Advantages of LED bulb | Disadvantages of LED bulb
This page covers advantages and disadvantages of LED bulb. It mentions LED bulb advantages and LED bulb disadvantages.
The LED (Light Emitting Diode) is semiconductor device which does conversion of electricity into light. LED bulbs are better to produce light in single direction compare to incandescent bulbs or fluorescent bulbs.
Advantages of LED Bulb
Following are the advantages of LED Bulb:
➨LED lights are rugged and damage resistant compare to fluorescent/incandescent bulb types.
➨The use of LED bulb incurs lower cost on long run due to its long life, low maintenance cost and energy savings.
➨LED bulb does not use mercury. It is environmental friendly as it generates lower heat. Moreover it can be recycled. LED bulbs do not use any hazardous materials, it do not generate any hazardous waste.
➨LED lighting does not emits UV or infrared rays. Hence this light is harmless light.
➨It can be controlled in full range e.g. dimmable, warm white, natural white and cool white.
➨High quality light distribution can be achieved using LED lighting.
➨LED lights can be switched on with almost zero delay compare to filament based lighting.
➨LED bulbs can be designed into different shapes and sizes.
➨LED bulbs produce almost no heat and hence one can save on air conditioners.
➨LED bulbs do not flicker and hence do not cause any RF interference and hence it is easier to the eyes.
Disadvantages of LED Bulb
Following are the disadvantages of LED Bulb:
➨It is more expensive compare to incandescent lights during initial purchase.
➨It shifts color due to aging and temperature variation.
➨It must be powered with correct voltage and current at constant flow.
➨It is restricted by the technology.
➨It causes backward heat dissipation towards emitter.
