Philips EnduraLED A21 bulb offers bright light for big bucks
If the expected price tag for Philips' latest LED light bulb is any indication, a brighter tomorrow won't come cheap. The "75W replacement," known as the EnudraLED A21, apparently reduces energy by 80 percent, lasts 25 times longer than its conventional counterpart, and is expected to cost between $40 and $45. Given that's significantly less expensive than the outfit's 60W equivalent, but for us regular folks, that's not exactly a drop in the bucket. However, if you're picking up what Philips is laying down, the bulb -- which uses a mere 17 watts of electricity to beam 1,100 lumens -- could save the US 5,220 megawatts of electricity and $630,000,000 annually (if we all switch over tomorrow). That certainly sounds good, but somehow we doubt a $45 light bulb is going to be the incandescent killer. Full PR after the break.
Inhabitat's Week in Green: LED lights, biofuel airplanes, and prescription tattoos
The Week in Green is a new item from our friends at Inhabitat, recapping the week's most interesting green developments and clean tech news for us. This week Inhabitat saw the light as we showcased an array of exciting developments in energy-efficient illumination. First off, Philips dazzled attendees at this year's Lightfair expo as they unveiled the EnduraLED -- the world's first LED replacement for those ubiquitous energy-sucking 60 watt incandescent bulbs. We were also excited to see the unveiling of the SolPix - a giant energy generating LED wall that doubles as solar shade and can be installed as high-tech building cladding. And if you think energy-efficient lighting isn't easy on the eyes, check out this beautiful LED flower that soaks up sun during the day and blooms at night. We also looked at several incredible (and insane) futuristic modes of transportation - for starters, how about an electric zip-line backpack that shoots you through city streets? We were also impressed by the Cell, a shape-shifting electric vehicle concept that comes complete with its own car-sharing transit system. And if soaring through the skies is more your style, check out these self-sufficient airships that harness solar energy to generate biofuel. Wearable tech saw several developments as well - this week we looked at the ultra-efficient 3d printers that created Iron Man's suit of armor. In other news, your next trip to the doctor could merit more than a single shot in the arm - researchers are developing a new type of "prescription" tattoo that keeps tabs on glucose levels using infra-red ink. Finally, we saw several remarkable inventions that stand to change how we combat climate change and construct our built environment. This week Bill Gates unveiled plans to invest in the development of a fleet of seawater-spraying mist machines that could combat climate change by creating sunlight-reflecting clouds, and we looked at a new type of biologically crafted brick that can be "grown" from a combination of sand, bacteria, and urine.
Philips' new LED light bulbs are brighter, more efficient, not cheap
Philips' Master LED bulbs may well have been forgotten in the US -- as far as we can tell, they never showed up for that hot date last July -- but it's hard to be miffed when the company's new bulbs, dubbed EnduraLED, are four times as bright. Due in the fourth quarter of the year, the 60W equivalent at left sucks down only 12 watts of electricity but emits a reported 806 lumens of soft white light -- a ratio green enough to save the world, Philips claims, if only you'll buy in. Problem is, people's generosity typically depends on price, and a company rep told us we'll shell out around $60 per bulb when the shiny silver socketables ship. Mind you, that's just an initial figure, but until we hear different we'll be going to Home Depot for our lighting needs, thank you very much. Press release after the break.
