Induction Lights consist of two main components: a ballast and a sealed, gas-filled bulb. Light is produced via electromagnetic induction, without an electrode or any electrical connection inside the bulb. Instead, high frequency electromagnetic fields are induced from outside the sealed chamber.
Because there is no fragile electrode burning within, lamp life expectancy is increased to 100,000 hours - over 500% longer than standard HID and fluorescent technology. *
To produce light, the ballast supplies the electric coils with high frequency electrical current.
The ferrite magnets on either side of the bulb then emit electromagnetic fields which excite electrons within the bulb.
As the electrons accelerate inside the bulb, they collide with mercury atoms and produce ultraviolet (UV) light radiation.
The UV light then causes the special phosphor coating inside the glass to react in a way that produces fluorescent light within the visible spectrum.
The light produced by Induction Lighting achieves a rating of 85 on the Colour Rendering Index (CRI), with a Correlated Colour Temperature of 2700-6500K.**
*Based on a conservative HID lamp lifetime 11,000 hours
**CCT and CRI may vary by individual product.
