Hey Kendall, i just got the PHR 803T diode in the Aixiz module from your website. I finished my first build with it and it works great, using a LM317T driver with a 10 ohm resistor and a 47 microfarad capacitor... So it should be putting out around 80 to 100 mW, i have no way of checking though... One quick question though:

In the Aixiz module i got, i took it apart and a little silver ring fell out. one side of this ring is slanted inwards, i was wondering where it goes... Then there was the spring in the back housing part, that i just took out because i don't have a driver in the back there...

Thanks!
