Question to you guys that like to push their diodes hard... I ordered a diode whose seller says it's 2.2V nominal... (808nm / 300mW eBay special, my fingers are crossed that it works at all) Do you guys think I'm safe using a typical 3V supply (eg. LM1117 base), or do I have to design a lower voltage one? Just increase my load-series resistor a bit?
