Light Bulbs To Get Nutrition-Style Labels Next Year : TreeHugger - 0 views

  •  
    "Late last year we reported that the US Federal Trade Commission proposed a new label for compact fluorescent lightbulbs that would show vital statistics like mercury content and the light output in terms of lumens rather than watts, which would make the brightness of CFLs, LEDs and other lighting technology more comparable among consumers. Well word has just hit that the new system has been approved and we'll soon see nutrition-facts-style labels on our lights. EarthTechling gave us a heads up about the new label, pointing us to the announcement from the FTC. The FTC states, "Under direction from Congress to re-examine the current labels, the FTC is announcing a final rule that will require the new labels on light bulb packages. For the first time, the label on the front of the package will emphasize the bulbs' brightness as measured in lumens, rather than a measurement of watts. The new front-of-package labels also will include the estimated yearly energy cost for the particular type of bulb.""

Light pollution harms not just stargazers | csmonitor.com - 0 views

  •  
    But even on a clear night, many would-be astronomers are missing out on this rare celestial scowl, instead being treated to a dull haze punctuated by only the nearest or brightest objects, Jupiter not being one of them. So pervasive is this murky veil that the National Park Service estimates that two-thirds of Americans cannot see the Milky Way from their homes. Had Carl Sagan spent his whole life in a contemporary US city, he'd no doubt have marveled at the dozens and dozens of lights dotting the firmament. The cause of this stellar pall? Carelessly designed streetlamp fixtures, signs, and office lighting controls that pointlessly illuminate the sky, blocking our view of the universe.

EU bans low-efficiency light bulbs from 2012: ENN -- Know Your Environment - 0 views

  •  
    EU governments have agreed a phase-out timetable to remove from the market all incandescent light bulbs and low-efficiency halogen bulbs by 2012 at the latest. The restrictions will be introduced as "implementing measures" under the energy-using products (EuP) directive and will begin to bite from next year. "It's a groundbreaking measure that will change the way we consume energy," EU energy commissioner Andris Piebalgs said after the decision was taken by a committee of member state representatives in Brussels on Monday. The move should be formally approved by the EU in early spring, following a three-month scrutiny period in the European parliament.

National Geographic Magazine - Light Pollution! - 0 views

  •  
    Light pollution in the broad sense refers to any nighttime artificial light that shines where it's not needed. This nocturnal brightness can disorient humans and a host of other animals, confounding eyes and biological rhythms that evolved in a world without such light. One way stray rays pollute is sky glow, the scattering of light by clouds and atmospheric particles that makes it difficult to see stars and other features of the night sky-an increasing problem. These maps show the global extent of sky glow. More than just snapshots of the Earth at night, they account for the light-scattering effects of clouds and dust, and show how bright the sky is above a given point on the ground-revealing that most of the world's population lives under night skies fuzzy with the haze of reflected light.
