The LED bulbs last longer and therefore will save you time and money in the long run. CFL’s use 25-35% less energy than traditional light bulbs, or incandescent bulbs, use. LED’s, on the other hand, use 75% less of the energy than incandescent bulbs use. This means that LED bulbs are incredibly energy efficient.
Are all spiral light bulbs CFL?
CFLs typically use 50-80 percent less energy and last up to 10 times longer. In this installment of the Light Bulb Shape Guide, we’ll be covering the most popular CFL bulb, the spiral.

Can you replace CFL with LED?

Which is brighter CFL or LED?
CFL’s or fluorescent light bulbs emit 60 lumens per watt. LED’s, however, are the most effective of all, with a whopping 72 lumens per watt. This means that for around 10 watts of power, an LED will be just as bright as a 60-watt bulb.

CFLs are up to four times more efficient than incandescent bulbs. You can replace a 100-watt incandescent bulb with a 22-watt CFL and get the same amount of light. CFLs use 50- to 80-percent less energy than incandescent lights. Just one bulb can reduce a half-ton of CO2 from the atmosphere over the life of the bulb.
