If it is 26W, then i am outputing about a 2 - 3 Watt / gallon, which i guess should be fine. My lamp is not sticking to the aquarium, has a bit of space in between, though not much. Here is the lamp i have: IKEA | TERTIAL | Work lamp
I dont understand the two light bulb setup, do you have a pic, just wandering for design purposes and to give me new ideas.
With that fixture, a 20w CF bulb will work. That seems close to what redchigh mentioned having, he can comment further.
As for the intensity/watts thing, the CF bulbs are supposedly equivalent in intensity to the old incandescent bulbs according to the watts. For instance, my 10w CF bulbs say they give out the same light as the old 25w incandescent. Use that as a guide, a very rough guide. All I can tell you is that my two 10w bulbs over a 10g and 20g (which are not much different in surface area or depth, which is significant) are perfectly adequate. Here's of photo of the 10g at present to illustrate.
