Like many others here, I bought this from DX offers for $7.??. Actually, I ordered 2, but should have ordered 5.
IMHO, a $10 light isn't often worthy of a formal review. Just buy it:)
But, I figured I'd start a thread for it, to show a few pictures and here how others guys use/modify theirs.
So...after about 2 minutes of trying this light out, I decided to take the head off.
This is really easy, if you have a couple tools - but before you just stop reading and get started, know that it is a little bit harder to put back together than it is to take apart.
I simply put the right angle portion of the head (plastic) in my vise (w/ wood inserts on jaws) and left the aluminum portion of the head out to the side where the jaws weren't touching it.
I wrapped the widest part of the head with about 5 layers of duct tape, locked some vice grips on and twisted it until it made a sickening crunching sound as the glue broke away.
Then, just unscrew the head - BUT, as soon as the head is free from the threads on the neck, turn it back the other way (without threading it back on) - the wires inside will be twisted into a spiral from unscrewing the head, and when they un-spiral you will be able to move the head further from the neck.
The 'pill' is the smallest one in the world - just a disc the size of the emitter's board. It is threaded into the reflector. Unscrew that (divots on the back), remove it and the emitter, and then you can unscrew the 'reflector'.
I took the reflector, polished it, tested and found it too ringy, so I taped the reflector inside a can w/ BBs and shook it until they made it OP.
NOW this light's beam profile matches its body design - FLOOD! As you'll see in the photo captions, I also tried two different asphericals that I salvaged from other lights.
I absolutely love this light - and I will probably mod to xml with ucl lens in one and floodier aspherical in the other.
One other note - remember to clean off the glue before reinstalling - I didn't and I think a long run on high made the glue reset Also - wind the wires into a spiral (counter clockwise) before you screw the head back on!
These beamshots look pretty terrible - they were taken w/ a cell phone w/ brightness setting turned all the way down and the only real purpose is to demonstrate change to beam profile...
