LED Technology

What do we know about LED and what are its benefits?

  • LED lights have 10 times higher efficiency (luminosity/output) than light bulbs and two times higher efficiency than fluor tubes (the most advanced ones over 100 lm/W) which is particulary effective in the devices supplied by batteries or energy-efficient lamps.
  • Can deliver light in a required colour without using complicated colour filters
  • A LED light cover can be designed to focus light to a certain spot. Light bulbs and fluorescent tubes do usually need outer optical scheme to focus light.
  • At the facilities where light dimming is needed, LED lights stay the same colour after the power supply has been lowered, unlike classic light bulbs which give off a slighly more yellow light after dimmed.
  • Is resistant to tremors and vibrations
  • Is resistant to cold weathers
  • Is ideal to make use of at those facilities where lights are turned on and off frequently unlike regular light bulbs especially flood lights which are prone to explosion when turned on and off too often. Fluor tubes are even more sensitive to this which can lead to overheating of one of the filaments
  • The benefits from its lifespan are, as argued by LED manufacturers, between 100 000 and 1 000 000 hours (doesn´t apply to high-power LED whose values drop considerably). The lifespan of fluor tubes and light bulbs is from 6 000 to 12 000 hours and 1 000 to 2 000 respectively.
  • The often seen cause of failure of LED lights is a steady decrease in brightness unlike light bulbs which over time are subject to a filament snap.
  • It only takes a short while for the light to go on. A typical LED indicator light starts glowing in the time frame of microseconds. The time needed for LED lights to go on especially at telecommunication facilities is even shorter.
  • The LED lights are conveniently small and can be planted onto printed circuit boards.
  • Do not contain mercury (unlike lamps).
