Default Re: ROUND 3 SOLD OUT!! - CHEAP 445nm (true blue) 5.6mm diode group buy.

Ah... that explains it . I was assuming that it had the same pins as the PHR-803T diode

Now, let get busy building it

THANKS... again...

Umm, it IS same pinout as PHR diode - floating case, same as all bluray and now apparently Blue diodes.

You are correct, I was looking at another diode

Thanks!

Default Re: ROUND 3 SOLD OUT!! - CHEAP 445nm (true blue) 5.6mm diode group buy.

Just a quick note for those who joined this GB.

Mine started to flicker at 2.23A, I have been running, stable, so far, at 1.73.

I do not have a LPM so I don't have the actual mW. Anyone in/near San Diego that could measure it for me?

Jose

Edit:
My readings need to be verified. I am using a microboost driver which has a max setting of 1A. I need to use a dummy load to verify my readings.
