led-chipLEDs (Light-Emitting Diode) have a unique method of creating light. When an electric current is passed through an LED, electrons recombine with electron holes within the device and release photons (light) through a process called electroluminescence. This allows LEDs to be smaller, more robust, consume less energy and have a longer lifetime than legacy lighting systems. While low power LEDs have been used in displays and other similar applications for years, high powered LEDs capable of illuminating a room are a much more recent development.

Typically, a single diode is incapable of providing the same illumination as an incandescent or fluorescent light. Additionally, since the diodes are a point source of light, they emit a focused beam of light in a single direction within a very narrow angle. Therefore, LED lamps are composed of multiple diodes arranged in an array to increase the level and angle of illumination.

These LED arrays are highly energy efficient, achieving from 70 to 90 lumens per watt. However, grouping LEDs causes heat to build so heat dissipation must be taken into consideration. In ideal settings, LEDs have demonstrated lifetimes of 50,000 hours, a marked improvement over the 15,000 hour rating of metal halides or 2,000 hour ratings of incandescent. However, heat will drastically shorten the life of the diodes and the internal control chip, making LEDs suited for indoor applications with minimal temperature variance.  Due to their point source nature, LEDs are commonly used as accent lighting. Used to emphasize, they make colors appear more vibrant and life-like.

The Benefits of LED Lighting:

  • Efficiency – 60-70% more efficient than legacy lighting systems. – Significant reduction in utility bills, continuous savings.  – Minimal energy wasted as heat.
  • 50,000 hours Lamp Life – Good for more than 10 years! (based on 12hrs/365 days) – Greatly reduces bulb replacement costs and maintenance fees.
  • Instant On, Instant Re-Strike – Immediate illumination from the moment you flip the switch. – Unlike legacy lighting systems, LEDs do not degrade when switch on and off multiple times.
  • Excellent Lumen Maintenance – Retains 80% of luminosity at 40,000 hours. – Legacy lighting systems begin to dim from the moment you plug them in.
  • Eco-Friendly – 70-90 Lumens per Watt means less energy used for an equal level of illumination. – energy consumed results in a smaller carbon footprint.  – Longer bulb life results in fewer replacement bulbs in landfills.  – Lamps run cooler than legacy lighting systems, reducing the demand on the AC system.  – No harmful mercury used in lamp
  • Solid State Lighting – Extremely robust and resistant to shocks
  • Superior Accentuation – Point light source makes desired areas “come to life” – Higher color temperature more closely resembles daylight at noon.  – Makes merchandise more vibrant and appealing.

Applications:
Mostly indoor applications, especially suited for accent lighting and lighting solutions that require frequent switching.
