CFL vs LED light bulbs: which is better? Compact fluorescent lamps (CFLs) are a version of the long tube fluorescent lights. They use less electricity than the traditional light bulbs. Moreover, an ENERGY STAR-rated CFL uses about one-fourth of the energy and lasts longer than a traditional incandescent that puts out the same amount of light. It contains mercury, which is a toxic heavy metal, which is harmful to both health and the environment.
How a LED works? The LED is an electronic light source that works by the effect of the electroluminescence. When a semi-conductor diode is turned on, the electrons recombine with the holes, and the energy is discharged as light.
Retractable cords allow you to use one light more efficiently if you need more illumination without needing to use other recessed or ambient lighting at the same time. You may also want white LED lights for brightness and to save on energy costs.
