"  This isn&amp;#039;t the LED lightbulb that&amp;#039;s going to put incandescents and halogens out of business, but the LED Party Bulb from Philips ($4.99 each, available later this month) is an unassuming harbinger. It fits in standard fixtures, is cool to the touch during operation and lasts for up to 50,000 hours. However, it doesn&amp;#039;t emit much light. And that light, unfortunately, is either blue, green, red or amber. LED makers are still plagued with difficulties inherent to generating that nice white (with a spritz of yellow) frequency that incandescent and halogen bulbs emit\u2014the closest any cost-effective LED can get is a harsh white with blue undertones. Philips has successfully used bluish-white LEDs in municipal lighting, such as in streetlamps, and in their new Aurelle Decklight (also available later this month, for $99.99). But for lighting the inside of a home, a bulb that gives you a corpse-like pallor isn&amp;#039;t likely to sell. The party bulb probably won&amp;#039;t sell either. The green bulb they sent us makes for a great nightlight or conversation piece for parties, since it never gets hot, is soft enough to use without a lampshade, and uses less than a watt of power. Still, it&amp;#039;s green. Another version of the bulb cycles through seven colors, making it sillier, but a better proof-of-concept for what wonders LED technology holds. We&amp;#039;re not being facetious\u2014LEDs are superior in nearly every way to the bulbs we use today, and employed en masse might be a crucial step towards mending our power-binging ways. And while no company comes close to Philips in this field, they aren&amp;#039;t alone; some of the greatest minds in the world are working towards that single, noble goal, of banishing the color blue.\u2014Erik Sofge Mood Lighting: Philips&amp;#039; new LED powered party bulb.
