[PSUBS-MAILIST] LED lights

[hank pronk via Personal_Submersibles]

 Jon,I have noticed looking at pictures from other subs that the spot light, lighting is spotty.  There are dark areas in the images.  This is an image taken a week ago at close to 300 feet in the darkest water I have ever been in.  Notice how even the lighting is and the light goes beyond the camera view.  You can make this light for a couple hundred bucks maybe 300 with hand tools.  I have had this light for a long time with lots of dives even to 435 feet with zero issues.  I tested one that I made for a friend to over 1,000 psi and another for Scott to over 3000 psi.Hank

 Off the shelf LED lights.  Finding this frustrating, lots of crap available and by looking at hundreds of youtube reviews I've learned not to depend upon "lumen" claims.  Looks like you can't even trust many of the wattage consumed claims.
I bought a harbor freight ROADSHOCK (see link) to poke at just because they were inexpensive.  Turns out they are very well made and look like they would be easy to oil compensate.  I like them.  However, they are not very bright at all, only burning 15 watts.  I'm tempted to get one of the light bar models that burns 47 watts but at $65 there are much cheaper alternatives on Ebay.  Only problem is, how easy will those others be to pressure compensate and keep a seal?
Alec Smyth, if you are reading, what was your experience with those 4 inch LED work lights you pressure compensated a few years ago?  Those are still sold and are very inexpensive, and burn as much wattage as some of the more expensive light bars.  Did they hold up?
