Well, it looks like for a hand-held "pointer" type laser, 5mw is the legal limit in the USA. So, to get the brightest possible unit, you would want one that is: A. Actually optimized to put out a true 5mw. Many sold as 5mw are actually under that figure, typically between 3mw and 5mw. The term "5mw" can be used as a marketing tool by some sellers. The honest ones will list a true output, within a reasonable margin. -AND- B. Continuous-duty cycle. As discussed yesterday, some of the lower-priced green lasers use a 50% duty cycle, and are noticeably dimmer than the continous-duty type. After all, they are only "on" half the time. If all one wants is just a 'green laser' with a reasonably visible beam, then let lowest price dictate the purchase (the venerable 5-D-cell flashlight still works great for a fraction of the cost). If one is after best laser visibility for one's money, then let price be just one of several criteria. I'm still shopping for a street-legal unit...but also having a friend living in Korea do some looking-around for one of those 100mw babies! ;) __________________________________ Yahoo!
