    It's a busy week for Vizio. The budget TV manufacturer flaunted its flashy new tablet in front of our cameras yesterday, and had us hopping across town this afternoon for a chance to go hands-on with its latest entrant into a mysterious brand-new product category (for Vizio, at least). Reps were mum on details, so we had no choice but to return to the CEA LineShows in NYC to see what was up. We walked around the booth, looking for signs of that Vizio Android phone we saw at CES, only to find co-founder Ken Lowe cradling the new goods: a line of light bulbs. We laughed. Then asked to see the real product that Vizio insisted would be worth the trip. Nope, that was it: a LED light bulb -- four of them, in fact, arranged in height-order on a chrome bathroom vanity fixture. Lowe then proceeded to introduce his product as he has any other, so we hit record. They're bright, round, and standards-compliant, and will be coming to a screw-in fixture near you in Q3. How much? "A Vizio price."%Gallery-126935%

    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.

    We know what you're thinking, but the Jolly Green Giant didn't drop something on the way to hang out his laundry. Designed by Steffi Min for her industrial design senior thesis, the Peg lamp looks and functions like an oversized clothespin, directly clipping onto a standard light bulb. As you can see in the video after the break, changing a bulb takes only a second or two, and there's almost no risk of broken glass. We don't expect a clothes pin connector to appear as a retail product anytime soon, but if we can build our own humanoid robots, we can probably find a way to slide an oversized rubber band around two wedges of wood.

    While Democrats and Republicans squabble over the future of the incandescent light bulb, a Livermore-based company has produced an LED that they claim could lead to brighter, more affordable solid state lighting. By growing gallium nitride on low-cost silicon wafers, as opposed to the typical sapphire and silicon carbide substrates, the company has achieved an output of 135lm/W (lumens per watt) with a color correlated temperature of 4730K-- brighter than any affordable LED lighting solution we've ever seen. Of course, this isn't the first time efficacy of this level has been achieved, and we've yet to see a practical application, but if Bridgelux's numbers are right, this could mean a 75 percent cut in LED production costs. The company expects the technology to make its way to real world lights in the next two to three years -- perhaps by then the furor over pigtail light bulbs will have settled a bit. Enlightening PR after the break.

  • Cree shows off 'no-compromise' LED replacement for 60-watt incandescent bulbs

    Compact fluorescent (or CFL) bulbs may currently be the dominant alternative to traditional incandescent light bulbs, but there's still a strong contingent betting on LEDs as the true long term replacement. One of the major players in that camp is Cree, which recently teamed up with TESS and Dean Kamen's FIRST organization to have kids distribute LED light bulbs like Girl Scout cookies (seriously), and is now showing off what is says is the "first no-compromise replacement for a 60-watt incandescent bulb." That bulb is dimmable, and emits a "beautiful, warm, incandescent-like color of 2700 K," while delivering more than 800 lumens and consuming less than 10 watts (meeting the Energy Star requirements for a 60-watt standard LED replacement bulb). Unfortunately, there's one big catch -- the bulb is still just a prototype, and Cree says it hasn't yet decided how it will bring it to market, or how much it might cost. Head on past the break for a quick video demonstration.

    No one's going to be calling Nokero out for falling behind. Just a few short months after revealing its first commercial light bulb for developing nations, the outfit has now rolled out a second version, the predictably titled N200. This guy strikes a vastly different pose compared to the original, with the LED enclosure hanging on a swivel that enables it to be positioned in a way that would optimally catch light. When night falls, users can flip the light north to create a lantern. Nokero claims that this edition is just as rugged and rainproof as the original, but it's 60 percent brighter and lasts three times as long. A single NiMH battery is included, and that's what is rejuvenated by the sun -- once charged, it'll provide between 2.5 and 6 hours of light, depending on the mode. It's on sale now for $20 apiece (bulk prices are less), representing a modest $5 premium over the (still available) N100. Can't say the Yankees will be looking to decorate their outdoor patio with lighting right about now, but for the nomads trekking to Panama to escape Old Man Winter... well, you know what to do.

    Segway inventor Dean Kamen just stole the show at TEDMED 2010, with both a far-reaching lecture on how technology can save the developing world, and a peek at his latest projects. We'll spare you the wave of guilt for now and get right to the cool stuff, like the latest rendition of his Luke prosthetic arm and Slingshot water machine. Dean admitted he's having difficulty finding companies interested in manufacturing the former, but it's looking snazzier than when it last grabbed Stephen Colbert, with components like this shoulder piece printed out of titanium in a custom 3D printer, and it's slated to look like this. The Slingshot's seeing even more action, as Dean and company have pulled it out of the ugly box into these svelte tubes, and finally has a distribution deal (with Coca-Cola, of all companies) to bring the clean-water-from-any-source machines to developing countries in trials early next year. Last but not least, the man's got a product you might be able to afford for your home. In the quest for an item for his FIRST young engineers to sell -- a la Girl Scout cookies -- he tapped LED manufacturer Cree to produce an 450 lumen light bulb that draws just 7 watts and will retail for about $25 door-to-door. In case you're wondering, that's cheaper and more efficient than most any lamp we've seen before. Dean says they've already produced several hundred thousand of the bulbs thanks to a surprise $3 million investment from Google, and plan to have them in the hands of every FIRST kid soon. Keep on fighting the good fight, Dean. %Gallery-106215%

  • GE introduces 'hybrid' bulb with both halogen and CFL elements, instant-on meets efficiency

    We're pretty okay with waiting the second or so it takes a typical CFL to light up, but sometimes, when we're checking for monsters in closets and other inconspicuous places, it'd be nice if things were a little more expedient. For those times (and for generally impatient people) GE is introducing its Hybrid Halogen-CFL bulb. It's basically a typical CFL unit, but look closely inside those coils and you'll spot a wee halogen bulb peeking out. It's like two bulbs in one, the halogen unit powering on almost instantaneously then fading off once the CFL element gets itself all riled up. We're wondering how well the output from the two elements match, whether you'd be able to notice the transition, but we're even more curious about the cost. GE says we'll have to wait a few months to learn that bit of info, and the same holds true if you're looking for a release date more specific than "2011." Hopefully it isn't too late in the year, as LED bulbs are getting cheaper by the minute.

    There may still be plenty of competition among potential successors to the incandescent light bulb, but there's little question that the traditional light bulb is on the way out -- a fact now further backed up by GE's closing of the last major factory making the bulbs in the US. GE had apparently considered a $40 million investment to retrofit the plant -- located in Winchester, Virginia, and employing some 200 workers -- to manufacture compact fluorescent light bulbs, but it says that bulbs made at the plant would have cost 50 percent more than ones from China, which is where the vast majority of CFLs are made. Of course, that shift hardly happened overnight -- be sure to hit up the Washington Post article linked below for a brief history of what led to this point, and a closer look at the plant itself.

    We never really had a problem with traditional CFL design, but it's always nice to have options when you're looking for new ways to decorate. London-based outfit Plumen has bent the usual coil shape into a more abstract pattern that we're sure will fit perfectly in our quirkily stark / offbeat loft uptown. The Plumen 001 model shown here ships on October 5th in the UK for £20, or €30 in the rest of Europe, but mum's the word on a North American release. From the looks of their Flickr, there are even crazier shapes in the works, though. Hypnotic spinning bulb footage after the break.

    Incandescent light bulbs are definitely not in fashion these days (the last time we stepped inside Ikea we were greeted with their announcement that the company plans to stop selling them) because of their total lack of efficiency. Don't tell that to this concept for a tea kettle, however, which uses the wasted energy of the bulb (nearly 98 percent) to make water for your tea. Now, it doesn't actually bring it to a boil -- just to 194 degrees Fahrenheit -- but many tea enthusiasts will tell you that your water should be just off the boil anyhow. So there.

  • How nutritious is your light bulb? (in lumens, of course)

    No joke -- starting mid-2011, US light bulbs will have nutrition facts of their own. Backed by Congress, the FTC has mandated that light bulbs carry the label at top, allowing buyers to clearly compare brightness, life expectancy and energy cost. Of course, many manufacturers call out these facts already, but hopefully this will keep the rest from confusing potency with power -- by advertising that a mid-range LED unit that slowly sips energy, for instance, is "equivalent to 40 watts."

  • Lite-On's Mobile Lamp LED bulb works even when the power is out

    We hate to break it to you, but those LED light bulbs that are shaped like traditional light bulbs? It's all a lie. LEDs are naturally pretty small things, and while there might be dozens scattered about inside a bulb there's still plenty of empty space in there meant only to make the things about the same size as a good ol' incandescent. Lite-On, however, has found something to make use of that space: batteries. The company's Mobile Lamp bulb can stay on for up to two hours even after the power is turned off, effectively turning it into a flashlight. To switch the bulb on or off you simply touch the copper part while something conductive makes contact with the metal part on the bottom, which could be a lamp socket or just a finger, as shown in the brief video after the break. The bulbs are due to be out sometime next year and should be hugely popular in areas with unreliable power -- or with an abnormally high rate of magicians per-capita.

    Oh, sure -- the world has plenty of those ritzy LED light bulbs to choose from, but how's about using the ultimate light source to create... even more light! That's exactly what Nokero is setting out to accomplish with its N100, which is being christened the "world's first" solar light bulb. Designed specifically for use in developing nations where continual electricity is a mere pipe dream, this bulb is housed in an ultra-rugged, rainproof enclosure that can provide around four hours of light when fully charged; if you leave it in the sun all day, it'll harness enough juice to provide illumination for around two hours. The unit itself is constructed from impact resistant plastic and includes a foursome of solar panels, five LEDs and a replaceable, nickel metal hydride battery that's said to last two years. The company informed us that these will run you around $15 if purchased one at a time, though the goal is to sell 'em in bulk for around $6 apiece and have them delivered to rural parts of India, Africa and possibly District 9. Go on and get schooled by heading past the break and clicking play. %Gallery-94767%

    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.

  • The Home Depot takes LED lighting mainstream with $20 bulbs

    Slowly but surely, LED light bulbs have been getting brighter and more efficient, but price has always been a major factor staying their adoption. Back in 2007, a single 308 lumen bulb cost $65, and the more things changed, the more they've stayed the same. Now, out of the blue, The Home Depot has stepped forward with a cost-effective alternative. For $20, the new EcoSmart LED bulb promises a 429 lumen, 40W equivalent with a 50,000 hour expected lifetime, making it cheaper and nearly as powerful as the 450 lumen, $40-50 design industry heavyweight GE unveiled last month. Best of all, it's already available for purchase (though backordered) at our source link. Honestly, we're starting to wonder what the catch is. PR after the break.

  • GE's LED light bulbs look cool, last forever, cost a lot

    Citizens of the Earth, you're looking at the lightbulb of the future. In the coming years and decades our lives won't be illuminated by simple spheres or coils of white. Oh no; future bulbs will have cool fins and flares that make them look almost worth the $40 to $50 we'll pay for the things. That's what GE plans to ask for its Energy Smart LED bulb when it ships sometime in the next 12 months, and while that is a lot compared to the exiting options, look at the benefits: GE's bulbs will last a whopping 17 years when used four hours a day, and they give off light in all directions -- not focused in one spot like previous designs. But, most importantly, they're very efficient, using nine watts to give off the equivalent amount of light of a 40 watt incandescent bulb. That's 10 percent less than a 40 watt equivalent CFL, and there's no mercury or other toxic goop involved here either. It's the future, folks. Start saving. %Gallery-90389%

  • Nanofiber lighting promises to be better, safer than incandescent or CFL bulbs

    Well, it looks like you can add another contender to the great light bulb debate -- a group of researchers from RTI International now says that nanofiber lighter is more efficient than incandescent light bulbs, and safer than compact fluorescents. The secret to that, it seems, is a combination of nanofiber-based reflectors and photoluminescent nanofibers (or PLN), which together are able to form a lighting device that pumps out more than 55 lumens of light output per electrical watt consumed. That's five times more efficient than a regular incandescent light bulb, and since there's no mercury, the researchers say it's far safer than CFL bulbs. What's more, it's also apparently able to produce more natural light than CFLs, although there's noticeably no mention of potential pricing -- they do say that the first products using nanofiber lighting could be available in three to five years, though. Video after the break. [Thanks, DeFlanko]

  • Vu1 Corporation sees bright future for ESL light bulbs

    Rivalries. Controversy. Government intervention. The life of a light bulb isn't easy these days, and it looks like things are about to get even more complicated. While CFLs and LEDs may now be fighting it out to replace traditional incandescent light bulbs, Seattle-based Vu1 Corporation says it has developed a new type of bulb that's better than either of 'em, and could hit the market by mid-2010. Making use of ESL technology (or electron stimulated luminescence), the new bulbs seem to be the cure-all many folks have been looking for, with them promising to provide a more natural light than CFLs or LEDs, turn on as quickly as an incandescent bulb, and eliminate some of the pesky problems associated with CFLs (like their use of mercury). According to the company, they'll also be about as efficient as CFLs, although they will cost about $20 a pop to begin with, which Vu1 says is comparable to a dimmable CFL reflector bulb. Some bold claims to be sure -- claims made even bolder by the must-see "documentary" after the break.
