To anyone in this thread considering buying one of these lasers, PLEASE consider buying quality laser safety glasses to protect your eyes against this wavelength (532nm). (Sunglasses and welding goggles DO NOT WORK)

 Reflections from shiny surfaces alone can cause permanent vision damage. To the person earlier who said this is like looking into the sun, it's quite a bit more power than that. If the laser can ignite a match, what do you think it will do to the delicate cells in the retina of your eye?



Rant aside, OP do you guarantee that the laser can sustain an output power of >400mW for at least 30 seconds? If so I'll grab one.
