Zoo Med 18 Inch Ultra Sun Flourescent Bulb (T8 STD Output)

shopped long and hard for these bulbs, as the hood of my tank is very picky as to the type of bulb and watts it will take. well needless to say, I am very happy with this choice. my plants are doing great (growing), and just a side note, i do have a layer of substrate, now i don't know if this helps, but sure cannot hurt. my fish seem to enjoy it as well and during most of the year, don't need to use a heater in my tank, stays about 76 degrees (F), 30 gallon tank.

I like the fact that this light has no strong tints to it. It also worked wonderfully. However, this model is a T8, and if you need lighting for aquatic plants, you're better off with at least double T5s.
