NARROWBAND SPECTRA OF LOW-POWERED YELLOW-GREEN LEDs (NEWEST {03-25-12} SPECTROMETER SOFTWARE SETTINGS USED)


This web page will be for nothing but spectra of 10mm, 8mm, 5mm, 3mm, and SMD LEDS (driven at 20mA to 60mA):

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.



NARROWBAND SPECTRA OF YELLOW-GREEN LEDs (NEWEST {03-25-12} SPECTROMETER SOFTWARE SETTINGS USED)

Spectrographic analysis
Spectrographic analysis of the backlighting LEDs in the WeatherTech FX5000 Weather Forecaster; spectrometer's response narrowed to a band between 540nm and 580nm to pinpoint peak wavelength, which is 568.509nm.

Radiation level was ***FAR*** too low to get decent spectrographic analyses, but here "ya" go anyway.


Spectrographic analysis
Spectrographic analysis of the yellow-green "Charge cycle in progress" LED in the Nikon Coolpix S4300 Digital Camera; spectrometer's response narrowed to a band between 560nm and 580nm to pinpoint peak wavelength, which is 569.577nm.


Spectrographic analysis
Spectrographic analysis of the yellow-green "Power" LED in the Nikon Coolpix S4300 Digital Camera; spectrometer's response narrowed to a band between 560nm and 580nm to pinpoint peak wavelength, which is 574.296nm.


Spectrographic analysis
Spectrographic analysis of the yellow-green "Charge cycle in progress" LED on the radio of the Tuffoam™ Fun Flyer ''Park Flyer'' R/C Airplane.; spectrometer's response narrowed to a band between 540nm and 590nm to pinpoint peak wavelength, which is 559.927nm.


Spectrographic analysis
Spectrographic analysis of the yellow-green LEDs ringing the base of the Star Trek: The Next Generation Medical Scanner Stage Prop; spectrometer's response narrowed to a band between 550nm and 570nm to pinpoint peak wavelength, which is 557.618nm.


Spectrographic analysis
Spectrographic analysis of the yellow-green LEDs in the control panel of the Quickie® Pulse 6 Electric Wheelchair; spectrometer's response narrowed to a band between 550nm and 590nm to pinpoint peak wavelength, which is 570.333nm.










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.
