Default Re: 5mW 450nm Laser

^Purple isn't 450nm. It's 405nm, and I'd bet it's a typical 30mW. Our past experience tells us blue, violet, and green "5mW" pointers are very rarely under 5mW. And if they are, they're 0mW.

LAWL @ "probably"

What do you think is more likely:

1) They've relisted the power to comply with rules
2) They've used a unique diode so inefficient it makes selenium rectifiers look like perpetual motion machines

3V boosted to 4.5V assuming an 80% efficient driver means driving the diode at ~180mA and only getting 5mW of light out. Not gonna happen, sir.
