Solar light bulb to brighten the lives of those in developing nations

As public consultation starts on ways to reduce and replace fuel-burning lighting around the globe, Nokero has announced a solar-powered LED solution aimed squarely at disaster areas and the developing world. The rugged, rainproof N100 is about the same size as a standard lightbulb but requires no electricity and offers users around two hours of bright light in exchange for a day's worth of sun. Read More

MusicLites WiFi-enabled LED bulb fuses light and sound

The outlook for piping music into office space or the shop floor is about to get a lot brighter. Lighting solutions company Osram Sylvania and audio innovator Artisan have teamed up to produce the MusicLites system - a 10W LED light bulb with a 70mm full range hi-fi audio speaker built in. The inclusion of a 2.4GHz wireless transceiver means that compatible audio devices can send music sound signals to the unit, which then pumps out both sound and light. Read More

GE sheds light on 40W replacement LED bulb

With many countries planning or having already implemented the phase out of incandescent bulbs, lighting company GE has unveiled a 40W equivalent Energy Smart LED bulb that consumes 9W, hence providing a 77 percent energy saving over its old-fashioned technological incandescent cousin. GE says the Energy Smart LED will produce nearly the same light output as a 40W bulb but will last 25 times longer. It is expected to be available to consumers later this year or early 2011.

Eternaleds' liquid-cooled LED light bulb

Liquid-cooled PCs are a mainstay for PC enthusiasts looking to eek every last bit of performance from their beloved machines and now it seems this approach has reached the world of the LED light bulb. A company called Eternaleds has introduced the HydraLux-4 LED Bulb, the world’s first LED light bulb to use "liquid-cooling technology" to give a true 360-degree light like a regular incandescent light bulb.

Incandescent light bulbs may have a bright future after all

In the face of legislation being enacted around the world, the future of the trusty incandescent light bulb has been looking dim. Ireland has banned the sale of incandescent bulbs, and the United States is set to phase them out by 2012. And it’s no wonder - the apple of Thomas Edison’s eye is something of an energy hog, especially when compared with modern bulbs such as compact fluorescent (CFL) bulbs and LED-based lights. But now a new technology from Deposition Sciences Inc of Santa Rosa, California, is promising a brighter future for the venerable incandescent. Read More

Sharp introduces color changing LED light bulbs

When it comes to choosing light globes these days, energy-conscious consumers have a multitude of choice. Both CFL bulbs and LED bulbs offer energy-efficient lighting and whilst they seem expensive at first, you realize they will save you money in the long term. However, a less appealing feature of LED globes is the bright, white light they emit, not particularly compatible with creating a warm, romantic feel in your home. That may be about to change. Sharp Corporation has just announced an LED globe that includes a remote-controlled, adjustable-color function and a dimmer. Read More

Smart Lite CFL replaces the bulbs not the ballast

Compact fluorescent lights (CFL) are a smaller version of their long established big brothers which, despite some drawbacks such as a small amount of mercury content, have gained serious ground in recent years as an energy-efficient alternative to conventional incandescent globes. CFLs reduce carbon emissions because they convert electricity into light more efficiently and also last up to ten times longer, but the globe still reaches its used by date long before the base (ballast) section that connects it to the power socket. 3E Technologies has identified this as another wasteful aspect of the process that could be eliminated and its solution is the Smart Lite - a two-piece CFL which allows the bulb to be removed from the ballast and replaced with a simple ‘insert and twist’ operation.

The GeoBulb LED light bulb

Not so long ago choosing a light bulb wasn’t too difficult. Just grab one with the desired wattage in either pearl or clear with the correct fitting for your socket. The need for energy efficient lighting means that it's no longer that simple, and given the amount of ongoing research in the area, the range of light bulb options on the supermarket shelves is set to explode. Technologies competing to replace conventional incandescent bulbs include OLED, Compact Fluorescent Light (CFL) bulbs, and of course LED bulbs. LED bulbs offer improved energy efficiency, produce brilliant light and offer long life and this new LED bulb offering, called the GeoBulb II, puts out more light than a standard 60-watt bulb and uses just 7.5 watts.

US$3 LED light bulb lasts 60 years, could end battle of the bulbs

Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost just GBP2 (USD2.80) and last up to 60 years. The gallium nitride based bulbs are 12 times more efficient than conventional tungsten incandescent bulbs and three times more efficient than compact fluorescent low-energy bulbs. As well as lasting 100,000 hours, ten times as long as today's eco-bulbs, the LED bulbs do not contain mercury, so disposal is less damaging to the environment, they do not flicker and fully illuminate instantly, unlike the current generation of eco-bulbs.
