No way it can be 520nm. The diodes themselves(regular 50mW) ones are I believe $50 a piece already, so unless you are buying in bulk(even then) not happening :p

Even on its description it says to make sure to keep it warm before using on a cold day. Wonder if it was "good" advertising or an honest mistake:thinking:

It tells on it's self where it says optical pump.
It's no doubt a 532.
But keep your ear to the ground, you never know when China will start flooding the market with inexpensive 515's or 520's, dare we dream maybe a surprise 495 or 500, that would be very pretty.
