This web page will be for nothing but spectra of various artificial and natural light sources other than LEDs and lasers - they have their own web pages here.
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.
I have been asked on a number of occasions to furnish a spectrum of sunlight; where I'm at that is simply not possible.
Not unfiltered sunlight at noon near summer solstice anyway.

Spectrum of an incandescent lamp filtered with Coherent argon
laser safety goggles; advertised as "OD 5 at 515nm and below".
HID LAMPS:
Spectrographic analysis of the HID bulb in the Polarion Helios PF40 HID Searchlight; "overexposed" to show weaker spectral lines.
Spectrographic analysis of the HID bulb in the Polarion Helios PF40 HID Searchlight.
Spectrographic analysis of a Power On Board HID Spotlight
Spectrographic analysis of a Power On Board HID Spotlight,
deliberately "overexposed" to show weaker spectral lines.
Spectrum of a Light Cannon 100 HID, normal.
Spectrum of a Light Cannon 100 HID, overdone to show weaker spectral lines.
GLOW LAMPS:
White neon bulb (neon & xenon gas fill).
NE-2G greeen neon lamp assembly (neon & krypton gas fill).
This is the lamp assembly from Radio Shack; it is in a transparent green housing.
NE-2G greeen neon bulb (neon & xenon gas fill).
NE-2 neon bulb.
NE-2 Mini neon bulb.
NE-2H neon bulb.
NE-2 neon bulb that may also contain krypton gas.
Neon figural glow bulb with phosphor.
GE AR-1 argon glow bulb.
Neon glow bulb.
EL (ELECTROLUMINISCENT):
Spectrographic analysis of a green electroluminiscent nightlight, GE brand.
Plot is so low because the intensity of the generated light is so low.
OTHER:
Spectrographic analysis of a HPS (high pressure sodium) lamp approximately 100' away.
Spectrum taken through window glass and a plastic positive (magnifying) lens.
Plot is low because I was unable to expose the spectrometer's sensor to sufficient radiation from the lamp.

Spectrum of the white on a 19" Sony CRT boob-tube computer monitor.
Spectrum of the white on the LCD screen of a Nikon Coolpix 775 digital camera.
Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at ledmuseum@worldnet.att.net or send your potential victim to:
