If you have already read all the characteristics in the section describing different types of lamps, then you probably have seen such as the color temperature of the lamps. It is measured in Kelvin (K).
The fact is that the hot metal at different temperatures produces different light, say at 3000 degrees Kelvin is a yellowish tint, and at 6000 degrees Kelvin is a bluish tint, we decided to apply this scale of shades of hot metal to all lighting fixtures with a visible spectrum.
Fluorescent lamps have a rather high color temperature, above 4000K. The color temperature depends on the spectrum of the lamp and, accordingly, for lamps with a temperature of 4000K and higher, blue prevails in the spectrum, and for yellowish lamps with a temperature of 3000K, red dominates in the spectrum.
T.O. You can roughly pick up a suitable lamp for your aquarium if you do not have the spectral characteristics of this lamp but have the value of its color temperature.
The pictures show the spectra of lamps with a high color temperature (left) and low (right). Lamps with a high color temperature can be installed in aquariums where there are no plants, in marine aquariums. They can be put in aquariums with plants, but the luminous flux will have to be calculated with a margin.
Lamps with low color temperature and a large amount of red in the spectrum are ideal for plant aquariums.
The only drawback of these lamps is that the yellow tint doesn’t look as beautiful as the bluish one, but this problem can be easily solved by installing an extra lamp with a high color temperature for the backlight.
The most important thing is that nothing prohibits you from combining lamps to achieve the best results in growing aquarium plants, as well as giving it a beautiful aesthetic appearance.
