NARROWBAND SPECTRA OF PHOSPHOR WHITE LEDS (3)


This web page will be for nothing but spectra of 10mm, 8mm, 5mm, 3mm, and SMD LEDS (driven at 20mA to 60mA; with the exception of the LED in the Motion-Sensing Spotlight):

Ocean Optics USB2000 Spectrometer donated by P.L.
As of 10-10-07, I've been using a PC2000-ISA Spectrometer from Ocean Optics that I received several years ago, but that I didn't have a home for until now.
As of 03-08-08, I once again have the USB2000 spectrometer, enabling color spectra again.
As of 09-19-09, I no longer have the PC2000-ISA; it was sold to prevent an eviction.
