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. Smiley

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.

interesting. I still have and use a 'flip'phone, It just makes phone calls and crappy pictures. There is an APP in Florida tied to the parking meters. You can pay through the phone, It will also let you know when time is running out. Maybe time for me to get a 'smart' phone

It's looking like Facebook and mobile apps are killing forums and smaller websites. I don't think it's just flashlights.

light-reviews and custom light factory look to be among the missing. Has the internet traffic really slowed down a lot for the remaining flashlight sites?
