- Light emitting diodes – LEDs are solid state semiconductor lights - A proven technology since 1962
- LEDs are used worldwide for both general purpose and special purpose lighting
- Efficiency: LEDs does not waste Input electrical energy to generate heat unlike Bulbs that convert 98% energy into heat & thus prevents Global Warming.
- Cool light: Due to high CDR (Color Rendering) & wide spectrum of wave lengths
- Reduces Green House gases: Lower consumption of energy results in less burning of fossil fuels resulting in lower contribution to Green House Gas effects.
- LED is the cost effective green lighting solution that is maintenance friendly, weather resistant, and pays for itself in less than 5000 hrs of usage or within 7 months of continuous use
- Longer Lifetime: LEDs unlike Incandescent or Fluorescent bulbs have a longer life time of more than 12 Years or 50,000 burning hours.
- Shock resistant: Total Solid state bulbs and does not contain fragile filament or moving parts.
- Environment friendly: Does not contain any toxic materials like Mercury, does not contribute to Global Warming which is need of the day.
