Remote Control LED Light Bulb Offers 7 Shades of White
by Steve Levenstein
"Any color you like, as long as it's white!" No, it's not a bizarro version of Henry Ford, just Sharp's new LED light bulb. Using the included remote control one can dial through 7 different shades of white light - without any white heat.
Ambiance at your fingertips has arrived, thanks to Japan's Sharp Electronics Corporation. According to Sharp, the new DL-L60AV LED Lamp allows users to adjust the color function of the light bulb through a range of 7 different shades "ranging from a pleasing warm white to a cooler daylight white to match the weather, the season, time of day, purpose, or other preferences." The adjustment is done via a hand-held remote control that also allows users to tune the brightness of the bulb to suit their preference. Forget Henry Ford, what would Thomas Edison think? 
The thought of a single light bulb needing a remote control may seem somewhat extravagant but Sharp intends for the bulbs to act as stand-alone lamps; one per room is enough. The DL-L60AV LED Lamp is rated at 560 lumens - tops in the industry - yet cost a mere penny to run continuously for 11 hours. One especially "bright" feature of the DL-L60AV LED Lamp is its base; exactly the same as standard incandescent light bulbs so it can be used in existing lamps and light fixtures.
I'm not done yet: this bulb is cool - literally. LED's don't create heat like incandescent bulbs do, which means they don't waste energy on creating such heat.
They also differ from incandescent light sources in that they emit very little light in the 350-nm waveband, the part of the light spectrum that lies in the ultraviolet range and attract insects. This makes the DL-L60AV LED Lamp ideal for outdoor use, especially near entry/exit doors.
The DL-L60AV LED Lamp is one of nine new high-efficiency, mercury-free LED light bulbs to be introduced to the Japanese home market this July 15. All have the convenient screw-type base that negates the need for expensive retrofitting. Very cool indeed! (via Mainichi Daily News and Engadget)

Attractive LEDs = LESS need to ban light bulbs!
Very inventive!
Lot of new lighting ideas turning up these days, including higher efficient incandescents....
There are often comments of the type "wait for good LEDS so that light bulbs can be banned"
On the contrary, good LEDS still mean you DON'T have to ban ordinary light bulbs:
Given that LEDs are presumably going to be so good that people actually WANT to buy them - unlike 'energy saving' fluorescents, CFLs - then
we are talking about a similar situation to transistors and radio tubes - the latter weren't banned just cause the others turned up.
People can of course make up their own minds anyway whether or not energy cost is worth it in relation to light bulbs and the advantages they - like all lights - have, and they might be in rooms/lamps that are not used that often anyway, so that energy savings hardly come into it, compared to upfront light bulb cost.
As for emissions, does your bulb give out any gases?
Even your power station might not give out CO2 emissions - which unfairly denies emission-free energy consumers what they want to use (ordinary light bulbs bought 19/20 times USA, 9/10 times EU).
For others linked to say coal power stations, the power station emissions themselves can of course be dealt with, directly or by energy substitution
