Why LEDs

Why LEDs

Solid-state lighting ( the LED technology ) is increasingly used in a variety of lighting applications because it offers many benefits, including
Long life — LEDs can provide 50,000 hours or more of life, which can reduce maintenance costs. In comparison, an incandescent light bulb lasts approximately 1,000 hours.
Energy savings — The best commercial white LED lighting systems provide more than twice the luminous efficacy (lumens per watt) of incandescent lighting. Colored LEDs are especially advantageous for colored lighting applications because filters are not needed.
Better quality light output — LEDs have minimum ultraviolet and infrared radiation.
Intrinsically safe — LED systems are low voltage and are generally cool to the the touch.
Smaller flexible light fixtures — The small size of LEDs makes them useful for lighting tight spaces.
Durable — LEDs have no filament to break and can withstand vibrations.

According to the U.S. Department of Energy, in the next 20 years, rapid adoption of LED lighting in the U.S. can :
- Reduce electricity demands from lighting by 62%
- Eliminate 258 Millions metric tons of carbon emissions
- Avoid building 133 new power plants
- Anticipate financial saving that could exceed $115 Billion

Performance Comparison
Delivered Lumens Per Watt
When you average delivered lumens over a course of 60,000 hours, LED outperforms a 400-watt MH lamp operated in a horizontal position. (60,000 hours is used for this comparison to show three full life cycles of the HID.)

 Lumen depreciation of the MH lamp, as well as optical and ballast losses, reduces output of the HID system. The MH lamp will also require three re-lamps over 60,000 hours.

The best LED technology offers significantly better lumen maintenance, a more efficient driver and don't need re-lamping within 60,000 hours. Combine this with our superior technology and LED outperforms MH over the course of the life of the fixture.
