If I wired it different it could a little brighter. It is brighter than it looks in the pic, but my camera hates the blue light. I haven't figured if that one is too bright or not yet. I can post pics later of the cold cathods running on my 55gal. With those I can control the brightness. If they are fully powered the fish will stay awake. Heres
a site that goes over how to use cold cathodes. Installing them is your hood is harder than wiring. Most people have a spare ac/dc converter that will work to power them. These are like old phone chargers, toy chargers,ect. Any of those plugs that are big bulky square boxes are usually ac/dc converters. It will say what their output is. That page gives some figures to which ones will light and which ones won't. You usually don't need to cut up a adapter unless its got a really tiny plug on it.
