The lights I was testing out on the left hand side of the tank was actually a cheap Chinese colour changing LED floodlight.
Can get them for about $40 each off eBay.
They were the 30watt version, I can remotely change the colour to any colour I want, also increase or decrease brightness.
Only fault I have with them is the blue colour selection is too blue, I would have liked there to be lighter hues.
I would probably only ever leave them on white for normal use. But the reds,green purple etc is fun to muck around with.
