50mW 532nm 3.0-3.7V /Laser Diode Module/Green Laser - eBay (item 260541750065 end time Jun-20-10 20:29:51 PDT)
I could not find any reviews or conversations about these modules so allow me to start I guess.
(Sorry I have no way to take pics.)
SHIPPING
Shipping took about 14 days to the west U.S. The module came in what looks to be ab airproof bag. It was secure in it's bag in a box and on the box it said "VERY FRAGILE!" It was secure that's all I can say.
PERFORMANCE
It is a little off center but it was only about 2 degrees going up. I got this one instead of the DX one because I don't really trust DX that much, so I got this one hoping in vein it was good. This thing is able to pop balloons instantly, smoke black leather, shut off streetlights, and even sting my skin after a few seconds! Only once have I left my laser in my pocket and it changed from TEM00 to TEM01. That's probably because I live in Phoenix and anything im my pockets will overheat if I'm outside, even my phone! Visibility is almost the same as my friends True 50mW except it is a little brighter. This laser does emit IR. You have to be exposed directly in the beam to worry about IR but it's nothing to crap your pants about.
SPECIFICATIONS
Wavelength: 532nm
Power output: 50mW with 5% tolerance
Working Current: <350mA at 3.0V-3.7V input
Electronical Pole: Copper burl to"+" and Spring for "-"
Working Temperature: +10dgC-+40dgC
Storage Temperature: +10dgC-+50dgC
Duty Circle: 60 seconds on and 5 secons off
Lifepan: >3500hours
Size: 12mmx55mm
CONCLUSION
For its price, it's not bad. I completely recommend this to anyone that just wants a really bright star pointer and presentation pointer.
