Guys hello,

which diode of two is more popular beam quality wise?
PLP520-B1 osram vs. Sharp GH0521DE2G

Also i have seen dtr oberdriving osram diode up to 480mA.
Does same apply for the sharp diode too?

Thank you

No, I wouldn't drive the Sharp diode that hard. I personally drive them at 280 mA. You'll get better than 100 mW out at that current. Actually, much more.

So is osram more overdrive friendly? What about beam? Which one is more nice?
