The Evolution of Lighting (Exclusive Video)
August 8th, 2014 by Zachary Shahan
I think the video below is my last video from this year’s Abu Dhabi Sustainability Week* that I have to share, which is good, because we’re more than halfway between this year’s Abu Dhabi Sustainability Week and next year’s!
This video below is from a tour of GE’s first (and currently only) Ecomagination Center, which is located in Masdar City. This is just one short segment on lighting, but I thought some of the facts were interesting enough for a share.
- In the video, it’s stated that 80 watts can produce electricity for 2 incandescent bulbs or 8 LEDs. However, 40-watt equivalent LEDs from Cree actually use just 6 watts, and reportedly produce more light than a 40-watt incandescent, so 80 watts could produce electricity for 13 such bulbs and more light generated.
- According to one of the screens on that display, 82% of the 2 billion light bulbs sold globally every year are incandescents. Imagine the energy savings that is possible from switching to LEDs! (And note that LEDs are now cost-effective on a lifetime basis, often saving consumers a ton of money by the time they die out.)
- On the same screen, GE points out that ~80% of an incandescent bulb’s energy use goes toward the creation of heat, while ~80% of an LED’s energy use goes toward the creation of light.
It’s time to move beyond incandescents (and CFLs) to LEDs — plain and simple.
