Led-World Exclusive - LED Lamps with Remote Control

LED Lamps with Remote Control :
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 it has created a series of LED globes that includes a bulb with a remote-controlled, adjustable-color function and a dimmer.
The series of nine globes will be released in Japan in July. Model DL-L60 features an adjustable color function which allows users to change the light through a series of seven shades from warm white to daylight light. This model also includes a dimmer function, allowing the user to enjoy a range of color and brightness. Three other bulbs in the series are dimmer compatible, but the dimmer will need to be purchased separately.
The LED bulbs have a standard E26 screw base so will be compatible with all your existing lights and lamps. All models have a service life of approximately 40,000 hours and will not lose intensity or longevity even if continually turned on or off. With the exception of the DL-L60, users can choose bulbs with warm light or daylight white.
Warm white is described as being equal to the light from an incandescent lamp and daylight light is equivalent to bright daylight. Like other LED bulbs, they provide bright, even light and as they emit very little light in the ultraviolet range are less likely to attract insects and bugs. Prices are expected to range from ¥3880 (USD$40) to ¥7980 (USD$82).

LED Lighting Could Help Reduce CO2 Emissions 50 Percent Over 20 Years

LED Lighting Could Help Reduce CO2 Emissions 50 Percent Over 20 Years

Just by switching to LED lights, we could decrease carbon dioxide emissions from electric power use by up to 50 percent in just over 20 years. A recent report by McKinsey & Company states that making this switch is possibly the most cost-effective way to tackle global warming using existing technology.

LEDs are more than twice as efficient as compact fluorescent bulbs, currently the standard for greener lighting. Unlike compact fluorescents, LEDs turn on quickly and are compatible with dimmer switches. And while fluorescent bulbs contain mercury, which requires special disposal, LED bulbs contain no toxic elements, and last so long that disposal is not much of an issue.
“It is fit-and-forget-lighting that is essentially there for as long as you live,” said Colin Humphreys, a researcher at Cambridge University who works on gallium nitride LED lights, which now adorn structures in Britain.
The switch to LEDs is proceeding far more rapidly than experts had predicted just two years ago. President Obama’s stimulus package, which offers money for “green” infrastructure investment, will accelerate that pace, experts say. San Jose, Calif., plans to use $2 million in energy-efficiency grants to install 1,500 LED streetlights.
LEDs have a high initial cost, no doubt – an outdoor spotlight can cost up to $100, compared to $7 for an incandescent bulb. But, imagine not having to change that light bulb again for 20 years or more, and paying pennies on the dollar for power consumption compared to ‘regular’ light bulbs.
They’re still not perfect, being better suited for directional lighting than general lighting needs, but scientists are already finding new ways to address these problems. It’s a start!
