SPECTRA OF CCFT LAMPS


This web page will be for nothing but spectra of CCFT (Cold Cathode Fluorescent Tube) lamps:

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.

CCFT LAMPS:

Spectrographic analysis
Spectrographic analysis of the CCFT in the Energizer® Arc White LED & CCFT Flashlight; newest spectrometer software settings used.


Spectrographic analysis
Spectrographic analysis of the CCFT in the Energizer® Arc White LED & CCFT Flashlight (newest spectrometer software settings used); spectrometer's response narrowed to a band between 175nm and 379nm to show UV spectral features.

CCFTs (Cold Cathode Fluorescent Tubes)

Spectrographic analysis
Spectrographic analysis of the UVC Tube and PSU.


Spectrographic analysis
Spectrographic analysis of the UVC Tube and PSU; spectrometer's response band narrowed to a range of 250nm to 260nm to show the 253.7nm mercury line.


Spectrographic analysis
Spectrographic analysis of the UVC Tube and PSU; spectrometer's response band narrowed to a range of 179nm to 384nm and deliberately "overexposed" to show alternate UV spectral lines.


Spectrographic analysis
Spectrographic analysis of the UVC CCFT in the HygeniClean UVC Anti-Bacterial Light Wand.

Spectrometer's input deliberately "overloaded" to show weaker spectral lines.


Spectrographic analysis
Spectrographic analysis of the UVC CCFT in the Mini Disinfecting UV Scanner.


Spectrographic analysis
Same as above; spectrometer's response band narrowed to a range of 250nm to 260nm.



Spectrographic analysis
Same as above; spectrometer's response band narrowed to a range of 175nm to 380nm
and deliberately "overexposed" to show weaker UV spectral lines.


Spectrographic analysis
Spectrometer's response band narrowed to a range of 180nm to 230nm.
This shows that there is *SOME* emission at "vaccum UV" wavelengths; responsible for producing ozone.
Baseline was artificially lowered with Photoshop.

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.
