Turn the lights on, let them warm up for a few seconds, and point the spectrometer sensor cable at the desired light. Set the spectrometer to a boxcar setting of about 100. A broad Black Body radiation curve can then be seen. The peak of that curve will shift to different wavelengths as you look at the different Kelvin rated bulbs.
