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 03-08-07, I once again have the USB2000 spectrometer, enabling color spectra again.

SPECIAL COLOR LEDS:

Spectrographic analysis of a Nichia NCCL023 warm white LED; circa. December 2004.

Spectrographic analysis of the warm white high-powered LED in the Motion-Sensing Spotlight.

Spectrographic analysis of a Roithner Lasertechnik 5R4HCA-PH phosphor pink LED.

Spectrographic analysis of a Nichia NSPY500S phosphor yellow LED.

Spectrographic analysis of the phosphor purple LED in the Rainbow In My Room.

Spectrographic analysis of the LEDs in the Pink LED Scrolling Dog Tag.
Plot is low because there is no way to get any of the LEDs to operate in constant-on mode.

Second spectrographic analysis of a 10mm phosphor pink LED in a module from American Technical Services.
It has visibly degraded to a more-or-less white color in just a matter of hours.

Spectrographic analysis of the pink LED in a multicolor LED module from American Technical Services.

Spectrographic analysis of a phosphor pink LED from American Technical Services.
This is after ~60 hours of continuous operation at 28.1mA;
this tells me that the phosphor is inorganic in composition.

Spectrographic analysis of a warm white LED from American Technical Services.

Spectrographic analysis of a phosphor pink LED from American Technical Services.

Spectrographic analysis of a nonphosphor white LED (see directly below) at ~1.8mA (***NOT*** the 2004 version!).
The LED appeared more yellowish than it did at ~20mA, so I ran a second spectrographic analysis of it.

Spectrographic analysis of a nonphosphor white LED from LEDSales.au (http://www.ledsales.com.au...).

Spectrographic analysis of the purple LEDs in the LED ''SIGNS'' Sign.

Spectrographic analysis of the fuchsia LED in the LED 6-Light Necklace.
This LED is flashing, not steady, so I was unable to obtain a full-height spectrum of it.

Spectrographic analysis of an unknown-type 5mm pink LED.

Spectrographic analysis of a LEDTronics # L200-TPP-180D pink LED.

Spectrographic analysis of the yellow LEDs in the LumaRay FL6 Fog.

Spectrographic analysis of the blue-green LEDs in the LumaRay FL12RX Fog.

Spectrographic analysis of the yellow LEDs in the LumaRay FL12RX Fog.

Spectrographic analysis of a phosphor pink LED (Roithner Lasertechnik # 5R4HCA-PH).

Spectrographic analysis of a phosphor purple LED (ETG-5AX420-15).

A 5mm stable phosphor pink LED, Roithner # 5R4HCA-PH.

Zinc Selenide (ZnSe) non-phosphor white LED.

Stable phosphor-type pink LED.

Stable phosphor-type purple LED.

Spectrographic analysis of a yellow Nichia NSPY500S LED.
