Historically, the old-fashioned incandescent bulb has been the most popular choice, not only because of the low price but also because of the soft white light. Both LED and incandescent bulbs turn on immediately without flickering. Compact fluorescent lights (CFLs) take time to warm up and can flicker. (Compact fluorescent lamps also contain a small amount of mercury.) Light-emitting diodes (LEDs) last between 20,000 and 50,000 hours, about five times longer than incandescent bulbs.
Cheaper than ever, LED light bulbs are gaining popularity in American homes. Not only do they save money on energy, but they also last much longer than traditional light bulbs and CFLs. Is it time to switch to LED?

How long does a light bulb last?
For comparison’s sake, let’s see how many bulbs you’d need for 25,000 hours of light. A 60W incandescent bulb can last 1,200 hours, which means you would need 21 bulbs to last 25,000 hours. An LED light bulb will use 10W, give off comparable light to a traditional 60W light bulb, but will last at least 25,000 hours and maybe more. Read on for a little estimate of how much you’d spend to buy an incandescent bulb compared to just an LED.
Environment and Sustainability
Even with the bulbs on, it is possible to reduce energy consumption with dimmers. Also, turning off the lights when you leave a room will lower your bills. And consider motion sensors or timers to keep outside lights on only when needed.
Guarantee
Create a leading manufacturer of LED bulbs, back your bulbs with warranty. On the Cree website, select the bulb to see the warranty policy for replacement or refund within ten years of purchase.
Tips for changing
Still, does it seem too much to change everything at once? Consider changing the light bulbs in the five rooms you use the most. Usually the lights in the kitchen, bedroom, bathroom, outside porch and living room are the most widely used. Use the lowest wattage that provides enough lighting. Make sure your LED light bulbs carry the EnergyStar label, which indicates independent testing and certification.
