LED vs CFL -- Which Light Bulb is More Efficient? | CleanTechnica

LED vs CFL -- Which Light Bulb is More Efficient? | CleanTechnica: "When comparing the two on paper, the efficiency of the bulbs is nearly identical, within 0.5 lumens per watt. However, with the “real world” being taken into consideration, there are certain environmental and consumer factors that make a case for both.

One factor is cost. If your primary concern is price, the CFL would be a better choice. Although the CFL has a shorter lifespan, even if you replaced the CFL three times to achieve an equivalent lifespan to the LED, you’d still have only spent $2.58 in comparison to the LED’s $45 initial purchase price.

Another factor is location. If the fixture you’re mounting the bulb in is in a place where it’s a hassle to change, that $40 difference might be worth not having to deal with it for the expected 20+ years of normal usage you’ll get out of the single LED.

The bottom line is that in a household setting, where optimal components and ideal conditions cannot be controlled,  the LED and CFL light bulb are very close competitors. The decision for one over the other should be made based on the goals of the project and you may even require a mix of technologies to meet those goals."
