Doesnt matter, the diodes are all the same. I extracted these from the V1. Yes you can run them up to 5 A, but I dont want to overdrive them too much in my builds. Its better to have a product that will last, than one that will have an extreme output but die quickly. :beer:
You know I've built at least six lasers using sinners Envy host. It is an elegant design that is more impressive because of its simplicity. But, I never had any with the copper core in them like this one has. A NUBM44 diode in one of these is a beautiful build to behold. Anyone would be lucky to own one of these beauties.
