 Brian,I tested automotive LED head lights and they suck because they rely heavily on the reflective back.  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?
