Earth-friendly lighting … LEDs #2 tio

Yet more proof that LEDs are the future for lighting in the home … this time coming from curtisory of those happyt guys over at The tip we’re interested in says:

2. Get the LEDs out: LEDs, or light-emitting diodes, are extremely energy-efficient and long-lasting light bulbs. They cost more than CFLs, but use less energy and last longer. An LED light bulb can reduce energy consumption by 80 to 90 percent and last around 100,000 hours.

BBC RADIO 4, Science, The Material World

Yet another step forward in LED technology is being made. The new generation of LED bulbs will not only light our homes and offices but could also be used to keep data safe and purify water!

These advances were discussed in an interview with Dr Rachel Oliver during the BBC Radio 4 programme The Material World (6th Dec 2007). Dr Oliver is an LED researcher from the University of Cambridge.

LEDs have enormous benefits over standard light bulbs because they’re a great deal more efficient, come in a range of different colours and have a very long lifetime. They are also good at saving energy too.

Because they last such a long time, architects could cover the side of a building with exciting lighting effects without worrying about constantly replacing the bulbs.

The interview continued to go into depth with a discussion on the colour properties of current and future LEDs.

We’re aiming for white light that looks like sunshine, and there are scientists trying to mix phosphors in just the right proportions. If we can achieve this, the white will not only look warmer, but could also be useful for people with Seasonal Affective Disorder (SAD).

At UltraLEDs we have many years of experience of working with LEDs and are constently searching the globe for the best LED products. You can view out latest products via this link

Go GREEN - More or Improve

If you go into the News Agents remember have a look at the latest MOVE OR IMPROVE magazine.  With WINTER upon us it’s a great time to think about your lighting requirements. Switching to LED technology can SAVE MONEY and help to SAVE THE ENVIRONMENT at the same time.

From recent experience it can also be a great safety device.  I recently helped a friend change over to LED bulbs in their Kitchen. While removing one particular bulb it became evident that the bulb had been touching some fabric. Upon close inspection it was obvious that the fabric had nearly caught fire. While this is an extreme example … it clearly illustrates the benefits of LEDs which radiate little heat vs. TRADITIONAL BULBS  which radiate as much as 90% to 95% of their energy as heat.
