>>A 15 watt FL bulb will put out about 4 times minimum (about, with something like PC or T-8's about 5 or so) the equal amount of incad light. So 15 watt bulb will be like a 60 watt incad bulb or 75...<< Well I am glad somebody brought up the obvious. People have a hard enough time cramming enough standard flourescents over a tank to reach the desired light level, (2 or 3 watts per gallon, if you want to use that as a unit of measure), considering flourescents are 4 or 5 times brighter than incadescents, the number of incadescent bulbs that would be needed to equal the same amount of light is mind boggling.
