Benefits and Drawbacks of LEDs

November 19, 2015

LEDs offer a huge variety of benefits but at the same time they cannot be viewed as the optimum solution for every lighting-related application. Here, in no particular order, we list some of the main advantages of LEDs, together with some of the challenges faced by these devices.

  • Lifetime
    As solid-state light sources, LEDs have very long lifetimes and are generally very robust.
  • Standardization
    Various standards relating to LEDs exist in areas such as automotive lighting and traffic signals.
  • Low maintenance
    The long lifetime of LEDs reduces the need to replace failed lamps, and this can lead to significant savings, particularly in the cost of sending out maintenance crews.
  • Efficiency
    White LEDs with efficacies of 25 lm/W and up are commercially available, exceeding the performance of incandescent and some fluorescent sources.
  • Low power consumption
    The low power consumption of LEDs leads to significant energy savings that can often drive the installation of LED-based systems.
  • Brightness
    Although LEDs have high efficiency and consume a small amount of power, the devices produce a small total number of lumens.
  • Heat
    LEDs don't produce heat in the form of infrared radiation, which makes incandescent bulbs hot to the touch.
  • Cost
    LED manufacturers continue to work towards reducing their production costs while at the same time increasing the light output of their devices.
  • Small form-factors
    LEDs are very small - typical high-brightness LED chips measure 0.3 mm by 0.3 mm, while high-power devices can be 1 mm x 1 mm or larger.
  • Instantaneous switch-on
    LEDs switch on rapidly, even when cold, and this is a particular advantage for certain applications such as vehicle brake lights.
