LED Better 300x199 The Difference Between LEDs and CFLs: Efficiency
This is the first post in a brand new series about the key differences between compact fluorescent lamps (CFLs), the light source of the present, and light emitting diodes (LEDs), the light source of the future. We’ll touch on things like structure, function, and quality, so you can keep up with all the innovations currently happening in the lighting world…

One of the most obvious differences between LED light bulbs and CFLs is energy-efficiency. Yes, we consider both sources to be energy-saving, and both fall well within new government efficiency standards, but it’s a simple fact that LEDs use less power to generate more light.

We measure the efficiency of a light source (sometimes called efficacy) in lumens per watt (lm/W). If you’re unfamiliar with this measurement, we’re just talking about the amount of light produced by one unit of electrical power – similar to miles per gallon for a car.

In general, a good LED on the market today can produce 60-100+ lm/W, which is about twice as many as a CFL, which only produces about 30-50 lm/W. 

However, LED innovation isn’t over. Given the astounding progress LED technology has made over recent years, the U.S. Department of Energy believes that we could see solid state LEDs attain an efficacy of at least 200 lm/W in the future.

What does this mean for you? Simply put: Your energy bills will be lower when you use LED light bulbs.

Stay tuned to explore more facets of LEDs and CFLs with us!
