"Good things come in small packages" is how the old saying goes; I wonder if that applies to weird packages too? You might ask yourself, "What exactly is an LED bulb and why does it have such an odd name" as you reach for the same incandescent bulb your great grandparents used to buy like two hundred years ago (just kidding, the incandescent bulb was patented by Alexander Nikolayevich Lodygin in 1874). Grandpappy was a smart man, so if it worked for him it works for me, right?
Well wake up, times they are a changing. They split the atom, landed on the moon, deciphered the human gene code, and eliminated poverty—well they're still working on that last one. Another one they're working on is saving our planet from becoming an ever-lasting waste pile of humanity, and these "weird" little LED bulbs are a giant step in the right direction.
A light-emitting diode (LED) is extremely small, consumes little energy and contains no lead or mercury, making it quite environmentally friendly. LED's emit light when connected in a circuit, with a semi-conductor chip that has two regions filled with positive and negative electric charges serving as the nuts and bolts.
LED bulbs last 15 years or longer, aren't toxic and use something like 90% less energy than their predecessors. This is really a no-brainer, and the boys at Commerce Energy figured out a way to make it easy by offering the bulbs on their website. The Commerce Energy bulb base comes in both a screw and pin design, making it easy to switch out old incandescent or halogen bulbs. What does this mean for you the consumer? It means more money in your pocket and less destruction to our precious environment, considering about 10% of all home energy costs come from lighting. For once, you can give your pocket and our environment a break at the same time.
P.S. You should still turn the light off when you leave the room!
