I made a new power supply for my LEDs, and wanted to test it out so here are the results of that test:

Power supply: Old Zip drive/ITE/ Input-120vac 60Hz 0.3A Output- 5vdc 1A

Buck puck- LED driver module - 5-14vdc input 1000mA

400nm UV high pwr LED 3.5vdc 350mA/ Prolight 470nm Blue high pwr LED 3.5vdc 700mA/ Cree 623nm Red high pwr LED 2.7vdc 700mA/ Cree





Below is the graphical representation of all 3 LEDs


These are the associated calibration curves for all 3 LEDs

Hey @d4mo, no, I use a version I modified, Plab v2.5 spectrometer kit. you can check it out here:

I have been asking people using the Plab 3.0 to do the same thing I am doing but no one has stepped up to the plate yet!
