Sorry havent found much net material on lights, had to just go for it. Glad I did, installed the uv and threw in some pretty blue ones as well. To let U all know if they work....first time I had boat out to test them which has been a while ago, my spot light went out on me half way back to the ramp, sure glad I put the blue lights in there, didnt have to worry about running into anything. Funny thing was that I only installed 200 blue lights, if I would have put 100 more lights on my rig, I would be comfortable letting my 6yr old swim outside around the boat at 2am, prolly gonna install the 100 extra lights this winter.
