Understanding Kelvin and LED Light Color Temperatures
experimental physics - How could I measure the colour spectrum of a light bulb and investigate how closely it matches a black body radiation curve? - Physics Stack Exchange
electromagnetic radiation - Why does the LED light colour spectrum spike in the blue and green wavelengths but CFL lights have lots of smaller spikes across a few wavelengths? - Physics Stack Exchange
Ultimate Light Bulb Test - Incandescent vs. Compact Fluorescent vs. LED
