In the earlier edition of “Green Wednesdays”, we talked about how energy efficient and cost effective compact florescent lights (CFL) are than the incandescent bulbs. CFLs are the most commonly used alternative to bulbs. Now there is a new possible option in the domestic market; Light Emitting Diode (LED).
LEDs are energy efficient light bulbs and their use was limited to single bulb use in instrument panels, pens, decoration etc. It was then clustered together and initially was used as head lamps and flashlights.
LEDs are solid bulbs so they last longer and are more durable than CFLs and their life span is almost 10 times than that of CFLs. LEDs also reduce the air conditioning cost as they do not build up heat when lit. Another advantage of LED is that there is no mercury used in its production. LEDs also make solar panels more practical because of their less power consumption.
LEDs unlike CFLs do not consume any warm-up time to come to full brightness. Also the initial cost of LED is more than that of CFL, but they last much longer than the CFL. That way the consumer makes up for the initial cost over the lifetime of LED.
