This one metered at 75mw peak with no ir leak.

The other one no pictured which takes a single 18650 peaked at 55mw and no ir leak.

both are actually very stable and all dissemble all the way down to the circuit board unlike the 301-303 lasers. Tonight i will update this thread with lpm graphs and more photos :D

A little bumming I really was thinking there would be more but hey for the money maby you got a OK host. Did you see a pot on the circuit board?
 
i got some ebay lasers and specialty one i have its a PM - Laser its around 271mW
i got 2 of it and i brook the crystal of to see the difference and the IR laser is different compare to other 303 lasers the Ir diode is 5.8mm and the front is different its round hard to explain i may take a picture, then i measure the IR its 508mW i may post some pictures later :)

Click to expand...

i just added photos of the circuit board
 
Can you share a link to the seller, or is that not allowed?

I am sort of looking for something that someone has already tested that doesn't leak IR that doesn't cost a bunch.
 
hm there must be some ir leak as those lasers dont have any ir filter usually installed ?
