उत्तर
LED is a solid-state light source.
- Energy efficient: More light output for lesser electrical power. LEDs are now capable of producing 135 lumens/watt.
- Long Lifetime: 50,000 hours or more if properly manufactured.
- Rugged: LEDs are also called Solid State Lights (SSL) as they are made of solid material with no filament or tube or bulb to break.
- Excellent colour rendering: Colours produced by LED do not fade out, making them perfect for displays and retail applications.
