520nm HD 250mA Defiant (extended copper sink)
Well I had finally put together a 520nm build using a diode from our local supplier
... at this point of the game I did not even think of the efficiency of my diode, but I think I did good
1. PL520 diode
driver set @250mA
3. 1 Home Depot Defiant host 19.00 US.
4. 3 element 445nm lens
5. Copper heatsink, module, driver sink.
6. 1 22500 bat.
7. Arctic silver paste and Arctic ceramic adhesive.
One thing to mention is copper sux to work with

Using copper means finger prints right
... no, you must clear coat it
Why jander, why the copper driver sink?... cause I can. Muhaaaaa
