NEC announces LED light bulb production

nec-led-light-bulbMany companies that produce light bulbs are slowly changing their production lines due to new laws that ban ordinary, incandescent, light bulbs. There are many alternative technologies as white-light LEDs, oLEDs (we wrote about those in one of our previous articles), plasma light bulbs, CFL’s, etc. NEC Lighting Ltd announced their release of two types of LED light bulbs in September 2009, in Japan.

Their rated input power is 6W, and the illumination right below the bulb is equivalent to that of a 60W incandescent light bulb. There is no suggested retail price. But, because Toshiba Lighting & Technology Corp and Sharp Corp have already released LED light bulbs (with street prices still high comparing to incandescent, approx US$42.5), NEC Lighting expects the prices of their new products to be competitive.

This time, NEC Lighting reduced the power consumption by improving the power supply circuit and achieved power consumption about 90% lower than that of the company’s existing incandescent light bulb “LW100V54W.” The rated life is 40,000 hours, which is 40 times longer than life of a incandescent light bulb.

Unlike a bulb-shaped fluorescent lamp, the brightness of the new LED light bulbs reaches 100% at the moment of turning on the power. Their operating temperature ranges from 5 to 40°C.

NEC Lighting plans to stop producing and selling normal incandescent light bulbs and lighting equipment using them by 2012. Therefore, the company has been developing power-saving light bulbs to replace incandescent light bulbs. And it already released downlights that are as bright as 40W and 60W incandescent light bulbs and spotlights as the “LifeLED’s” series.

    This is simply false advertising. (1) The Rated Lumens are 350, but this is the peak, when the LEDs are brand new. What NEC is not telling us is the decay curve. LEDs decay very rapidly in the first few hours. The average L is more important, and will be surely much less. (2) 350 Lumens is no where near a 60W Edison bulb. At best, it is maybe close to a 30W bulb. Do you know how dim a 30W Edison is? (3) The number of LEDs inside the bulb is important. More than 1, and you get shadows. So, a task light that creates many shadows of the object illuminated is simply useless. BUYERS BEWARE!

    I use GU10 LEDs from a company called Homewatt and they’re great for bringing down your energy usage.
