Induction lighting is in many ways similar to fluorescent lighting. It differs however in a number of key areas. Both Induction and fluorescent lighting consist of a tube filled with gases and a small amount of mercury; with fluorescent lighting the mercury is in liquid form however in Induction the mercury is in a solid amalgam which makes recovery during recycling a much easier process.
In Induction the gas/mercury mix is then excited using magnetic coils rather than a filament as used in fluorescent lighting, this is what gives the Induction is remarkable longevity – generally 100,000 hours or nearly 12 years continuous running. The filament is the weak point in fluorescent lighting, every time you turn the lights on this filament rapidly heats up and just like in an incandescent light the filament eventually fails. Without the need for a filament the Induction light doesn’t suffer from this weakness.
This process generates Ultraviolet light which is then passed through a phosphor coating on the tube and is converted in to light in the visible spectrum. The phosphor coating can be varied to give different shades or colours of white light which can be tailored to the environment in which the lights are installed.
With such longevity Induction lighting is well suited to installation in areas that are out of reach of an easy lamp change. Warehouses, factories, street lights, supermarkets, swimming pools, sports halls, large out of town shops and really anywhere with a high ceiling or anywhere that needs security in the operation of their lighting – there is nothing worse than failed lights ruining the look of your shop or hindering staff in production or warehousing when you know it will take a major operation to replace even one lamp.
As Induction lighting also has a very low failure rate – top Induction light units have an early life failure rate of virtually 0% when compared to rival technologies such as LED which can have an early life failure rate as high as 10% this is vitally important – it is safe to install it in areas that are difficult to access or that would involve a major interruption to operations too.
Induction light isn’t for everywhere, the light units (or lumenaires) themselves are quite large and so there is little place for them in the domestic environment. Also the lower power units can be less efficient. Aside from these two caveats everyone should take Induction lighting technology in to consideration when selecting their lighting.
