LED Bulb vs. CFL Bulb: Know the Difference
By Shumaila Saeed || Published on January 15, 2024
LED Bulb uses light-emitting diodes to produce light, known for energy efficiency and long lifespan. CFL Bulb (Compact Fluorescent Lamp) uses fluorescent technology, more efficient than incandescent but less than LED.
Key Differences
LED Bulbs use light-emitting diodes, which offer high energy efficiency and long life. CFL Bulbs use a small amount of mercury vapor that emits ultraviolet light when electrified, then fluoresces to produce visible light.
