I'm in the market for a new backup light. I had a UK SL6 and loved it. I lent it out and it was lost. I've been reading about the UK SL4 LED. Has anyone out there dived with both of them and can tell me which one provides the most light?

There is the link to the emitter you need. after you get one of those you need a small piece of I believe 1" ID AL tubing that has a wall thickness of 1/4" giving it a 1.5" OD. in other words, either 1" ID or 1.5" OD aluminum tubing with a 1/4" wall. you then need to cut it so that it is as tall as the widest part of the reflector that came with the light; I think its somewhere around a 1/2". the final step is to squeeze it together in a vice, make sure you separate the reflector from the rest of the module before doing this. when you put it in your light make sure you put the batteries in backwards. the first set you need to put + side in first and the second set - side first so that when all of them are in there the + side of the battery is sticking out. I'll take some pictures of the process tomorrow, but this is what the finished product should look like.
NOTE: the batteries in the SL6 are also in backwards because it has also been upgraded and I didn't feel like taking batteries out for photos.

marchand,
That's very cool. Why did you use the clamp in vise method rathere than glueing them together with thermal epoxy? That would help to take advantage of the extra aluminum for th heatsink.
I've been looking for a way to upgrade my backup, and you've given me an excellent idea, thanks!
