CFLs vs LEDs
BENEFITS for the environment: LEDs are significantly more energy efficient than both incandescent light bulbs and CFLs, which reduces their carbon footprint on the environment. Also, unlike CFLs, LEDs don't have any mercury, so there is no risk of pollution and contamination of water, fish, and food supplies.1
BENEFITS for your wallet: Because LEDs are actually about 20-50 times as efficient as incandescent light bulbs, they can save you many times more money on your electrical bill than CFLs in the long run.2
BENEFITS for you: Many people are wary of using CFLs because of their mercury content, however this is a non-issue with LEDs! CFLs must be disposed of carefully if not recycled, and you can read more about disposal options in the Greeniacs Guide to CFLs . Although CFLs don't usually pose a health hazard, if they happen to break, you might be susceptible to mercury exposure if you are not careful.3
Replacing a simple 25 watt incandescent with an LED bulb can cost around $40.4 However, a recent breakthrough in the production of LEDs may bring down the price of LEDs to the level of CFLs within a couple of years. So for only a few more dollars than incandescent bulbs, LEDs should be coming our way shortly!5
Time and Effort: Low
Switching to LEDs is literally as easy as changing a light bulb. LED arrays can fit into standard light bulb sockets, replacing your incandescent bulb.6 You can find LEDs at your local stores, chain stores such as Target, and online.
How to choose between CFLs and LEDs:
Generally, LEDs are significantly more energy efficient, durable, and long-lasting than CFLs, making them even more friendly for the environment than CFLs. However, there are two major drawbacks. First, they cost significantly more than CFLs. Secondly, the light is much more directional and focused, limiting it as a valid replacement for diffused lighting. Here is a chart-to-chart comparison of their respective characteristics:
