LED bulb vs CFL bulb :- which more Energy Efficient?

Confused about choosing between CFL bulbs vs. LED bulbs? Since 2014, government regulations have been pushing consumers to replace familiar incandescent light bulbs with more energy-efficient compact fluorescent lamp (CFL) and light-emitting diode (LED) bulbs. Advances in both CFL and LED technologies have expanded consumer choice — yet make evaluating your options a little more complex. Knowing how different kinds of light bulbs stack up against each other will help you not only get the right lighting for any given space but also save energy in the process. CFL vs. LED bulbs In the CFL vs. LED battle for energy efficiency, life span and cost, the winner is the LED bulb. We’ve come a long way in energy-efficient light bulb technology. While incandescent bulbs remain on the market for now, the benefits of newer technology are driving the switch to LED bulbs. To understand the advantages of LED bulbs vs. CFL, or even incandescents, it helps to know a little bit about how they work. In an incandescent bulb, electricity passes through a filament that gets so hot that it produces light. About 95% of the energy is wasted as heat, with only 5% of it going toward light. How much heat do CFL and LED bulbs give off? LED efficiency is best because the bulbs waste very little energy on heat, concentrating electricity on the production of light. Incandescents waste the most energy. CFLs are not all that much better, releasing 80% as heat. LED or CFL: Which bulbs last longer? LED bulbs last longer than CFL bulbs. With 25,000 or more hours of life, an LED handily beats the CFL bulb’s and incandescent bulb’s averages of 8,000 hours and 1,200 hours, respectively. Comparing CFL vs. LED bulbs, LEDs last much longer. https://blog.constellation.com/2016/03/25/led-vs-cfl-bulbs/
