Battery lasted almost 2 days of fiddling, never on for longer then 4 minutes for burning. Using Lithium photo cells

No optics besides a collimating lens.
Good to know.

Just out of curiosity, why DL calls it 447nm if it's a 445nm?

It's a CNI thing. CNI (who makes these lasers) markets them as 447nm, so that's what DragonLasers passes them off at.

445 or 447, it's only 2nm difference. CNI probably checked their diodes out using a spectrometer first.
