I have mixed feeling about energy efficient bulbs. They aren’t easily disposed of and contain mercury – isn’t it dangerous? What are the advantages of using them? A: Energy saving light bulbs should not be put in your household waste. Because they belong to the ‘electrical waste and electronic equipment’ category, sellers are obliged to provide information on how they can be recycled. The amount of mercury that energy efficient bulbs contain is as small as the head of a pin. They use about 80% less electricity than standard bulbs. Fossil fuels, such as coal, are the biggest sources of…

Quantum dots are tiny semiconductors with a variety of technological applications within the fields of medicine, biology, computers, solar panel technology and lighting. When filtered though quantum dots, light from LEDs (light-emitting diodes) becomes softer and more incandescent, which is generally considered more pleasing to the eye. A panel of QDs solves the ‘color quality’ issue associated with LEDs, which are far more efficient than incandescent bulbs and compact fluorescent lamps (CFLs); and do not have the toxicity issues of CFLs, which contain mercury. Aesthetic objections to both CFLs and LEDs are that they give off an ‘unnatural’ light. This…

The race to provide cutting technology that is also climate friendly is producing some cool new products with ever dwindling carbon footprints. That is the idea, anyway. Organic light-emitting diodes, or OLEDs, are similar to normal LEDs, but with an organic layer providing the illumination – and they are set to revolutionize how we light our houses. An article in the London Times describes how light-emitting wallpaper – and even paint – could replace the familiar bulb, providing indoor environments with ‘an even glow, which mimics sunlight and avoids the shadows and glare of conventional bulbs.’ And all for far…

Designs made from tens of thousands of light bulbs brighten up the holiday season in downtown Hong Kong – at an enormous cost of energy. But now many festive light decorations in the Chinese city are using energy efficient LED lights instead of standard bulbs. LEDs use around 80% less electricity than normal lights and last around 20 times longer, according to a CNN video report. The LED displays are dazzling and multipurpose – each bulb can create 16 million different colors and will be used for Chinese New Year as well as Christmas decorations. New York and London are…
