rubone, I have a Stanley FL5W10 LED spotlight, avail for about 50 in wally world or auto parts stores.
Waterproof on the surface with rubber seals .
I don't use it when there are people around as I don't want to draw attention to my area when I'm catchin.
But it's great for a lot of uses...I spend a lot of time in the Western sound at night, T&W and trolling. When I get near rockpiles in the summer, I shine that light and after about a minute I'm surrounded by spearing and rainfish. The sound of them moving in the water is incredible.
Check it out, I highly recommend this light. For filming I have found that you need to shoot your light away from the subject if there is no ambient light.
Well I got my second light today and just ran a test with the two lights. I'm not going to show the video here (when i build my new mount with the cam and two lights Ill run a new video test and post it).
Ill tell you what I have learned so far . 1st you can not have enough light, I have tried to defused the light it didn't work it widen the angle of light but also weaken it also. When I ran the test tonight with the 2 lights I had both beams of light shining in the same spot I still got the tunnel vision effect ( I THINK BECAUSE OF THE WIDE ANGLE LENS) When I tried to separate the beams of light so they would be side by side and in effect widen the light in the area. This just weaken the amount of light and the picture or the video suffered. I have had people here and on other sites come up with some pretty good ideas and have tried some too. Here is what I think is the bottom line the GO PRO needs so much light outside at night to work right!! Now there are things you can do like changing your lenses or putting a I R LENSE IN WITH I R LIGHTING I just cant get into all that right now. Ill be building a new mount soon and Ill post pics of it. And in less then 2 weeks Ill be night fishing for Bass, I also think that since ILL be filming so close on the kayak that I will be able to separate the beams of light and therefore broadcast over a wider area. So thats it guys thanks for hanging in there and for your ideas.
