Light-Emitting Diode (LED)

A light-emitting diode is a semiconductor light source that emits light when voltage is applied and current flows through it.

The technology is nothing new, it has been around for over 50 years. The recent development of white LEDs is what has brought it into the public eye as a replacement for other light sources due to their efficiency and longevity.

 

 Benefits of LEDs:

  • LED light fixtures are the most versatile and energy-efficient choice for lighting.

  • Durable and shockproof unlike glass bulb lamps.

  • Lowest energy consumption rate compared to any other lighting technology.

  • Rated lifespan expected to exceed 50,000 hours.

  • Very little lumen depreciation over their rated life-span.

  • Long-term maintenance savings: bulb replacement, labour & lifting equipment hire can come with significant costs.

  • Produce far less heat than other fixture, lessening the demand on cooling systems.

  • LEDs are directional, useful in applications where reducing light pollution is required.

Lumen depreciation

When people think of the lifetime duration of various lighting technologies, they typically do not take lumen maintenance into consideration. All lighting technologies have a rated life expectancy; however, the amount of useful light output varies depending on their respective lumen maintenance curve. LED lighting product lifetimes are rated at an L70 value, meaning that once the light output is at 70% of its initial output it is considered at the end of its life. The rated lifetimes for many legacy lighting products are listed as when they fail to emit light or when a portion of the population fails to emit light. This is a significant difference between traditional lighting and LED lighting rated lifetime.

A typical Metal Halide bulb may be rated to last for 20,000 hours, but when measured using the methods defined in the TM-21 standard to determine the L70 value, the amount of usable light is only useful within the first 8,000 hours. Thereafter, the lamps will produce a dull-yellow light, below the Lux requirements of a workplace. Fluorescent lighting presents a better lifetime curve; however, due to hard failures and rapid lumen degradation, it falls off significantly at 20,000 hrs.

When considering a building with many fixtures and bulbs, maintenance of traditional fixtures becomes both labour-intensive and very time consuming, especially when adhering to-rated lifetimes. To effectively manage current lighting, maintenance personnel need to keep track of when products were installed, estimate burn out periods, when to order more, in addition to the valuable time spent replacing them. Many go without changing bulbs that are at the end of their lumen maintenance curve and consequently light levels within the facility suffer. This suppresses worker productivity and efficiency and can compromise the safety standards of the work environment.
