An induction light is similar to a fluorescent light in that mercury in a gas fill inside the bulb is
excited, emitting UV radiation that in turn is converted into visible white light by the phosphor
coating on the bulb. 

Like fluorescent, the phosphor coating determines the color qualities of the
light.  Fluorescent lamps use electrodes to strike the arc and initiate the flow of current through
the lamp, which excites the gas fill.   Each time voltage is supplied by the ballast and the arc is
struck, the electrodes degrade a little, eventually causing the lamp to fail. induction lamps do not
use electrodes. Instead the system uses a high-frequency generator with a power
coupler.The generator produces a radio frequency magnetic field to excite gas fill.  

With no electrodes, the lamp lasts longer. Induction lamps, in fact, last up to 100,000 hours, much longer than metal halide (7,500 to 20,000) hours
