I have been searching non-stop on how to convert a 4D mag into a LED canister dive light. I've found plenty of post, but all of them seem to be started by someone who know's what they are talking about....thats not me!!
I already have converted a 4D into a 50W halogen canister light, but decided that i'd be happier with LED instead of halogen, because of burn time!
Honestly, I don't even know where to start!
What is the best route for me? I want PLENTY of light/burn time, but think it would be nice if I could control the levels of light (unless that is too difficult for a LED beginner to attempt to accomplish).
Any suggestions on how to accomplish my goal of a LED D-mag canister light?!
I don't understand much of the LED talk that i've read....
What type of LED, reflector, driver?, batteries, and whatever else...should I get? I have a 12v SLA battery but would prefer to switch to NiMH (so I can put it into a tube instead of a box).
I've thought about just using this: http://www.dealextreme.com/details.dx/sku.14645 , trimming it to size, adding ambilical cord to canister, replacing lens with glass and epoxying all joints... ?
If you've got other ideas to get me started that'd be great!!!
