Aiya, should have told me earlier, I don't have much time recently to go out to Pasar Road, it was selling RM50, normally it is RM52, that day the Boss (lady) chincai sell to me at RM50, haha
Oh, the light ah. It was came with a loose LED module, so I tighten it, but then the body won't touch the LED (-ve) side, so no light.
I put some tin using a soldering iron, so it will touch the -ve, and it is common China Made QC, but don't worry, all my Chinese light works perfectly.
Hey, I didn't check is the Lens has O-ring, if not, then you might need to put one, sometimes they FORGOT to put in an O-Ring at the lens.
Hey, want to share this light with you guys
http://www.dealextreme.com/feedbacks/postreview.dx/sku.31730Its uses a plastic Lens, no reflector, like those surefire TIR lens.
The hot spot was so tight, and almost no side spill.
Can take AA, CR123A, RCR123, 14500
its sucking 1.6A from a fully charged liCo 4.2V (suspect direct drive)
and compare to my surefire E1 Backup, its actually has a brighter output
Brightness is good at CR123A 3V or LifePO4, but dim for AA
but for the price of RM48, hehe

you can get a E1B output, and Nitecore look flashlight
hotspot has a blue ring at the outer sphere, no harm if you use outdoor, though
The 3 mode is the interesting part, it always start with High, and you need to press it very quick to change mode to Medium and strobe. Which I like most. So you Off and On the light, it won't switch to next mode.
I bad thing is that, the Emitter is not glue into the driver module, it just sit on it with some white thermal paste . the Emitter is somehow snug into the TIR lens, and when u close it, it will press the Emitter heatsink into the driver module (aluminum), with the thermal paste, it get the heat dissipated.
SO far, running on High for 10 minutes is ok, but light get heated up so much that you can't really hold it.
