Default Re: 5mW vs 50 mW green laser

The color of the outpout is measured in nm. 532 is green, 442 blue, 405 violet, 650 red. Anything above 750nm or bellow 400nm is invisble (infra-red and UV). Power is measured in Watts. 1mW is 1miliwatt, or 1/1000 of a watt. So, 50 mW is 10X brighter than 5. Also, the eye is able to see some colors of the spectrum better then the other. Green is one of the best. For a graph, se here, at the top of the page.

For 50 mW, look at this :

Oh, and if you want to buy some, consider this : US buyers can't buy at Dealextreme because of FDA regulations. But you can buy at www.o-like.com. Great service and price, ships US.
