I picked up a couple of those lights, and threw them on top of my 15. They appeared to put out as much light as my 2X65W PC fixture. I am just building a top to make them more permanent. :biggrin:

For a 20Gal tank would u only need 1 10000k and 1 antic?

The tank actually never went to Desmonds. It got stored in my garage the day he picked it up from you. Then it became mine :lol:

They don't sell any antics, but you could use one 10000K and one Actinic, or even better would be two 10000K and one actinic. The fixtures are quite small, so you could easily have three of them side by side. That's the way I built my top. :biggrin:
