Another great DTR addition (35mW 635nm)

is the color different from 658nm? I have heard that anything beyond 650nm is for all observable purposes visually the same color just dimmer.

I have a 685nm diode that I need to get lasing one of these days.

It´s definitely a optical noticable different wavelength.

Here is a quick comparison, gonna also add 650-660nm sometime.

For your 685nm, make it lasing, you won´t regret it :beer:
