300-2000mW? Yep, description is misleading but technically true.
The nichia diodes can be powered between 300mW (roughly lasing threshold) and max out just over 2 watts.
They are probably powering them up to ~1 watt based on the 5000 hour expected life.
Overpriced, get them from a LPF member instead, ours are usually up to spec and built with loving care ;)

*edit* The part about TEM 00 is crap though, these are multimode emitters. There is no possible way of getting a true gaussian profile.
The divergence is also bull$#!t, these diodes just aren't capable of that little divergence without very costly beam expanding optics.
Why are alibaba sellers always gender confused men posing as women?
*edit#2* Just noticed this seller only wants western union, moneygram etc. This is a scammer's method, there is no recourse if you don't get your item. I almost bought a sportbike a while back but a little research showed what the real deal is. Sellers using these methods deserve to be shot with a ball of their own...poopy

There is also no way to run it off 2 AAAs Not enough voltage and the current needed from the batteries to boost would bow the little Alkalines up

True, they probobly stated that wrong to.


further down it states that it uses 2x 16340 wich we all know is what it should use just like those that rayfoss and o-like sell.
