Induction Lighting

Induction lighting is very similar to a fluorescent lamp in that it uses the excitement of mercury gas to emit UV radiation that in turn is converted into visible light by the phosphor coating on the bulb.

Fluorescent lamps, however, use electrodes inside the bulb to strike the arc and initiate the flow of current – each time the arc is struck, the electrodes degrade a little, eventually causing the filaments to burn and the tube to ultimately fail.

Induction Lamps differ in that they do not use internal electrodes, but use a high-frequency electronic ballast with a magnetic ferrous coupling ring surrounding the tube on two ends. When the ballast starts it sends a magnetic field directly through the 100% sealed fluorescent tube exciting the gases and generating the UV energy that is converted to visible light.

With no electrodes, the lamp lasts  up to 100,000 hours, with the lamp producing 70% of its original light output up to 70,000 hours.In other words, their rated life is 5-7 times longer than metal halide (7,500 to 20,000 hours at 10 hours/start) and about seven times longer than T12HO fluorescent (at 10 hours/start).
