Life of LED
It is calculated that LED chips will give a long life up to 150000 hrs compared to 10,000 hrs of CFL and 1000 Hrs of Incandescent bulbs. But the life of LED s is dependent on the make of LED, thermal management of the LED fixture and LED driver life. If anything of above said is not matching the criteria for good performance of LED chips and according to the specs given by the manufacturer, the LED's life drastically reduce even if it offer a very long life in the datasheets.
Long life of the LED light engines means you don't need to replace a LED light for 17 Years even if you are using it for 24 Hrs a day. So there is no burden of replacing the damaged products and you can save money buying new products for replacing damaged one and also maintenance costs will be very low.
LEDs uses 50-70% less power compared to conventional luminaries. One should be very careful in choosing LED light engines to achieve the above said. Since the LEDs are available offering 30-160 Lm/W, the customer should select atleast 105 Lm/W LED to achieve an equivalent performance of CFLs which offer 60 Lm/W . Since the LEDs are directional and radiating in a narrow beam angle, say 120 Degree it will create more impact on performance compared to conventional fittings which is radiating in 360 Degree where there is a loss caused by the reflector or shade we use integrated with the light engines.
Customers should also choose a good quality driver having higher energy efficiency and power factor, built in with long lasting electronic components to enjoy the max power saving and long life.
Moreover LEDs contains no toxic substances like Mercury which is there in CFLs, disposal of these light engines have a lesser impact on the environment.
