SPECTROGRAPHIC (NORMAL & NARROWBAND) AND POWER OUTPUT ANALYSES OF LEDs THAT M.B. SENT IN LATE-JULY 2012 (1)



This web page will be for nothing but spectra of the high-powered LEDs that M.B. sent in late-July 2012:

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.

SPECTROGRAPHIC (NORMAL & NARROWBAND) AND POWER OUTPUT ANALYSES OF LEDs THAT M.B. SENT IN LATE-JULY 2012 (1):

All spectra were performed with an If (forward current) of 347.120mA.

The chart starts to fall off not because the LED became a DED (Dark-Emitting Diode), but because I pressed the wrong key on the keyboard when I attempted to perform a screen dump and then neutralised the power supply because I do not have a heatsink for the LED.
