LEDs are lighter and use less electricity for the same light output - 85% less electricity when compared to conventional lighting and around 18% less electricity compared to CFL.
Typically LED lamps have a lifetime of 50,000 hours. Conventional bulbs last around 1,000 hours and CFL around 5,000 hours. Switching to LED will save you time and money on replacement lamps and maintenance.
LEDs use less electricity and emit less heat. This means decrease in CO2 emissions from the LEDs and from a 40% reduction in electricity used by HVAC systems. LEDs also don't contain harmful mercury that CFLs contain.
Less energy used → greater electricity savings.
While some argue the higher initial cost of LED bulbs isn’t worth the cost savings in reduced energy use, time and again studies have illustrated the return on investment is recovered quickly
