SPECTROGRAPHIC (NORMAL & NARROWBAND) AND POWER OUTPUT ANALYSES OF LEDs THAT KLAATU SENT IN LATE-MARCH 2013 (1)
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 (1):
All spectra were performed with an If (forward current) of 330mA.

Beam terminus photograph of a high-powered royal blue LED (442nm) from an unknown OEM.
That pinkish color is because my camera doesn't "do" pure or nearly pure blue very well.

Epistar chip
Notes:
1) All leads are reversed, minus sign is stamped on anode instead of cathode;
2) All leads are the wrong kind, they are short and stick straight out so can't be reflow soldered to the boards. Original listing picture showed normal leads.
3) 29 of 40 have solder on the leads, and are clearly used, not new.
4) All of the LEDs with solder are dead.
5) The remaining 11 leds are new and work, but have the wrong leads and they are on backwards.
6) After purchase received and vendor contacted, she changed the picture in the listing to show the clipped leads, and promised to make & send new beads with proper leads.
7) Can see tiny zener diode inside bead next to led chip
