About LED's

  • Light Emitting Diodes have been available for over thirty years.
  • LED's are the dominant lighting systems for indication and panel display. High Brightness LED's are rapidly gaining market share for area illumination.
  • LED's are all around you - torches, signage, indicators, car brake lights
  • Specialist suppliers, such as Constellation Lighting, have now developed high power lighting able to illuminate large areas in workplaces, retail, and streets.
  • LED's consume much less power than other types of light
  • LED sources are small and directional - unlike large halogen, florescent or incandescent lamps - the light goes where you want it.
  • LED's are solid state devices - there is nothing to suffer from shock or vibration
  • LED's can be tuned to provide different wavelengths of light. This allows a much more natural spectrum of light than other types of lamp with a positive effect on human reaction (Maas, Jayson, Kleiber - Effects of spectral differences in illumination on fatigue) (Blackwell - Effects of light source spectral distribution upon visual functions)
  • LED's typically last up to 100,000 hours. A typical incandescent lamp for less than 1000 hours and a compact florescent lamp 10,000 hours - much lower maintenance costs.
  • LED's are flicker free - tests have shown that fluorescent lights with conventional ballast increase the rate of errors administrative tasks (Rey & Rey Comparison of the effects of two fluorescent lights on visual tasks and fatigue tests)
    LED's will cold start instantly - cold stores and warehouses are lit instantly so lights can be switched off in periods of inactivity without loss.
  • LED's appear to help with health and fatigue compared to many fluorescent lights (Wilkins, Nimmo-smith, Slater, Bedocs - Fluorescent lighting headaches and eye-strain)
