Spectrographic analyses of lights & products which use them

ICON Solo Flashlight






(Maximum intensity); spectrometer's response narrowed to a band between 430nm and 470nm to pinpoint native emission peak wavelength, which is 446.957nm.

Note if you will, that minimum and maximum intensity modes show virtually the same native emission peak wavelength; this is a direct result of PWM which effectively eliminates current-related wavelength shift -- and hence, perceived LED color.

Direct sunlight, 08-12-12 at 7:09am PDT in Federal Way WA. USA.


Taken without window glass, but through insect screen (not removeable).
The sun was very low on the horizon, that's why spectral features in the blue, violet, NUV, and ultraviolet are attenuated or missing altogether.

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.

Mini LED Guide Light






Spectrometer's response narrowed to a band between 440nm and 470nm to pinpoint native emission peak wavelength, which is 451.898nm.

I had to partially disembowel the product (to expose the LED) in order to obtain this spectrum and the one directly above; the unit was successfully reassembled after the analyses.

In-Cabinet Light






Spectrometer's response narrowed to a band between 440nm and 470nm to pinpoint native emission peak wavelength, which is 451.898nm.

In-Cabinet Light






Spectrometer's response narrowed to a band between 570nm and 600nm to pinpoint phosphor peak peak wavelength, which is 451.898nm.

Deck Marker Light






Spectrometer's response narrowed to a band between 450nm and 480nm to pinpoint native emission peak wavelength, which is 465.888nm.

I had to completely disembowel the unit (in order to expose the LED to my spectrometer) to obtain these spectra; it is otherwise too dim for this instrument. I successfully reassembled it after performing these analyses so, "no harm no foul" as they say.

Last 10 Shouts: SPAM Hey - time to make a little noise around here SHOUT ! ! ! ! ! ! ! ! ! ! ! !   will Time for the Monthly Shout Out. Hello....   fatlight Thanks for the welcome back folks. I missed the forum. Seems like the Dr. has got a pretty good handle on what my trouble is. A large part of my having good health is going to be up to me. Diabetes I can help myself with. The others well............. gearhounds Wow! That's messed up! Just goes to prove that even with advanced medicine, we can't figure out everything right away lawallac FL glad to see you back.  Best wishes and good health to everyone!   will Wish there was an edit button should read fatlight, not fatalight   will fatalight - wow - glad you are on the mend. post as often as you want to. For sure, we do not mind. stay healthy !!!!!!!! fatlight I hope to start participating again if that's o.k. with the forum. I am glad to be alive. I will probably be getting the antibody infusions for the rest of my life. Anyway, it is good to feel like participating again if yall don't mind. fatlight My Dad has passed on and they figured out my trouble so I get infusions of the antibody I need and I have started to feel a lot better in the last two weeks. fatlight and because of that I caught a every bug you can think of. Ended up in the hospital a couple times and was honestly at the point of death until they figured out what was happening to me.
