What is an LED?

An LED (Light Emitting Diode) is a semiconductor material (made up from the III-V elements in the Periodic Table) that generates light when an electric field is applied across it, as shown in Figure 1

How Do LEDs Work?

At the positive-negative junction the compound semiconductor gallium nitride converts electrical energy straight into blue light. The blue light of the diode comes up against luminescent colored particles, which turn it into yellow light, as shown in Figure 2.

The mixture of these blue and yellow colors produce the desired color appearance, white, which can be used for general-purpose lighting.

Why LED Lamps & Bulbs Over Other Technologies?

  • Greater Savings!
  • With LED bulbs, you can save up to 84% in energy consumption compared to the standard bulbs they replace.

  • Warm & Inviting Light!
  • LED light sources bring out the best in your home décor. LED bulbs turn on instantly and are flicker-free.

  • Long life!
  • LED retrofit bulbs are rated for up to 50,000 hours. That means they last as long as 50 standard incandescent bulbs or 5 compact fluorescent bulbs. They’re ideal for hard-to-reach locations and fixtures that are on for long periods of time.

  • Sturdy & Reliable Design!
  • Their sturdy design makes them easy for you to handle and they are more resistant to temperature fluctuations.

    In addition, LEDs are a versatile option for any direct replacement in your home. Plus, they are dimmable!

  • Environmentally Smart choice!
  • LED bulbs are environmentally preferable products and can help reduce your home’s carbon footprint. Due to their long life, each LED bulb keeps 50 incandescent or 5 compact fluorescent bulbs out of the landfills.

Where Can LED Lamps & Bulbs Be Used?

LED medium based lamps are a direct replacement for standard incandescent, halogen, and CFLi lamps. Use them in table lamps, ceiling fixtures, track lighting, vanities, sconces, ceiling fans and outdoor security lamps.
