REQUESTED BY MIKE P. FROM ILLINOIS
This web page is for spectra of LEDs and two low-voltage incandescent halogen light blubs requested by Mike P. from Illinois USA in late-February 2011.
The ultimate purpose of these analyses is so that Mike can calibrate his own spectrometer.
All of the lamps are "loaners" and have to be returned when testing is complete, so additional testing and analyses of them will not be possible.
I use the USB2000 Spectrometer, and all LEDs have an If=19.280mA..
INCANDESCENT 12 VOLT BROAD-SPECTRUM HALOGEN LIGHT BULBS
LED 1.16 -- Tungsten Halogen Lamp, 20 watt incandescent lamp w/ G4 bi-pin base.
Vf= 12.030 volts; If= 1.522 amps.
Sylvania tungsten halogen quartz 12v 10W incandescent lamp w/ G4 bi-pin base.
Vf= 12.080 volts; If= 0.869 amps.
LEDS

NOTE THAT ALL NIR LEDS WITH PEAK WAVELENGTHS EXCEEDING
1,000nm HAVE NO "TAIL" VISIBLE AT SHORTER WAVELENGTHS;
THAT'S WHY THE FIVE (5) ABOVE CHARTS APPEAR BLANK!!!
