Ok, a couple answers here: First, I am actually babysitting my friends 55 gallon which has a fluorescent setup (2 white and 2 blue), I'm not sure which K
the lights are but I MUCH prefer my led
. The colors are brighter and the whites are more white. Also, you can use a short hood because it it maybe 2 inches high.
It was easy to mod the light. There is a 3 position switch (off, blue only; or all on) remove the switch and get another 12v power supply from Radio Shack. Wire one to the Blue only and one to the all on. Solder the other to the common ground and plug them into two timers. It's ok if they are both powered up at the same time. I have the blue come on first, the both on, then White off, then all off. Easy!
How is it difficult with the light installed? I have a full glass cover. I slide the light back a couple inches, then open the glass top.
