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 03-08-08, 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.
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.
SUNLIGHT:
Spectrographic analysis of sunlight, 08-02-08 8:32am PDT in Sacramento CA. USA.
Taken without window glass, but through insect screen (not removeable).
As far as I'm able to determine, a CFL bub was on, which contaminated the July 30 and 31 spectra.
This time, I was ***CERTAIN*** to have all light sources deactivated to avoid contaminating the spectrum.
Spectrographic analysis of sunlight, 08-01-08 8:36am PDT in Sacramento CA. USA.
Taken without window glass, but through insect screen (not removeable).
Spectrometer's response narrowed to a range of 175nm to 384nm to show ultraviolet spectral features.
Spectrographic analysis of sunlight, 07-31-08 8:49am PDT in Sacramento CA. USA.
Taken without window glass, but through insect screen (not removeable).
Spectrographic analysis of sunlight, 07-30-08 8:29am PDT in Sacramento CA. USA.
Taken through window glass.
Spectrographic analysis of sunlight, 05-17-07 5:24pm PDT in Sacramento CA. USA.
Taken through window glass.
Spectrographic analysis of sunlight, 07-30-08 8:29am PDT in Sacramento CA. USA.
Taken through window glass.

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@gmail.com.
Please visit this web page for contact information.
Unsolicited flashlights, LEDs, and other products appearing in the mail are welcome, and it will automatically be assumed that you sent it in order to have it tested and evaluated for this site.
Be sure to include contact info or your company website's URL so visitors here will know where to purchase your product.
