Out of all the different types of light bulbs available, not many bulbs come close in performance or efficiency to LEDs except compact fluorescent lamps (CFL). There are thousands of articles on the internet comparing the two lamps and advising consumers to buy one and or the other. You may be thinking, “Why is it even a question as to what lamp I’m going to pick up from the store? I know CFLs cost less than LEDs.” This is true, they do cost less initially, but we have a few reasons to steer consumers away from CFLs. Although the initial cost is less, the CFLs have to be replaced after a few years while LED lamps will need to be replaced every 10 years or so. We also do not support the fact that CFLs contain mercury, a harmful substance necessary for CFLs to produce light. LEDs produce a brighter, whiter light than CFLs without the use of this dangerous substance.
There are approximately five milligrams of mercury contained in each CFL. According to ENERGY STAR, some companies have lowered their mercury content to 1.4 – 2.5 milligrams per lamp. However, it doesn’t make the lamps any less dangerous. Here’s a scary thought: The incandescent lamp is going to be phased out over the next few years in the United States. When people go to shop for new light bulbs, more will choose CFLs. When the CFLs reach the end of their lifespan, most people will toss them in their trashcan instead of recycling them at a certified mercury disposal location. The CFL lamps are glass, and will break either during transport to a landfill or in the garbage truck. Garbage truck drivers and maintenance personnel will be exposed to the mercury, along with the soil and water at the landfill. If one billion CFLs have been disposed of in this year alone, think about how many will be disposed of in upcoming years and what that means for the future of the environment.
Even if we can’t make people stop buying compact fluorescent lamps, we hope they will dispose of them at facilities that specialize in mercury disposal. Paying a little more upfront for LED lamps will not only save you money in the long run, but it will also save the environment.
