I have the Kodak Zi8. Can not beat the cam for the price. Use it for my company as well.
I am using the Deep Blue Solarxtreme 4x T5 setup. Has 8 blue LED for moonlight lighting that stays on 24/7 and after a few hours of the lights turning off, 4 LED's shut down and only 4 run. I love the integrated timer on this unit too. So far no problems with it.
