SUPER BRIGHT*MONSTER* GREEN LASER*5 MILES+RANGE* MILITARY GRADE*U.S.A.SELLER* | eBay



I am going to find a optical power measuring device here at college, and try to see if it really is 30mW. Would i go to the engineering dept or astronomy dept?

So Krazy Ken is selling lasers that are over 5mW on ebay :thinking:

I dont ever remember there being a law that you cant sell things over 5mW. I do remember that the FDA says it has to have a safety switch.

Laser pointers are Class II or Class IIIa devices, with output beam power less than 5 milliwatts (<5 mW). According to U.S. Food and Drug Administration (FDA) regulations, more powerful lasers may not be sold or promoted as laser pointers.[51] Also, any laser with class higher than IIIa (more than 5 milliwatts) requires a key-switch interlock and other safety features.[52] Shining a laser pointer of any class at an aircraft is illegal and punishable by a fine of up to $11,000.[53]
All laser products offered in commerce in the US must be registered with the FDA, regardless of output power.[54]
