The best smart LED light bulbs
By Grant Clauser This post was done in partnership with Wirecutter. When readers choose to buy Wirecutter's independently chosen editorial picks, it may earn affiliate commissions that support its work. Read the full article here. We considered more than 20 smart-light-bulb systems and then spent eight weeks testing 10 contenders, confounding a family of four by constantly changing how their lights worked. After all that, we determined that the Philips Hue White and Color Ambiance A19 is the best all-around smart LED bulb. Hue lets you change your lighting color easily and does everything other smart light bulbs do, and it's also part of a larger product and app ecosystem, allowing for more flexibility and creativity than any other smart bulb we tested. Plus, it's compatible with the widest variety of smart-home systems, including Apple's HomeKit, Samsung's SmartThings hub, Amazon's Alexa, and Google Home. It's not the cheapest bulb we tested, but its reliable performance and wide compatibility make it a solid choice for any smart-home enthusiast or newbie.
Fitbit introduces Flex wristband at CES 2013
Fitbit is one of the oldest names in fitness tracking these days, though given how new the industry actually is, the company's not really that old at all. But they have been around for a few years now, and this year at CES, the company introduced one more addition to its line of motion-based trackers. The Fitbit Flex is a wristband-style tracker (similar to the popular Nike FuelBand) that's designed to sit up near the higher end of the Fitbit line. At US$99.95, it's not very cheap, but Fitbit obviously wants this to be one of their most popular of trackers, making it easy to strap to your wrist, and from there track all sorts of stats, including steps taken, calories burned, time active, and even sleep time and quality. The Flex comes in five different colors, and each one has five different LED lights that are designed to let you know how close you are to your goal for the day, whatever that is. The device looks very smooth, and while the $99.95 price might be a tougher sell for those not yet on board the fitness tracker train, it definitely gives Fitbit one more excellent option in a market that's quickly filling up. Our good friends over at Engadget have more on the device, including a full gallery and a video with hands-on footage. The Flex is coming later on this spring, though you can pre-order it from Fitbit starting right now.
Ikea to sell only LED-based lighting by 2016, wants to be greener than your sofa bed
While some wouldn't necessarily associate Ikea with eco-friendliness given that its business revolves around plywood, the furniture chain has just staked out a clearer position as a green pioneer. It's phasing out sales of all lighting that isn't LED-based by 2016, making it the first major home furnishing shop with a US presence to entirely banish less efficient illumination. Ikea also wants to take advantage of its economies of scale with the "lowest price on the market" for LEDs, which could shake up an industry where anything beyond incandescent technology usually carries a premium. We'll still have some time to wait for the full switch, but the company at least plans to practice what it preaches by replacing over a million store lights with LEDs -- so those of us with no light replacement plans can still feel as green as the Beddinge Håvet we're taking home.

Eyes-on with Energizer's LED lighting solutions and USB chargers at CES 2012
Energizer doesn't get much coverage here at Engadget, primarily because those AA cells you see at the Walgreens checkout counter haven't changed much throughout the years. Every now and then, however, there are special events such as CES, where the company that keeps going and going trots out its latest products for techies to fawn over. This year, we got to check out its lineup of USB power solutions designed for the home and automobile, along with a very handsome set of LED lights. Next month, Energizer will release new 5W chargers that include either a USB cable or Apple's dock connector. These are available for both the home and car, and will retail for $24.99 each. Perhaps most intriguing, however, is a product that combines both a wall and car charger into one handy unit. Known as the 2-in-1 USB Charger, it will retail for $39.99 and is set to hit store shelves this summer. In every situation, a cord management system is built into the unit, which is simple, effective and thoughtful. Then we have its beautiful accent lighting solution that makes up the Edge Collection. Available in small and medium sizes, they were introduced in September of this year and feature rather dramatic dimming options that respond to touch at the base of the unit. A single press will turn the light on or off, while a continual press causes the lamps to slowly dim or brighten in a slow and smooth gradation for a perfect lighting level. They do get quite bright, too, as the small light ($64.99) puts out up to 350 lumens, while its larger brother ($79.99) pushes it all the way to 400 lumens. With no physical switches and bulbs that don't need to be replaced, Energizer's Edge Collection seems to be a long-lasting product that can either add a curious focal point or elegantly blend into the background of any room.
Mutewatch wrists-on: stay on-task with good vibrations (video)
No, the picture above isn't some modernized Power Ranger's wrist communicator. This is the Mutewatch, and we've been intrigued since we first laid eyes on it over a year ago. At a glance, it looks akin to a rubber fashion bracelet, which could make its $260 price tag a shocker. But with the right touch or flick it reveals itself to be much more. The Stockholm-based start-up behind it, dubbed Mutewatch AB, envisions the device serving as "time management tool" for setting quick wrist-felt vibrating reminders during the course of the day. Think Growl, but on your wrist. The wristwatch lacks a dial and crystal, and instead has an angled, touch-sensitive section for a face with hidden LEDs, an ambient light sensor, a motion sensor and a vibrating motor for alarms. We've spent some time using a near-final unit seeing what it would be like silently manage our days, and it's all laid out just past the break. %Gallery-134989%
Batarang controllers to be thrown at E3, come back in October
If multiple batmobiles, a bat-usb stick, and a bat-puter aren't enough to convince you Bruce Wayne is a vain egomaniac, maybe these Batman: Arkham City batarang controllers will give you pause. In traditional bat-gadget fashion, these Xbox 360 and Ps3 controllers boast a cheesy bat-aesthetic (such as bat-start and select / back buttons), dual rumble motors, comfort-soft grips, and seven switchable splashes of LED color. Although physically the two controllers are pretty similar, Ol' Bats seems to favor the PlayStation 3, giving its controller not only the popular Xbox 360 button / analog layout, but an internal battery, detachable charging cable, and batman-themed USB RF receiver, to boot. The Xbox variant? A dated, wired affair -- but hey, at least it's got that Xbox guide button, right? The controllers will be on display next week at E3, courtesy of Power-A, and will hit store shelves when Batman: Arkham City ships in October, leaving you little excuse not to be geared up and ready when the bat-phone rings. Hit the break for the official press release... or, you know, have Robin do it for you.
Mutewatch now in production, set to silently manage your day by July (video)
We first caught wind of Mutewatch AB's eponymous sort of anti-watch -- a personal vibrating time management wristband, equipped with a hidden touch-activated LED display -- when it became available for pre-order back in August. It seemed unique, but back then we had no idea of how it looked in action or when we might finally get one strapped onto our wrists. It's a mystery no more, as the Swedish suite has just released a heavily stylized (and totally rendered) video showcasing the Mutewatch's various touch-enabled functions. Also in tow, a press release announcing retail availability in July. Although our cellphones can do pretty much the same thing as this spendy $259 timepiece, we can't hide our geeky (and guilty) lust for one. You can check out the video for yourself past the break, but be warned: a moderate case of GAS -- Gadget Acquisition Syndrome -- may occur after viewing.
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.
Flexible, implantable LEDs look set to start a new body modification craze
LED lights are cool, you're cool, why not combine the two, right? We doubt that's quite the reasoning that led to this international research project, but it's certainly an appealing way to look at it. Our old buddy John Rogers from the University of Illinois at Urbana-Champaign has headed up a research team with participants from the US, China, Korea, and Singapore, who have together produced and demonstrated a new flexible and implantable LED array. Bettering previous efforts at inserting lights under the human skin, this approach allows for stretching and twisting by as much as 75 percent, while the whole substrate is encased in thin silicon rubber making it waterproof. Basically, it's a green light to subdermal illumination, which could aid such things as monitoring the healing of wounds, activating light-sensitive drug delivery, spectroscopy, and even robotics. By which we're guessing they mean our robot overlords will be able to color-code us more easily. Yeah, that must be it.
Cyglo Night Bright Tyres turn on the magic of colored light
Just in time for that Tron reboot comes a set of tires for your ride that will not only see you looking fresh at night but could also keep you from becoming someone's hood ornament. They're called Cyglo Night Bright Tyres, featuring embedded LEDs in the tread and the sidewalls. At a standstill the lights are well-separated, but get moving and they stream together to form a lighted arc powered by the motion of the wheel itself -- no batteries to change or charge. The folks at Cyglo have had the idea for quite some time now but have newly received patents to protect the idea in the US and UK, meaning they're finally close to production. The cost? Unknown, but surely not cheap. Another pic awaits you below, plus a glimpse into the company's inspiration.
Graduation cap modded with LED array, steals show (video)
Yomo Gaocho, an enterprising young man about to graduate from Northwestern University, has put together pretty much the coolest grad cap mod we've seen. Not that we're experts on the subject or anything, but the array of 256 LED lights adorning his cap surely makes for one of the geekiest ways to bid adieu to one's undergraduate studies. He's taking it one step further too, by programming animation patterns into the white LED arrangement and offering advertising space -- we're not kidding -- for any unorthodox companies that may wish to have him as a walking billboard. See Yomo's creation on video after the break, or hit the source for a guide on how to make your own light-fantastic grad cap.
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.
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.
Nanosys and LG Innotek agree deal for newfangled LED-backlit displays
For the nitty gritty of how Nanosys' proprietary LED backlighting technology works, check out our earlier coverage here -- what you really need to know is that the company promises a significantly wider color gamut from its displays, while reducing power consumption by up to 50 percent. Quantum dot LEDs have shown their faces before, but now there's the big hulking heft of LG Innotek -- LG's component manufacturing arm -- behind what Nanosys is offering, which indicates we might actually see the release of nanotech-infused displays within the first half of this year as promised. The early focus appears to be on mobile phones, which gives us yet another next-gen feature to add to our list of requirements for our next phone. Check out the full PR after the break.
Nanosys offers better saturation of LED-backlit displays with nanoscale coating
While we all wait around for larger-sized OLED displays to become feasible for the consumer market, Nanosys has stolen in and demonstrated a new LED coating technique that proposes to radically improve color saturation in LED-backlit screens. Based on standard blue LEDs -- the most efficient kind -- this works by applying nanoparticles to the light and thereby endowing it with the desired hue. While the nano-coating can make standalone LED lights far richer in color, the real potential is in its deployment in LED-backlit displays, such as those becoming dominant on laptops today. By employing a coated array of blue LEDs instead of the standard white stuff, this can deliver greater color saturation while fitting within the same energy profile of current LED tech. Products boasting Nanosys' new hotness are said to be coming out later this year, with some appropriate premium slapped on the price for the fancier output.
Skull belt buckle / LED "display" / MP3 player wants to fight your battles for you
So, we're not going to say this is the greatest thing we've ever seen, because we've seen some pretty awesome things in our years and years of living on the edge, but it's pretty, uh... heavy metal. Regardless, the so-called "Punk Skull" belt buckle is one multi-talented reminder of Death: he holds up your pants, but can also play MP3s (1GB player included) or display fascinatingly terrifying LED light patterns (LED module included) -- though sadly, not both at once. If that's not enough uses for you, the manufacturer suggests that the buckle is solid enough for you to use "as a handheld weapon," which is great, because we suspect that suddenly, a lot of people are going to start wanting to fight you. Available now for wholesale, we're pretty sure they'll be making their way to high-end retailers near you soon, and that they'll be horrifically affordable. A few more shots of the carnage after the break. [Via Random Good Stuff]
Rockefeller Center Christmas tree goes LED
It looks like the Rockefeller Center Christmas tree will be a considerably smaller energy hog this holiday season than it has been in years past, as New York City Mayor Michael Bloomberg announced yesterday that the tree will be lit up with LED lights for the first time - 30,000 of 'em, to be specific. That'll apparently reduce the tree's energy consumption from 3,510 kilowatt hours per day to just 1,297 -- a savings that, as the AP points out, is roughly equivalent to the amount of electricity consumed by a typical 2,000-square-foot house in a month. While it's not clear if it'll be used for the tree or not, the owners of Rockefeller Center also took the opportunity to show off a new 365-panel solar array on the roof of one of the complex's buildings, which is apparently big enough to lay claim to the title of the largest privately owned solar roof in Manhattan.[Photo courtesy of Wikimedia Commons]
PS3 pad loses DualShock name and vibration but picks up Wii-esque motion detection and wireless connectivity
In a shocking turn of events, the PS3 controller has gone from banamerang to wireless DualShock 3, except without the DualShock name and vibration.If you take a good look at the back of the new control pad (see the close-up above), you'll notice that the DualShock 2 brand name imprinted on the old controller has now been supplanted by a row of LED lights to show which input has been set, either wirelessly or via the wired USB recharge port. Sony's now the only name in-line for PS3 controllers either on the pad or in the press releases (see "the new PS3 controller").
