The first Made-for-Google lightbulbs don't require a hub
To date, using Google Assistant to control your lighting away from your phone has typically meant shopping for both a smart speaker and bulbs with a hub serving as a go-between, such as Philips' Hue line. You won't have to spend quite so much cash going forward, because GE has unveiled the first Made-for-Google lightbulbs, and they don't require a hub at all. It's updating its C by GE lineup to automatically pair with any Google Home speaker through Bluetooth and show up in the Home app, making Assistant control almost as simple as screwing in the lights.
LED lights could get better with self-assembling particles
LEDs have dramatically transformed the lighting world over the past few years, thanks to their increased efficiency and life-span over past technologies. But LEDs could see even more upgrades with perovskite particles, a self-assembling nanoscale material that could make them even more efficient and cheaper to produce, Physorg reports. Researchers have already shown how perovskites could improve solar cells, but until now it was difficult to create uniform films made out of the material.
These LED bulbs are brighter despite fewer diodes and a lower price
One of the toughest parts to swallow of LED lighting technology is just how costly it can be. Well, the folks at Cree have taken umbrage with that and developed a bulb that'll retail for around $5 per 40- and 60-watt-equivalent bulb -- less than some standard CFL lamps by a few bucks. How's it doing that? In part by changing the bulbs' design and eliminating the need for heat sinks. As IEEE Spectrum reports, instead of the collar that more or less does double-duty holding the LEDs in place and dissipating heat, the new models get rid of hot air via convection. Meaning, as diodes get warmer, they naturally draw cool air in from outside the bulb as the higher temperature rises upward and outward.
Philips Hue gets down with app-controlled BR30 recessed lights
Philips' latest connected lighting product is taking aim at your recessed fixtures. The new Hue bulb, named BR30 to match the existing standard, screws into sockets typically pre-installed in kitchens, hallways and living rooms. They focus output in a beam, compared to the original Hue bulbs, which yield omni-directional light. That detail is the primary differentiator here -- functionality is identical, as is the price tag of $59 per individual bulb or $199 for a three-pack that includes a Hue bridge. As with their siblings, including the LightStrips and Bloom, you can control the LED BR30s from a smartphone, computer or tablet, letting you assign any color and brightness to individual bulbs. They're rated for a 15,000-hour lifespan, and Philips reports energy savings of up to 80 percent over conventional bulbs. You can pick up the BR30 beginning today from Amazon or Apple retail stores, while European customers can now order a GU10 version, which is more common in track lighting. That latter flavor will ship stateside in December.
Philips debuts iOS SDK for its light bulbs
No, that headline isn't a joke. You can tell we're living in the 21st century when even lightbulbs have SDKs. The new Philips SDK and APIs are for the company's Hue Connected lighting system. Hue lights are WiFi bulbs users can control with an iOS device. Philips is releasing an SDK and API for the lights because they recognized that several developers had backward-engineered the technology to control the lights with their own apps. Philips hopes that an official SDK will allow more developers to interface with their Hue lighting system. TechCrunch pointed out some examples of what developers might be able to accomplish with the SDK: The new developer program will mean that hardware makers using these standards can build in Hue-compatible features, so that the lights can be triggered by various actions. You could have a specific light recipe come on whenever you open the door, for instance, or when a thermostat is set to specific climate setting. Other potential uses of the developer tools include apps for amateur and professional photographers, which could help them optimize lighting for a shoot with a simple app attached to a device with light-level detection capabilities. Philips also plans to release future features around geo-fencing, scheduling and other smartphone sensor capabilities that could expand what developers can do with them. Interested developers can find out more about the SDK and API here.
GreenWave Reality ships WiFi-aware light bulbs that flick on through motion and smartphones
We've seen connected light bulbs before, some more sophisticated than others, but they're rarely as straightforward as GreenWave Reality's just-shipping Connected Lighting Solution. Eco-friendly LED bulbs in the lineup include support for WiFi and are immediately controllable from a smartphone or tablet as soon as they're receiving power. Basics controls like group presets and timed lighting are just the start; if you're not worried about leaving anyone in the dark, the bulbs can respond to motion sensors and only illuminate the rooms that need attention. And while the intelligence isn't new in itself, GreenWave would argue that sheer accessibility gives it an edge, with electric utilities in Denmark, the Netherlands and Sweden skipping the retail middleman by selling directly. Don't despair if you live in the US: the linked-up lighting is cleared for eventual use by Americans who'd like to save both energy and a trip to the light switch.
ARM forms UK group to foster an Internet of Things, put 50 billion devices online by 2020
ARM isn't content with dominating the mobile space. It's been by the far the most vocal about an Internet of Things where everything is connected -- and to make that happen, it just established an industry forum in the UK that it hopes will establish common ground for all those internet-linked light bulbs, refrigerators and thermostats. Home energy firm Alertme, cloud-aware sensing outfit AquaMW, lighting maker EnLight and white space wireless guru Neul will start meeting with ARM from August 24th onwards to hash out our automated, eco-friendly future. There's a certain urgency in this for the chip designer: it expects 50 billion devices on the grid by 2020. With IDC estimating a billion new connected devices just in 2011, the clock on that connected device transition is ticking very loudly.
Panasonic sends 100,000 LEDs down Tokyo river, mates tech with tradition (updated with video!)
If you'd been by the shore of the Sumida River in central Tokyo this past weekend, you would have noticed that it was glowing a distinct shade of blue. That's because Panasonic decided to kick off the first-ever Tokyo Hotaru (fireflies) festival by sending 100,000 EVERLED light bulbs down the river, both to mimic fireflies as well as to pay homage to a Japanese tradition of floating candles on the water. Before you cringe too much at the thought of the environmental impact, rest assured that Panasonic minimized the footprint of its aquatic LED parade. All the bulbs ran on solar power (presumably, charged during the day) that kept Evolta batteries fed inside, and the entire lot was scooped up in a large net afterwards. We love the exhibition as a large-scale demo of sustainable lighting -- you may just want to avoid fishing along the Sumida's shoreline for awhile in case you catch a straggler. Update: We've found a video of this spectacular event -- check it out right after the break.
Giinii AudioBulb hands, eyes and ears-on
Alright, so check this out -- that thing above is both a 5W LED light bulb and a 10W wireless speaker. Around the edge is a ring of glowing diodes with a four-stage dimmer, while the center is a 2.25-inch driver that speaks to a dock via 2.4GHz wireless. The AudioBulb from GiiNii is a fairly unique way to kick out the jams anywhere in your abode and they disappear into practically any lamp. A basic setup of two bulbs, a dock and a remote will set you back a surprisingly steep $299, but you can add on up to six more bulbs for $99 a pop. Speaking of rooms and bulbs, you can configure the speakers to work in stereo pairs or in mono, and set up two zones with different volume levels. The dock is a chintzy feeling piece of plastic with an integrated iPhone/iPod connector and around back you'll find an auxiliary jack for the non-Apple fans. The dock can connect to the speakers from up to 100 feet away, depending on the environment, and comes pre-paired with the bulbs in the box. Adding additional speakers requires just the push of a button on the base and bulb simultaneously to get the party started. It was tough to hear the tunes over the din in the hall at Pepcom's event, but we're confident it can't quite compare with the Play 3. They did, however, give off enough light to keep their little corner of the convention well lit. Check out the gallery below as well as the PR after the break. %Gallery-133815%
Sharp's energy-efficient LED ceiling lights are hip to be square
If you live in Japan and are looking to lower your household electricity bill, you might have to empty your bank account first. Sharp recently introduced its new line of ELM-branded LED ceiling lights and the highly energy-efficient, square-shaped bulbs won't come cheap -- retailing between 35,000 yen (about $456) and 55,000 yen (about $717). Pulling inspiration from the LEDs used in LCD televisions, the company was able to achieve an industry-leading 81.3 lumens per watt for the smallest of its three designs, and an average life of 40,000 hours for the entire lot . The energy-sipping set of overhead bulbs come housed in an insectproof shell, offering over 100-plus ambient light settings, controllable via remote. You can snag these utility-friendly lights on August 27th, just don't complain at the checkout when you see the price -- we warned you. Peep the video explanation after the break.
Bridgelux silicon LED could mean bright future for solid state lighting
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.
IKEA becomes the first major retailer to stop selling incandescent light bulbs
Remember The Energy Independence and Security Act of 2007 which mandated that all US retailers must stop selling incandescent bulbs by 2012? If you don't, you're apparently not alone, since according to a lighting survey conducted for IKEA back in 2010, 61% of Americans weren't aware of the legislation either. Luckily for those not in the know, IKEA was kind enough to remind the world of the upcoming change by proudly announcing that they've stopped selling the power-sucking bulbs a whole year early -- making them the first retailer in the US to comply with the bill. To help customers deal with the switch the furniture giant will sell visitors compact fluorescent and halogen bulbs -- in addition to LED lamps. That's seems like smart business considering the same lighting survey says 67% of Americans care about using energy saving lights, while 81% say using more efficient lights is a good environmental practice. So much for incandescent bulbs making a comeback eh?
GE closes last US factory making incandescent light bulbs
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.
Tea kettle concept almost boils your water with an incandescent light bulb
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."
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.
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]
LED traffic lights don't melt snow, do cause accidents
A number of cold weather American states are reporting their dismay at finding out that LED traffic lights are so energy efficient that they do not produce enough excess heat to dissipate any snow that covers them. It turns out, perhaps in an homage to bad engineering everywhere, that the inefficiency of incandescent light bulbs was previously relied upon to keep traffic signals unimpeded. The new LEDs do not achieve the same effect, which has resulted in a few accidents and even a death being blamed on obstructed traffic lights. Feel free to apply palm to face now. It's not all gloomy, though, as the majority of people are said to treat a dysfunctional traffic light as a stop sign (how clever of them), and a tech fix is being worked on as we speak.
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.
