i need someone to help me to design and build a powerful multi led light into a wood speargun. i am willing to pay . i dont have the electrical skills to do this. i am a custom speargun builder, / woodworker. what i want to do is have the bulbs on the end of the gun, wired remotely about 5 feet , where the guts and batteries can be housed in a waterproof container in the rear of the gun. this would be submerged in salt water at depth for extended periods. but the guts and batteries would be in a waterproof housing (built by me) in the rear of the gun . the benefit is, : the water will cool the bulbs, so heat buildup is not much of a problem. but space is. the batteries cant be huge. maybe 6 or 8 aa battteries max. it needs to be pretty bright though. maybe actuated by an (embedded into the wood by me) magnetic activated reed switch. so i can turn it on/off with a small magnet sewn into my dive glove. repeat: i will pay. what i need is maybe someone to build the thing with parts i will buy, and sendit to me, with a diagram, so i can just put it in place and make a couple solder joints. i will pay for this. please help
