| I'm guessing thats 75watt equivalent? If you are looking at the watt to gallon rule like for plants or whatnot you should be using the real wattage. But yes they do work well for plants or just for looks. I have 4 14watt CFLs over my 55 gallon tank. You can see pics in my members forum, there is a link in my signature.
Reefs, I would advise against it since reefs have a lot more lighting requirements. I think it is doable if you research into enough, I plan to try it later this year. Once again though, I would highly advise against these for a reef unless you do heavy research into lighting requirements for coral. |
