The accepted view of how to utilise the resources of our planet is evolving, fortunately technology is able to provide solutions to some of the problems. It has become generally accepted that incandescent lighting is inefficient and out of date; we believe that the same is true of the current types of fluorescent lights (particularly CFL) and metal-halide lights that are now in use and paradoxically may even be promoted as environmentally friendly. We distribute three types of lighting technology; LED, Induction and Plasma, they all offer significant improvement in; power consumption, use of environmentally harmful materials and overall cost of operation (Total Cost of Ownership), however it is important to apply each technology in accordance with its optimum characteristics.
Induction Lighting The latest generation of external inductor lamps resemble fluorescent lamps with electromagnets around a part of the tube. High frequency energy, from electronic ballast, passes through wires in a coil around a ferrite inductor on the outside of the glass tube, creating a strong magnetic field which travels through the glass and excites the atoms of the material inside. The excited atoms emit UV light and, just as in a fluorescent tube, the UV light is converted to visible light by the phosphor coating on the inside of the tube. The glass walls of the lamp prevent the emission of the UV light as ordinary glass blocks UV radiation. The internal materials have developed in line with metal halide and florescent technologies but where the move to reduce mercury content further reduces the life of conventional lamps due to electrode burnout; induction lights with no internal electrodes maintain extremely long life (~100,000 hrs.). The long service life proportionally reduces the consumption of harmful materials, furthermore induction lights do not require a warm up period, they are dimmable and can even be adapted to operate at temperatures below minus 35°C. The design flexibility of induction lighting is limited and they are most efficient for medium to high power installations (80W to 300W); with lower power efficiency (~90 lm/W), lower initial cost and longer service life than LED; induction lighting can be the technology of choice for simple applications like High Bay lighting for factory units and other high level indoor, or outdoor mounting such as car park lights.
