These days everyone is talking about how to save the environment: recycle more, use less water, energy-efficient appliances, the list could really go on and on. Here are a few ways you can have your cake and eat it too- i.e save money on your electric bill, and help the environment.
No toxic chemicals
LEDs, as most know, don't contain any harmful chemicals such as mercury or gases. This in itself makes them not only less dangerous if one breaks, but also very easy to recycle.
Longer light life
LEDs last much longer than traditional lights (fluorescents, metal halides, etc). Because they have a long life it's going to incur less waste in the long run, and a lot of the LED lights can be repaired to an extent (either replacing the driver or the LED strip), depending on what style of LED light you have.
LEDs draw much less power than traditional lighting, which is why we get that lower electric bill whenever they're used. This, in turn, eliminates greenhouse gases given off by the power plant, and your electric company may actually give you a rebate whenever you initially purchase an LED light- this can help to alleviate any startup costs.
Fewer lights needed
Most LEDs don't have0-degree beam pattern like most fluorescents, they usually have about a 180-degree beam angle, which gets more of your light shining downward. You actually need fewer lights to get a lumen equivalency to that of fluorescents, which in turn equals less waste in the long run.
Next time you think about converting to LEDs, realize that it will not only give you a much cleaner, uniform light, it will also help reduce your carbon footprint.
