dog17simon ffmike- ive got a 12g eclipse also what kind of corals are in your tank did u get the retrofit light or are u using the one that came with it?
No, I did not use the light that came with it. I took out the old ballast and set 2 nine inch PC's on top of a piece of plexiglass, layed across the top of the tank. The lights are 18 Watts each and a friend of mine who has been at this a while said that this would be enough light for most corals. Each light was like 40 bucks, so for 80$ you can have plenty of light and everything tucks up under the original lid.
Here is a pic. sorry it is kind if dark. I will take a better one with the lid off and show you how i have it.
