I need to design an underwater light that will put out a true 10,000 lumens. Or maybe a 5000 lumens and make two of them.
I don't care about distance. Anything more than 30 feet of underwater illumination is irrelevant. I need wide angle.
Not brand new to the forum, but fairly inexperienced in the led world. Do have a rusty crusty electronics background.
I saw on another thread the XLamp CXa2011 can put out 4000 lumens???
I looked at the cree website, looks like it runs on about 40 volts. Was considering several 12v lawn mower batteries in series, or one car battery with some kind of voltage booster.
How would YOU design this. It's going to be underwater, so it won't burn up , will be mounted to stainless steel most likely. But I also need enough heat sink it can be out of water for a few minutes without damaging it. Interested in choice of emitters, voltage regulation, etc
Thanks in advance
