A hybrid fluorescent lamp technology that eliminates the need for electrodes and filaments; generating light by means of a high frequency transmission of energy combined into a gas discharge.
As with conventional fluorescent lamps, varying the composition of the phosphors coated onto the inside of induction lamps, allows for models with different color temperatures. Unlike conventional fluorescent technology there are no failures caused by filament erosion, vibration, or seal breach.

External magnetic induction lamps are essentially fluorescent lamps with electromagnets wrapped around a section of the lamp tube.  High frequency energy, from the electronic ballast (generator), is sent through wires, which are wrapped in a coil around the ferrite inductor, creating a powerful magnet.

The induction coil produces a very strong magnetic field which travels through the glass and excites the mercury atoms in the interior which are provided by a pellet of amalgam (a solid form of mercury). The mercury atoms emit UV light and, just as in a fluorescent tube, the UV light is up-converted to visible light by the phosphor coating on the inside of the tube. The system can be considered as a type of transformer where the inductor is the primary coil while the mercury atoms within the envelope/tube form a single-turn secondary coil.

In a variation of this technology, Internal magnetic induction lamps use a light bulb shaped glass lamp, which has a test-tube like re-entrant central cavity. This cavity is coated with phosphors on the interior, filled with inert gas and a pellet of mercury amalgam. The induction coil is wound around a ferrite shaft which is inserted into the central test-tube like cavity. The inductor is excited by high frequency energy provided by an external electronic ballast (generator) causing a magnetic field to penetrate the glass and excite the mercury atoms, which emit UV light, that is converted to visible light by the phosphor coating.

External induction lamps manage heat either by convection through the air or conduction into the fixture. HighHorse internal induction lamps operate with a higher internal temperature and must cool by conduction to the base heat sink and by radiation through the glass walls. With both lamp types a small percentage of mercury ions are absorbed by the phosphor coating over time; once the mercury ions inside the envelope are depleted, the lamp emits only a very dim light and has to be replaced.
HighHorse Electronic Ballasts (generators) are warranted for five years. (Actual life expectancy can be significantly longer with proper thermal management.)
