Advantages of LEDs & Technology Comparison

Energy efficiency: LED based devices are highly energy efficient. Most of LED devices save up to 70% electricity in comparison to conventional lighting device.


Maintenance free: LED have an average lifespan of 1, 00,000 hrs i.e. more than 10 -12 years of continuous operations.


Low power dissipation: LED devices offer high-energy efficiency and thus emit very less energy in form of heat dissipation, compared to conventional lighting devices.


Eco-friendly product: LED products are not dangerous to health and environment as they do not contain any hazardous or poisonous substances and hence there is no problem of their safe disposal. They also help in meeting the LEEDS certification for green buildings.


Similar to sunlight: LEDs emit frequencies that are closest in range to normal sunlight. In addition , there are no harmful UV/IR radiations from LEDs, making them safe to be used by humans. LED lights can also be used to grow plants in indoor applications, as they promote photosynthesis just like sunlight.


Size: LEDs can be very small (smaller than 2 mm2) and are easily populated onto printed circuit boards.


Other advantages There are also many other advantages offered by LEDs e.g. they offer high color rendition, better image capture and flicker free lighting.
