When it comes to outdoor lighting, LED technology is more effective and energy-efficient than all of its competitors.
Read on to find out why.

Nowadays, LED lighting solutions outperform all traditional sources on the global outdoor lighting market. And rightly so: let’s have a look at all the major advantages of LED technology.

The 6 main advantages of LED lighting

  1. Adaptable​ 
    • LEDs have a Color Rendering Index (CRI) from 70 (cold white) to 80 (warm), even 90.
    • LEDs emit a saturated colour palette, offering pure and deep hues.
    • LEDs allow the white colour temperature to be chosen (from 2200K to 10000K). 
    • LEDs facilitate trichromy and quadrichromy.
  2. Versatile
    • LEDs are instantaneous: they emit 100% of their flux as soon as they are turned on. This allows for instant operation of installations (no warm-up time), as well as light effects such as flashes and strobes. 
    • LEDs are dimmable from 0 to 100%: dimming and fading across the entire colour spectrum is possible when combined with intensity controllers, motion detectors and time switches. 
    • LEDs are focusable: their beam can be orientated and focused as needed using adapted optics.  
    • LEDs are modular and adjustable: innovative designs thanks to the fact they are small, come in an array of shapes and capacities, and can be used alone or in a group.
  3. Powerful
    • LEDs can achieve luminous flux of 160 to 200 lm/W. 
    • LEDs’ flux can be regulated between 0 and 100%.
    • Coloured LEDs do not require a colour filter which absorbs part of the flux.
  4. Economical
    • LEDs have outstanding lifespans of over 50,000 hours, at which point they still emit 70% of their original flux. Correctly used, an LED in operation 4 hours a day will have a 70% flux after 35 years! LEDs are extremely robust, and resistant to shocks, vibrations and travel.
    • Les LED sont d’une robustesse à toute épreuve, très résistantes aux chocs, déplacements et vibrations. 
    • LEDs minimise service downtime and replacement costs. They are thus suitable for difficult-to-access structures such as bridges and building façades.
  5. Safe
    • LEDs eliminate fire risks because they emit little infrared radiation and give off little heat.
    • LEDs reduce electrocution risks because they often use low-voltage power.
  6. Eco-friendly
    • LEDs emit no harmful electromagnetic waves, nor UV rays.
    • LEDs help cut electricity consumption.
    • LED reduce light pollution caused by outdoor lighting.

The drawbacks of LED technology

Certain precautions must be observed in order to take full advantage of the advantages of LED technology.

  • LEDs must be protected from humidity by watertight casings.
  • LEDs are sensitive to high temperatures, controlling their temperature is vital to maintaining their flux and lifespan.
  • LEDs are sensitive to overvoltage and static electricity.
  • LEDs are more difficult to install in 360°lighting installations.

So LED lighting may require a bit of care and attention, but these disadvantages are greatly outweighed by the many advantages that pave the way for a bright future of innovation, energy savings and sustainable development.
