LEDs are more energy efficient, durable, versatile & long lasting compared to CFLs. (i)Average life span of LED lamps (50,000 h) is more than that of CFLs (8000 h). (ii)LEDs use less power (watt) per unit of light generated (lumen). To generate 450 lumen, LEDs consume least energy (4-5W) than CFLs (9-13W). Hence, LEDs are more economical than CFLs over the whole life span.
