The LED Revolution

| Monday April 18th, 2005 | 1 Comment

led.jpgBy now, you may have noticed that crosswalk signals have gotten a lot brighter, and a lot whiter. At the same time, traffic lights have have become pixelated and more clear. It’s all part of the LED revolution that’s sweeping cities and companies alike, saving energy and huge amounts of money in the process.
By replacing old traffic signals with LED powered signals, the NYC borough of Queens alone is saving over $600,000 a year, and other cities (and their taxpayers) are enjoying similar cost savings. Companies too, can enjoy the benefits by replacing traditional bulbs in places like hallway lighting, hotel reading lamps, and aircraft cabins. Enviropundit points us to more. There is also a discussion going on at Treehugger.

    Understanding the LED Revolution
    It is undisputed that high power LED is the future of lighting – things you need to know about the LED Revolution
    As world wide energy resources dwindle and power costs continue to increase the case for alternative, energy efficient lighting has never been stronger. High power LED lights consume at least two thirds less electricity than conventional light bulbs whilst offering the same brightness.
    Technology has advanced rapidly since the invention of the tiny ‘low power’ LED lights we see consuming power in ‘standby’ mode on televisions and other electronic devices. Low power LED light bulbs have been available for some time and whilst they are less expensive, they provide disappointing light brightness levels. The latest high power LED light sources use cutting edge technology developed in Silicon Valley, California making them much brighter and infinitely more efficient than their predecessors. High power LED now offers a real ‘like for like’ alternative to replace domestic and commercial light bulbs.
    High power LED light bulbs are more expensive than other types of light bulb but they are designed last for up to 50,000 hours, that’s more than ten years, so the initial cost is easily made up for.
    The cost of switching to LED can be spread by replacing old bulbs as they blow. Most conventional light bulbs only last about twelve months so the total cost is likely to be spread over at least a year. LED lights require zero maintenance and will not need to be replaced for a decade.
    LED lighting advances have been overshadowed by ‘curly’ compact fluorescent light bulbs as an alternative to the power hungry, soon to be outlawed, incandescent light bulb. Recent concerns over the safe disposal of CFL bulbs and international pressure to conserve the environment has resulted in government level promotion of LED as the future of lighting.
    Many ‘energy saving’ light bulbs are routinely criticised for providing poor brightness levels and light colour. The ‘flickering’ nature of some fluorescent lights has adverse effects in a work environment. High power LED provides a true ‘white’ light that is extremely close to natural daylight. High power LED lights are available in ‘cool white’ and ‘warm white’ colours.
    Unlike many light bulbs high power LED lights do not contain harmful chemicals, are safe to handle and can be recycled.
    High power LED light bulbs and fittings are available in an extensive range of formats which offer true substitutes for almost every conventional domestic, industrial and commercial lighting application.
    Saving energy by providing alternative, innovative light sources today will help to ensure a better world for tomorrow.
    We take our corporate responsibility to the environment very seriously. LED Revolution actively promotes awareness of innovative technologies that will help protect the planet by reducing our reliance on conventional fuels, save precious energy resources, halt the production of harmful emissions and contribute to keeping our planet safe.
    Proven energy saving LED technology already exists at a domestic level and is advancing rapidly, our aim is to increase public awareness of this easily implemented sustainable solution and introduce people to the basic principals of energy saving lighting techniques.
    Saving the planet will not be achieved by a single action or great idea. Millions of people working together with the same goals will. There are many ways that each one of us can contribute to protecting our environment and preserving precious energy reserves. One of them is switching to low energy LED lighting.
