What Is The Difference Between CFL And LED Light Bulbs?

Over the years, technological advances have brought in advancements in how to light our homes and commercial buildings. All we had at first was the normal, incandescent light bulb. We now have compact fluorescent lamps (CFL) for short, and light-emitting diodes or LEDs. We will answer the issue… which sort of light bulb reigns supreme? There's a lot of reason to consider, so let's dive in!

LED VS CFL Brightness

Were LED lights better than or equivalent to Compact Fluorescent bulbs (CFL)? The challenge is to get the application to understand. In short, LED and CFL as systems do not necessarily vary in brightness. Lumens determine luminosity. The best term for lumens is the measurement of light. A single CFL and LED bulb may have the same lumen (brightness) output but the amount of energy required to produce that degree of brightness varies greatly.

In the past, several LED bulbs were not omnidirectional which gave CFL the upper hand during different scenarios. For example, a CFL would perform better in a floor lamp, because the light range was much wider at the time. However, the LED would have greater effectiveness in most recessed lighting (ceiling). Fast forward to new generations of LEDs and we see the small light-emitting diodes beating CFLs in overall energy usage, color and becoming even more competitively priced on the market.

Lumen & Wattage Comparison

You need to learn about lumens, to compare different light bulbs. Lumens, not watts, tell you how bright a bulb is, no matter what kind of light it is. The more lumens, the brighter the light. Labels on the front of light bulb packages now state a bulb’s brightness in lumens, instead of the bulb’s energy usage in watts. Simply find the lumen output you are looking for when searching for your next light bulb (the bigger the brighter) and choose the lowest wattage bulb (the lower the better).

Do CFL or LED bulbs last longer?

Quick Answer: LED

While LED technology for use in bulbs hasn't been on the market for a long time, the new technology's lifetime predictions are impressive and leave CFL and incandescent with little to show for in contrast. LED light bulbs are the undisputed, heavyweight longevity king with an impressive lifetime of 25,000 hours. The next best are CFL bulbs that carry an average life expectancy of acceptable 8,000 hours. Keep in mind that most experiments are based on a runtime of three hours per day.


In every way, the LED is better than CFL. The LED saves up to 80 percent of the electricity bill even if its output is much lower. It is recyclable, and its brightness remains the same, even after long use of it. The frequent on / off switch did not reduce their lifespan, either. Although the CFL saves up to 70 percent of energy costs. And it is not recyclable so it contains mercury which has adverse human consequences. CFL costs are also very high, and can only be used for 6000-10,000 hours.
