Living Brightly on the Earth

Few things affect our moods and the beauty of our surroundings more than light.  Especially in the winter months, the lights we choose to vanquish the shadows of the early evening darkness are critical to living well, and for many of us, feeling happy. Luckily, LED lights, the most efficient lighting available, are getting better and better.


We’re used to the warm golden glow of incandescent bulbs, but they’ve been described as little heaters that happen to put out light. Incandescent bulbs burn out quickly and are inefficient energy users when compared to newer sources of lighting.  LED lights (Light Emitting Diodes) were first introduced six years ago, providing a greener option than compact flourescent lights (CFLs), which contain mercury.


The first generation of LEDS, though, cast a cool, bluish light, which was a problem for some consumers.  Thanks to recent developments in LED technology, the new bulbs produce a much warmer light, closer to the warmth of traditional incandescent bulbs. Lest you believe that LED lights can’t be beautiful, take a look at the glorious holiday light display at the famous Longwood Gardens in Delaware.  The Gardens converted to 100% LED lighting this year, and their Christmas event is more spectacular than ever.


Although LED lights are more expensive initially to purchase, they last significantly longer, in some cases, for as long as 20 years.  This makes them invaluable when placing them in hard to reach ceiling and recessed fixtures, and for commercial buildings and skyscrapers.  LED lights reach 80 % efficiency, which means 80% of the electrical energy is converted to light energy, with only 20% lost as heat energy.  Compare that with the incandescent bulb, which converts only 20% of the electrical energy to light energy, and loses 80% as heat energy.


Incandescent lights, contrary to rumors, will still be available, but the old 100 watt bulb is being replaced by 72 watt bulbs with the same light output and a longer life.  Whatever kind of lighting you prefer, energy efficiency has become a driving force in the industry. That’s good news for your home, your office, and the earth.
