It provides higher performance and energy-efficient white light for indoor and exterior application areas.
Mr Sheard said orange (sodium) lights "intimidate" people and the council hopes to replace 5,000 of these with more energy-efficient white lights, which have the added bonus of reducing light pollution.
To the chagrin of efficiency advocates, it seems that nearly everybody who pulled out the avocado-colored 1970's refrigerator and replaced it with a sleek, new, energy-efficient white-on-white model kept the old one, too.
The atlas also projects what would happen if all outdoor lighting in Europe switched from common high-pressure sodium lights to energy efficient 4000-K white light-emitting dioed (LED) lights.
Government supporters point out a number of initiatives in less than two years, despite the economic crisis, including £3bn for the Green Investment Bank, a carbon price floor to boost clean industries, tough new carbon emissions targets, the Green Deal to make homes more energy efficient, and the first natural environment white paper for over 20 years.
Summer is when new roofs are installed and old ones are redone, but contrary to news articles and experts touting the benefits of white reflective roofs, the fact is that my home city of Seattle and most northern cities in the U.S. waste millions in energy costs and precious natural resources by buying into the myth that white roofs are energy efficient regardless of climate zone.
The advantage of this approach is that blue LEDs are the brightest, most energy-efficient kind.Existing white LEDs are also based on blue ones, the light from which is used to excite a phosphor layer made of yttrium aluminium garnet (YAG).
OLED's give off a white light that is less harsh, more uniform and more energy efficient than fluorescent light, and is said to be the closest simulation of actual sunlight.
Cheap and efficient white light-emitting diodes (LEDs) are of great interest due to the energy crisis all over the world.
"We can make cars more energy efficient.
