Thanks for the comments guys. As for
http://www.fishinglightsetc.com, ask for Tom the owner at 1(785) 259-1343. We talked several minutes before I actually made a purchase and he made sure I had what I needed and understood what quality product I was buying. I was surprised I was speaking to an actual person and not some message board operator.
Tom is down to earth and was able to answer "all" my questions regarding battery/amperage draw, light/lumen power and as Jim said the website itself has a chart you can refer to. I am completely satisfied with my product that I've had for just about a year now and no complaints.
I imagine that my above listed project I made with 1 1/4" PVC can be adapted to just about any kayak if you use your crate. It makes for easier mounting, transporting and no drilling or gluing. Plus when you want to, you can transfer the lights back into the 1 1'4" PVC "hand-held" set up or even to up to 4" PVC and make you a floating portable fishing light dock!! (I'll post pics of those later). These come great in pairs because of their power and low battery/amperage draw. If you have any questions about my project, post 'em here or PM me. -Hector
