Ausie, are you sure that statement about the laser sights applies to hogs since they are non game animals in Texas. Might be something to check into.

Also, I hanen't had any luck on your light so far, but I did think about a couple more solutions. The low voltage landscape lights have a 20-50 watt halogen flood light that you can get. You will typically see them used as up lights on the front of people's houses. I would think a couple of these attached to the marine battery would be plenty. You could alyas set them up on a switch at or near your stand so you could turn them on or off whenever you wanted to. Finding a 12 VDC motion sensor might be a little tricky.

The other thing that you could do is make some like we saw on that hog hunting site. Just get 3-4 red high intensity leds and put them in some type of housing to keep them waterproof and that should be plenty of light. Let me know if your interested in looking into either of these options. I have a brother in law who is an electronics whiz and I'm sure we all could come up with something that would work.
