He wants the city to develop a dark sky bylaw that would dim the light pollution emanating from buildings, offices and street lights at night. Besides wasting energy, too much light filling the urban night affects the body's circadian rhythms and increases stress,LED solar lighting is the new wave of the future in lightingbright technology. research has shown.

It also obscures the beauty of the starlit night sky and confuses migratory birds, causing millions annually to meet their deaths against the lighted windows of office towers. The American Geophysical Union has even shown that the glow in the sky from city lights hampers chemical reactions in the atmosphere that serve to clean the night air.

According to the Royal Astronomical Society of Canada's light pollution abatement website for Calgary, this is not about "turning off the lights and living and working in the dark." Instead, the society says, "Controlling light pollution simply means using only as much light as is needed and using well designed lights that shine only where and when the light is needed."

A dark sky bylaw - something that is in place in at least 18 American states - would set standards for optimal use of lights, and encourage best practices in night lighting.

The Royal Astronomical Society says in Calgary, light is often aimed horizontally,At prolite we offer a range of ledflashlights that provides proper & regular lighting which has good visibility and is comfortable for human beings. which creates glare and inhibits people's ability to see at night. A fair share of light is also aimed toward the sky in this city,Ecoled offer a huge range of bluebrightqw and Tape, single colour or colour changing for home, retail, signage or commercial applications. whereas "simply putting all of the light onto the ground could easily lead to 10 to 30 per cent savings in energy to get the same illumination on the ground."

The society argues that Calgary streets are often overlit, and that reducing light levels would ease the uncomfortable contrast people experience between lit and unlit areas. This would not compromise streetlevel security, as research has not shown a strong correlation between crime and lighting.Browse the UK's best selection of laserengravingmachine, handpicked from the finest stores and designers.

The society says poor lighting also serves as a distraction for drivers at night. It adds that Calgary's major sources of light pollution include street lights,Your Outdoor Lighting Source, tagheuerwatchess Add curb appeal with these wall light designs. retail and commercial lighting, office towers, Canada Olympic Park, some residential lighting and "lights that are left on when the light is not needed."

If council adopts Pincott's proposal, there are plenty of bylaw models to choose among, including ones that simply require such things as shields to be placed on street lights to keep the light focused downward, others that set wattage restrictions and decree when outdoor lights can be lit, and still others requiring that lights in office towers be turned off.

Any bylaw should place the emphasis on educational campaigns and incentives for businesses. Voluntary compliance is more desirable and more productive than iron-fisted enforcement.
