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.
An average household spends about 5% of its energy budget to lighting. Switching to energy-efficient lighting is one of the easiest ways to cut the energy bills.
What is Color Rendering Index? The Color Rendering Index (CRI) is measuring the ability of a light source to stimulate the colors of various objects precisely along with the sunlight. Though there are critics of the subjective color used, the CRI is extensively utilized as a measurement of the quality of the light.
