I got a tupac of these

a long while back on a vipon, but they’re regular price now.

They say “30W” but they draw something like 18W constant above 9V-10V or so. Above that constant-wattage point, as voltage goes up, current draw goes down. Before, I was afraid to drive it with anything more’n 12V, but after playing with it on my “lab supply” and slowly cranking up the volts, I could see that it’s internally regulated.

50W version here Amazon.com

I wonder what LEDs those are??

To me they look like some sort of cree CXA leds.

Those specific bowfinsing lights look rather pricey! Could you consider a led lightbar for offroad cars and trucks and swap about 80 little chinese emitters?

Something like this. You could swap about 50-120 of these little leds. Stock is a bluish 6500k.

These even come as a 10 pack. Id choose the yellow version. The benefit of these is you do not have to reflow solder because of the little arms. Its a light bar so should run off 12v vehicle battery.

All great ideas i hope to figure out which im doing this weekend as far as submerging the lights we do two types gigging and bowfishing gigging is laid back slow predictable bowfish is not we drive over land aligators stumps etc not good for underwater light but it does work very well
