How Does Induction Lamp Work?
Induction lamps are basically a type of fluorescent tube. The main difference between a fluorescent tube and an induction lamp is that the tube is completely ‘sealed’. There is no filament inside the tube.
Our lamps are ‘external inductor’ lamps, which means that the lamps have an electromagnet wrapped round part of the tube. This electromagnet produces a very strong magnetic field that passes through the glass and causes the light to be emitted.
In conventional gas discharge lamps, the electrodes are the part with the shortest life, limiting the lifespan severely. Because Induction lamps don’t have electrodes, they can have a very long service life.

Our induction lamps – which have separate ballasts – have an expected service life of between 75,000 and 100,000 hours.
The Induction lamps are ‘instant on’ and ‘hot strike’, which makes them ideal for use with sensors.
Because there are no electrodes, the Induction lamps handle vibration far better than conventional gas discharge lamps. This makes them ideal for use in car parks and for high - level external lighting in areas susceptible to wind.
Another benefit of induction lights is the low lumen depreciation. Lumen loss in a conventional discharge lamp can be considerable as the filament is ‘used up’. There are no filaments inside an induction lamp, so the lumen loss is minimal over the operating lifetime of the lamp.
Our Induction light fixtures are energy efficient. They enjoy a high power factor, typically between 0.95 and 0.98. The energy conversion efficiency is also very high. Typically the conversion efficiency is between 62 and 90 lumens per watt, with the higher output lamps being more efficient.
One of the benefits of this efficiency is the relatively low level of energy lost to heat output. Our Induction lamp retrofit run ‘cool’ minimizing the damage caused to the lamp housing, the wiring and the lens itself.
We believe that Induction lighting is a very effective, energy efficient lighting source, but don’t take our word for it. Here’s what the inventor, Nikola Tesla thought:
"Surely, my system is more important than the incandescent lamp, which is but one of the known electric illuminating devices and admittedly not the best. Although greatly improved through chemical and metallurgical advances and skill of artisans it is still inefficient, and the glaring filament emits hurtful rays responsible for millions of bald heads and spoiled eyes. In my opinion, it will soon be superseded by the electrodeless vacuum tube which I brought out thirty-eight years ago, a lamp much more economical and yielding a light of indescribable beauty and softness."
