lamp, pay attention also to the spectral indicators.
This type of characteristic is suitable in which the lamp should emit light in a red and yellowish gamut. In addition, plants lining the bottom of the aquarium need ultraviolet light in order for photosynthesis to occur at the pace they need. UV lamps are different.
It is necessary when choosing to pay attention to the characteristics of the lamp and choose those that emit a soft, non-aggressive ultraviolet, which has a beneficial effect on all life.
So that your underwater inhabitants do not feel discomfort, and the illumination control does not cause inconvenience, you should first calculate the allowable light power for the aquarium. It all depends on the type of plants and the displacement of the aquarium.
Freshwater residents are much easier to relate to this factor.
In contrast, lighting for an aquarium with marine plants should be selected more carefully. For the latter, the power is determined based on the ratio of lamp power and the number of liters of water: 1 W / 2 l. This means if you have a 100-liter aquarium, you need to install 50 W lamps above it.
Proper lighting of the aquarium. The choice of lamps. Pros and cons
- Lighting for an aquarium with incandescent bulbs is, in fact, yesterday. They shine a little and heat a lot, breaking the heat balance.
- Illumination with fluorescent lamps solves the problem of light intensity, but does not fully provide the necessary range of lighting.
- The lighting for the aquarium with the help of modern fitolamps provides both the intensity and the spectrum of illumination, but the light in the aquarium can be affordable for not everyone.
- LED lighting aquarium – the newest method of supplying light that is closest to the natural light of the sun. Lighting the aquarium with LEDs allows you to maintain a stable temperature regime of water. The resource of LEDs exceeds the service life of other lamps. Underwater LED ribbons provide an opportunity to adjust the brightness and color range of lighting, create fascinating pictures of “marine” life.

DIY Aquarium Lighting, LED Lights in Aquarium
One of the key moments of maintaining a healthy, beautiful aquarium with lush aquarium plants is LIGHTING. Highlights of the selection of aquarium lighting have already been covered on FanFishka.ru, in this ARTICLE.
Here, I would like to share with the reader my experience of creating a high-grade, high-quality lighting for an aquarium with live aquarium plants.
So, we will discuss the creation of mixed lighting: the installation of LED spotlights (hereinafter referred to as “SD projector”) in a plastic aquarium cover and a T5 fluorescent lamp (hereinafter “LL T5”). Also in this article we will consider the installation of coolers in the aquarium to cool the water in the summer.
CONSIDER ALL QUESTIONS BY ORDER:
– What is mixed lighting, why is it needed, what are the advantages?
– Why precisely LED spotlight? –
– Why precisely in the cover?
– Why do I need a T5 lamp?
– Choosing a cd spotlight?
– What do you need to create lighting with your own hands?
– The process of assembling aquarium lighting in the home.
– How much is it?
– Is it worth bothering? What is the effect?
What is mixed lighting, why is it needed, what are the advantages?
MIXED LIGHTING – It is a combination of different sources of lighting. A good example of such lighting is the ADA Solar I luminaire, where Takashi Amano combines a metal halide floodlight MH-HQI 150W with two LL T5 lamps of 36 watts each.
In general, if we talk about high-quality aquarium lighting, then in my opinion a metal halide spotlight (hereinafter – MG) in combination with LL is the best option. Such lighting “breaks through” even the deepest aquariums, the characteristics of such lighting are as close as possible to natural, natural lighting. Well, and a visual row, you just will please – sparkling glare of waves at the bottom of the aquarium, the shadows of plants and fish, natural, rich colors.
Why do you need such mixed lighting? It’s very simple to recreate the “effect of the sun” in your tank: the effect of sunrise, zenith and sunset.
Agree, the Sun does not fry 24 hours a day, the maximum intensity of sunlight is observed only during the day – at lunchtime. The rest of the time, the Sun either rises or sets, the intensity of illumination gradually increases and then decreases.
Approximately the same effect can be achieved with a mixed luminaire (lighting), when LL T5 (sunrise) is switched on first, then a searchlight (zenith) is added for 3-4 hours, and then (LL T5) again work (sunset) again.
The advantages of such lighting are clear:
1. Aquarium plants get the most natural light. Set a certain rhythm.
2. Prevention of algal outbreak. Powerful, long-lasting, and even more so illumination leads to the “greening” of the aquarium.
It is only necessary to create a peak of activity of lighting, and not to “fry” an aquarium for 12 hours a day.
3. At the same time, the presence of powerful, directional and high-quality lighting in sufficient quantities is the key to success!
Why LED led spotlight? Why precisely in the cover? The only significant drawback of the metal halide lamp is that it heats up very much.
Alas, such lighting can be used only in open aquariums (without a cover), at a distance of at least 30 cm from the surface of the water, while using hangers or stoics for the lamp.
When I decided the question of what kind of lighting would be in my aquarium, I proceeded from the assumption that the aquarium would be closed (with a lid). Firstly, the spouse wanted so much))), secondly, I agreed with her that the aquarium with the lid looks at home, as it is more comfortable, plus at home cats who watch “Aqua-TV” every evening, and all the same, the house is not an exhibition center and not an ADA laboratory … metal halide spotlights in a house are a bust!
But, here everyone decides for himself … my opinion is not a dogma.
So, an analogue of the metal-halogen spotlight is the LED. Immediately I will note the word “analog” in quotes … yet there is a significant difference. First, LED lighting, in contrast to the MG discrete.
Discreteness (from the Latin. discretus – divided, intermittent) – a property opposed to continuity, discontinuity. To explain on the fingers, below the photo example, what a continuous and discrete spectrum looks like.
Thus, we see that the spectrum of LEDs, to put it mildly, is not the best. And the thing is, not even in the peaks of red and blue, namely, that aquarium plants in fact, in the process of photosynthesis, absorb the entire visible spectrum, and it is deficient in diabetes.
What is the similarity between MG and SD, you ask? Why initially do such “poor-quality” lighting?
The answers to these questions will reveal the benefits of CD spotlights.
1. Like the metal halide spotlight, the LED has directional lighting. That is, the efficiency of LEDs is much higher than, for example, in fluorescent lamps, the effective use of which is possible only with reflectors. Speaking in everyday language, the SD and MG projecters “beat” one way, and not “sprayed” at all.
It is this property that makes it possible to “pierce” MG and SD spotlights the deepest aquariums and the water column of 60 centimeters or more.
2. Unlike MG, the LED spotlight does not emit excessive heat. Verified
From the front side, the LED searchlight does not heat up at all, and the back part heats up, but is tolerable (tolerable for a hand and a plastic cover). Some aquarists are advised to put a cooler on the CD for heat, but so far even now, when it’s 36 on the street, I see no need for that.
Again, this is not a constant, everyone has their own specifics.
3. LED lighting is by far the most economical lighting. You will save 3, 10 times on electricity.
4. A significant drawback, for example, of fluorescent lamps, is their flickering with a frequency that is noticeable even to the eye. In this connection, with a long-term effect of LL on a person, his eyes very quickly get tired.
LED lamps are powered by direct current, so they have no flickering.
5. Other positive aspects of diabetes: safety (work at low voltage, which is important for the aquarium business) and long life (up to 100,000 hours).
Why do I need a T5 lamp? From the fact that T5 fluorescent lamps are better than T8, I think they already know a lot, so I will not focus on this particular attention here.
I used LL T5 in my case, firstly, to create mixed lighting, and secondly, to make up for the discreteness of the LED spectrum.
Namely, the so-called “Full Spectrum” lamp was used.
Fluorescent lamp for the aquarium, designed to provide intensive lighting. The JBL Solar Ultra Color T5 lamp has increased power compared to standard T8 lamps and has a full range of colors.
When using a JBL Solar Ultra Color lamp in an aquarium, you will gain increased red and blue color transmission of aquarium fish and other inhabitants of the aquarium.
Having a higher proportion of red and blue in the spectrum, the JBL Solar Ultra Color aquarium lamp stimulates the synthesis of chlorophylls, which in turn speeds up the process of photosynthesis.
Naturally, this lamp was installed with a reflector / reflector. I note that I wanted to initially install 2 such lamps, for uniform lighting and good power, but alas, the dimensions of the cover did not allow to do this.
The choice of LED spotlight
To the selection and acquisition of LED spotlight must be treated with special scruples. This is a very important and expensive moment, without paying enough attention to that, you can simply throw your money away.
Since I am a pioneer on FanFishka, I had to subtract a lot of information, review a lot of characteristics of various projectors and LED panels, collect scant information on forums and talk with a few experts on the LED case.
And so, what conclusion was made! Per 100-110 l. Aquarium, net volume need:
1. Two LED spotlights. Since they have a directional light and one, albeit a more powerful searchlight does not cover the entire area of the bottom and the reservoir as a whole.
If the cover allows, you can put three spotlights (of lesser power), which will give you more confidence that the spotlights will not burn quickly. Alas, the repair of SD-spotlights are not subject.
Less powerful spotlights heat less, respectively, the risks are reduced. At the same time, the smaller the watt of diabetes, the less its “penetrating” ability and its other characteristics, too.
In general, all you need to calculate and estimate.
2. Everyone knows that LED lighting is much more powerful than the nominal. That is, the power of LEDs in watts to measure at least not correctly.
So I asked the question, but how many watts then is needed in my aquarium. To believe the sellers in the market who say: “Multiply by three years and there will be those real wats” is stupid!
In general, I had to rummage in this matter and find clearer information.
And the truth is quite simple, lighting, in addition to watts, has a lot of characteristics, including the so-called Lumens – is the amount of light emitted / emitted by the light source. A light source with a luminous flux of 1 lumen, which uniformly illuminates any surface of 1 square meter, creates on it (surfaces) an illumination of 1 lux.
Experienced, aquarists have found that for a good herbalist, for the Dutch and Amanovo aquarium, you need 40-50 lumens per liter of pure water.
The task was solved and the choice of searchlights became extremely specific – you need two searchlights so that in the sum of their Lumens they give 50 Lm / l.
3. And the last two important points when choosing a CD projector are all the same: spectrum and Kelvin.
As it turned out, the searchlights were full of variety: there was a warm glow, a cold glow, I even came across RGB searchlights (and for a long time I understood what that kind of thing was))). But, we only need one searchlight – with a spectrum as close as possible to daylight.
This type of LED has the best characteristics.
Kelvin (K) – This is the color temperature of any light source. This is the measure of our impression of the color of this light source. For maintenance of aquarium plants, it is recommended from 6500 to 8000 K.
