NARROWBAND SPECTRA OF LOW-POWERED BLUE LEDs (NEWEST {03-25-12 and 01-13-13} SPECTROMETER SOFTWARE SETTINGS USED) (PG. 2)


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 BLUE LEDs (NEWEST {03-25-12 and 01-13-13} SPECTROMETER SOFTWARE SETTINGS USED)

Spectrographic analysis
Spectrographic analysis of the blue LEDs on the undercarriage of the UDI U818A 2.4GHz 4-Ch. 6-Axis Gyro R/C Quadcopter w/ Camera; spectrometer's response narrowed to a band between 450nm and 460nm to pinpoint emission peak wavelength, which is 453.290nm.

The raw spectrometer data (tab-delimited that can be loaded into Excel) is at http://ledmuseum.candlepower.us/47/droneb.txt


Spectrographic analysis
Spectrographic analysis of the blue LED on the Syma Armor F1 Single-Rotor R/C Helicopter (with Li:Poly battery's Tx; spectrometer's response narrowed to a band between 455nm and 465nm to pinpoint emission peak wavelength, which is 460.340nm.

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 Color-Changing Twister Lights 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 Color-Changing Twister Light.
