I ordered the Green 520 @500mw and its one of the best bangs for the buck on the planet! I tested with their Pocket LPM and a Laserbee (several tests on several lasers and both LPM's were always no more than 10mw from each other) and they both showed my model 890 at over 660mw with a max of 674mw with fully charged batteries. Maybe I just got lucky with a great module inside, but this thing is worth every penny and then some! Very well built with a light aluminum host and focusable front lens. Get it. You won't regret it.

Great color, terrible optics
This laser is hefty and ergonomic, and its teal beam color is absolutely gorgeous. The optics, however, are very poor. Rather than a pinpoint accurate beam, there's a large rectangular shape cast on your target surface along with the bright spot. Very disappointing.

I cannot get the batteries right you recommend the 18650 but this is only 3.7 volt and gives a very poor light I tried using 2 x CR123 Lithium non-rechargeable and these work well at 2 x 3.7 volts (7.4V) is this higher voltage what is needed?
