Just got my 505 sb147ec91 and 450pltb450b from jnrpop! Shipping was pretty fast from Germany and the diodes are amazing. Don't have a picture of the 450 on hand, but we only drove it at 700ma. The 505 however.... More to come when I put it in a host! Definitely a very positive experience...

Hey guys, So I've had my hl532-300 for a while now (laserbtb 532nm 300mw), and ive always been disappointed by the runtime i get with it. It runs off of a single 16350, and i usually get about 45 seconds to a minute of run time before the power drastically drops (not 45 sequential seconds) I...

Hey guys, last time I asked about glasses, I was told not to cheap out, and to get a nice pair for my 300mw 532. Boy am I glad I did. The eagle pair glasses are very nice and appear to offer lots of protection. Now, I want to teach my nephews about lasers and laser safety. They've all used...

So as the title says, im in the market for a greater than 200mw 520nm "diode green" laser. After my recent mishap, im looking to not get some piece of crap inexpensive chinese laser, i want the real deal. My ideals: Focusable Takes an 18650 (ive heard theyre amazing at dumping a ton of power)...

Hi all, I recently purchased a green laser pointer, just for the sake of maybe i got a bad one, im not going to say from where. Anyways, i spent around $130 for it, it has and adjustable focus that seems to work quite well, but it just does not seem to stand up to what ive seen other 200mw laser...
