SPECTRA OF UVC FLUORESCENT LIGHT BULBS


This web page will be for nothing but spectra of UVC fluorescent light bulbs.
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.


Spectrographic analysis
Broadband spectrographic analysis of the UVC fluoro tube in the AquaStar Plus™ UV Spectracidal Water Purifier; yet newer software & settings used.


Spectrographic analysis
Narrowband spectrographic analysis of the UVC fluoro tube in the AquaStar Plus™ UV Spectracidal Water Purifier; yet newer software & settings used.
Spectrometer's response narrowed to a band between 175nm and 379nm (UV radiation only) and deliberately "overloaded" to allow weaker UV spectral features to be seen.


Spectrographic analysis
Spectrographic analysis of the UVC fluoro tube in the UVC + Incandescent Lamp. Newer spectrometer software & settings used.


Spectrographic analysis
Spectrographic analysis of the UVC fluoro tube in the UVC + Incandescent Lamp; spectrometer's response band narrowed to a range of 250nm to 260nm to show the 253.7nm mercury line. Newer spectrometer software & settings used.


Spectrographic analysis
Spectrographic analysis of the UVC fluoro tube in the UVC + Incandescent Lamp; spectrometer's response band narrowed to a range of 179nm to 379nm and deliberately "overexposed" to show alternate UV spectral lines. Newer spectrometer software & settings used.


Spectrographic plot
Spectrographic analysis of the incandescent portion of this product.


Spectrographic analysis
Same as above; newer spectrometer software & settings used. Spectrographic analysis
Spectrographic analysis of the UVC CCFT in the HygeniClean UVC Antibacterial Light Wand; plastic cover left in place to show that it really does absorb harmful UVC radiation.


Spectrographic analysis
Spectrographic analysis of the UVC CCFT in the HygeniClean UVC Antibacterial Light Wand; spectrometer's input deliberately "overloaded" to show UV emission lines. Plastic cover left in place to show that it really does absorb the deadly UVC radiation.


Spectrographic analysis
Spectrographic analysis of the UVC fluoro tube in the UV Spectracidal Water Purifier; bottle left in place to show that harmful UVC radiation is indeed filtered out by it.


Spectrographic analysis
Spectrographic analysis of the UVC Tube and PSU.

This shows that there is *SOME* emission at "vaccum UV" wavelengths; responsible for producing ozone.

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.
