I'm looking into planted tanks and at the moment I am doing some readings on different lighting.
One problem though: I suck at terminology :(
I see stuff like T5, T8, T5HO, T8HO, LED, etc (it feels like the list goes on D:)
Can anyone make a list of the lights and explain in some details the differences in terms of size, watts, Kelvin, and anything else that is important?
Also, I have a AquaGlo 18inch 15W fluorescent light bulb. What category of lighting does this fall under?
