Utilitech LED light bulbs get cheap at Lowe’s

I don’t why, but it seems like I’m constantly changing light bulbs at my house. Normal incandescent bulbs last only a couple weeks in some of my lights meaning every other time I hit the switch it feels like I’m needing to pull out the stepstool and replace some bulbs. I would love to use LED-based light rather than the little florescent bulbs I’ve started using because I don’t care for the color of light they produce.

The problem is that most LED light bulbs are either too dim or too expensive for me to justify. Finally, LED light bulbs are beginning to come down in price and increase in brightness to the point where you can use them in your average light fixture. Home improvement center Lowe’s has a new line of LED bulbs sold under the Utilitech brand that are surprisingly affordable.

The company offers several different watt ratings under the Utilitech name including a 100 W equivalent. That 100 W equivalent bulb consumes 23 W of power and produces a warm white light color in the 3000K range. The bulbs are rather odd looking with a very large finned heatsink and the yellow protrusion where the LEDs are actually housed.

I’d like to see the bulb in a fixture to get an idea of how much of that is going to stick out or if it’s approximately the same size as a traditional bulb. With looks aside, the 100 W version sells for $34.98. That’s still pretty expensive, but it has a 25,000 hour lifespan meaning you won’t have to replace this bulb for years, in fact the manufacturer says 22 years. Perhaps even more appealing than the 100 W equivalent is a incredibly cheap 40 W equivalent sold under the same brand name that costs $9.98. That isn’t much more expensive than the small florescent lights on the market and you shouldn’t have to wait for an LED bulb warm-up the way you do a florescent bulb to get full light strength.

Greenwave Wi-Fi Controlled LED Light Bulbs: Screw & Play

LED light bulbs are becoming more common and affordable, but a company called Greenwave Reality made the energy-saving light source even cooler. The company’s Connected Lighting Solution is a kit that includes LED bulbs that can be controlled via a mobile app. It’s one more reason to keep your phone out of your kids’ hands.

greenwave reality wi fi led bulbs controlled lighting

While not nearly as cool and showy as LIFX wi-fi lighting, the Greenwave kit is all about convenience and energy savings for consumers.  You only need to screw in the bulbs to existing sockets and then plug in the adapter to your router. No complicated setup is necessary. You can then toggle or dim many bulbs at once using the remote control or the mobile app. No more fumbling for light switches in the dark (although you can still use the switches if you want to).

But it’s also a boon for electric companies. Aside from being cheaper than conventional light bulbs, the kit can keep track of their electricity consumption and other usage information. Which is why Greenwave Reality will sell the kit to the companies, and not to end users. Before you complain, know that each kit costs $200 (USD), and only includes 4 bulbs. The plan is for electric companies to buy the kit from Greenwave Reality and then sell them to consumers at a subsidized cost. Everybody wins. Except the old light bulb, that is.

GreenWave Reality ships WiFi-aware light bulbs that flick on through motion and smartphones

GreenWave Reality ships WiFi light bulbs that flick on through motion and smartphones, join the 21st centuryWe’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.

Bluetooth Bulb lets you switch on, time, dim and color your lighting from your phone (video)

Bluetooth Bulb lets you switch on, time, dim and color your lighting with your phone video

Every once in a while, someone tries to give the humble light bulb a little next-gen flavor. This time, we’re adding Bluetooth 4.0 to the mix. Why, you ask? Good question, and one with a simple answer. The Bluetooth Bulb lets you pair your phone with one or more of the lights in your home, and then control them via an app. Switch them on, off, change brightness, set a timer, and a special RGB bulb even lets you change the color ambiance. If you’re worried about the cost and waste when these things burn out, fear not, as apparently every part is replaceable — and as there’s no home automation system involved — you won’t need anything else to get set up. If this idea switches you on, you might have to hold out a little longer, as the product is just a patented prototype right now. Sights are set on mass production, but you’ll have to stick with your old clapper for the time being.

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.

Levitating light bulb can power itself wirelessly

If you are interested in things that hover and fly, how about a levitating light bulb that can also power itself wirelessly? An electrical engineering student from the University of Queensland was able to develop a prototype of a levitating light bulb. Chris Rieger worked on the project for 6 months, combining previous researches conducted by other individuals. Rieger’s levitating light bulb is a combination of a magnetic wireless power transfer system and a magnetic levitating control system.

Rieger said that the most painful part of the project was the wireless power transfer functionality. He built an oscillator and a wireless power receiver circuit, which is a simple LC circuit tuned at exactly 1Mhz. Wireless power transfer is facilitated by a single large hoop of wire driven by alternating current at 1 MHz. This part of the system pulls 0.5A at 12V, bringing the whole of the consumption in at around 9 Watts. Then, a permanent magnet on the light assembly is used to levitate the light bulb. You can check out his fun project here.

How many engineering students does it take to build a floating light bulb? Just one. University of Queensland student Chris Rieger combined magnetic levitation and wireless power transfer like peanut butter and jelly to create a fancy floating sandwich. And by sandwich I mean light bulb.

Rieger says he’s working on a much better version of the bulb, one that will have a built-in dimmer and height control. Drop a comment on YouTube if you’re interested in buying that improved model to help Rieger decide if it’s worth making multiple units.
