A Light Emitting Diode (LED) is a semi-conductor light source and increasingly being used in general lights due to several advantages it carries over conventional lighting.
The longer life of an LED with reduced maintenance cost makes it a preferred selection for various lighting requirements. The LEDs can be smaller than 2 mm and are more energy efficient. The LEDs can are very durable and can sustain extremely high or cold temperatures.
LED lights save upto 80% of the power usage compared to the conventional lights. LED lights last more than 21 times compared to incandescent lights and 3 times compared to CFL lights. LED provides instant lighting and frequent switching with zero UV emission.
LED bulbs uses only 3 to 7 watts compared to fluorescent bulbs that uses 20 to 35 watts. Also LED tubes use only 16 to 25 watts compared to fluorescent tubes that consume 45 to 100 watts..
