Not true at all! The rules require additional safety mechanisms (exit cover, lock, etc) above 5 mW but if present it's perfectly legal. I made my 175 mW "pointer" legal a while back for about $15 and a little extra length for the lock.

I don't think a single DX laser complies with the above-5mW rules, hence the warning. In the past many were found to not filter infrared at all(!) hence my warning they can be hazardous.

(the 175 mW greenie would be useless as a rescue laser as it's far too powerful)

A red Greatlands is a diode laser and inherently more rugged the the green laser, which is a DPSS and therefore more fragile. Both have a focusing optic and won't be quite as durable as an LED flashlight.

I could not find a reference at Greatlands web site as to whether the red Flare is a 650nm laser or 635nm laser. 650nm would be a lot cheaper; 635nm is 3x as visible to the human eye. NV goggles probably don't care.
