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.  Read More

Toshiba LED light bulbs at CES 2010

Toshiba, was waving the green flag at CES this week in announcing that its E-CORE LED lightbulbs will soon be available in the US market. An E-CORE bulb has a life expectancy of 40,000 hours, which is 40 times longer than traditional incandescant lightbulbs and at the same time it reduces CO2 emissions by 85 percent in comparison.  Read More

The Eternaleds HydraLux-4 liquid-cooled LED 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.  Read More

Sharp have developed a series of color changing light globes

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

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.  Read More

The 'holy grail' of lighting

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.  Read More
