The U.S. Department of Energy on Tuesday said it was raising energy efficiency standards for light bulbs, giving manufacturers 75 days to phase out incandescents before an outright ban in July 2023.
Haitz's Law, was conceived by Dr. Roland Haitz, states that every 10 years the cost per lumen falls by a factor of 10, while the amount of light generated per LED package increases by a factor of 20.
In 1962, Nick Holonyak, Jr. (the “Father of the Light-Emitting Diode”) invented the first LED that produced visible, red light while working at General Electric.
The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura "for the invention of efficient blue light-emitting diodes which have enabled bright and energy-saving white light sources."
Did you know even though more efficient than incandescents, disposing of fluorescent tube lights is bad for the environment because they contain mercury?
#GoLED
Now more than ever I love promoting brands that design with an eco-conscience and love for life + the planet. By promoting brands like Varaluz I am inspired to echo the feeling these lighting pieces evoke by creating vibrant and artistic art campaigns. #varaluz#lighting#banana
