SPECTROGRAPHIC (NORMAL & NARROWBAND) AND POWER OUTPUT ANALYSES OF LEDs THAT KLAATU SENT IN LATE-MARCH 2013 (2)
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. 
SPECTRA (NORMAL & NARROWBAND) OF LEDs THAT KLAATU SENT IN LATE-MARCH 2013 (2):
All spectra were performed with an If (forward current) of 330mA.
This is the high-powered (1 watt) 655nm red LED from an unknown OEM.
