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.
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.

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.
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.
