As seen on Tor.com, a Class 4 blue diode laser, 1 W output...built into a lightsaber body. I see no way that this can possibly go wrong. Really, just because stray reflections from this thing are bright enough to cause permanent blindness is no reason to be so negative.
I'll have to send this link to the site Laser Safety Officer. He's in the next building over, but I might be able to hear him when he opens the email.
