Light-emitting diode (LED) lights is the perfect substitution to conventional "halogen" light bulbs [50 watts] as they consume only 20% of electricity as compared to its peers i.e. 80% energy savings, less heat emission - less air conditioning, longer lifetime, improved robustness, smaller size and faster switching on/off.
Applications of LEDs are diverse. They are used as low-energy [8 watts] and also for replacements for traditional light sources in well-established applications such as indicators / signage ( in airports, railway stations etc. ) and automotive lighting. The Nintendo Wii's sensor bar uses infrared LEDs as well as TVs and VCRs remote controllers.
The compact size of LEDs has allowed new text and video displays and sensors to be developed, while their high switching rates are useful in communications technology and red LED lights accelerate plant growth ( photosynthesis ) during autumn especially for strawberry plants in greenhouses.
