While I’ve raved before about Philips’ L-Prize LED lightbulb it is about to have its socks blown off!  Enter the LIFX via an already successful Kickstarter project launch.  The LIFX will be one of the first major “Internet of Things” product that makes a significant impact on a large scale.  With the ability to have every LED light bulb networked, dim-able, and controllable by your favorite smart device it will change the game of current home automation and lighting energy consumption.

lifx-wireless-led-light-bulbThe Kickstarter product video gives you a good initial picture of what to expect from networking each and every lightbulb of your home.  It lightly hints at one of the major benefits - time savings.  The video demonstrates the ability to control the LIFX via the device you have but what we will see as we continue down this path is a blending of the control that the LIFX brings combined with the motion sensing of something like the Wemo or another proximity or biometric sensor.

While the different colors of the LIFX are neat they’ll provide the ability to have the perfect lighting in any situation.  LIFX uses a master/slave concept to connect to your home router via 802.11n and then onto all the other LIFX smartbulbs via IPV6 802.15.4 mesh network.  And once LIFX hits the streets the LIFX Software Development Kit (SDK) will croudsource some major innovations in automation!  Want the house setup to simulate sunrise and sunset - do it!  As far as the fading night light - awesome.  Have the ability to fade it off for the little one to fall asleep while ensuring the child is afforded the great sleep that a very dark room provides.  Need to walk through the house light your entire path before hand.

One thing is sure - these wireless lights are going to be a significant game changer for home lighting, home automation, and lighting energy consumption.

I’ve been much more interested in reducing energy, saving electricity and improving energy efficiency in homes from the moment I first heard Amory Lovins speak at the Defense Acquisition University (DAU) in the mid 2000’s.  From his inspiration I started reviewing my own life and focused its energy expenditures.  I started with household light bulbs.  In the pursuit to reduce our home electricity use and save on electricity and utility costs I immediately purchased numerous CFLs and started ensuring the old incandescent bulbs were removed and replaced.  What I found was that I was on the early end of the Technology adoption cycle and that many of these bulbs could not be used with dimmers, didn’t give off a similar warm light that the incandescent bulbs provided (which my wife hated!), and although the energy expenditure was less the early CFLs still left something to be desired.

Enter the Lighting Prize (L Prize) by the U.S. Department of Energy (DoE).  Wanting a Thomas Edison like transformation of illumination DoE set forth a challenge to competitively develop a new and exceptionally well crafted and tested LED light bulb.  Philips was the lighting contest winner.  They produced an exceptional product which is now known as the Philips 10-Watt Lighting Prize (L Prize) Award Winning 60-Watt LED Light Bulb.  The L Prize Light Bulb appears to have corrected the major issues that I experienced with the early CFLs.  However the useful lifetime of more than 25,000 hours, compared with 1,000 to 3,000 hours for the  incandescent products these highly efficient bulbs are intended to replace.   Yet the Philips L-Prize is still debuting as a $60 Philips light bulb.  But even in the couple of months since the bulb’s announcement and release the price has dropped on average 10% and is near an average of $50 for the Philips Bulb.

I’ve found the Philips 10-Watt L-Prize Award Winning 60-Watt LED Light Bulb in a couple key places; this will help you get the best deal!

I ran a quick comparision of a 60 watt incandescent and the L-Prize Bulb.  I’d with a few advantageous assumptions in the L Prize’s favor (made by their comparison tool) I’d recover the investment cost in approximately 1.1 years.  Either way I’m looking forward to getting one and testing it out (and see if the wife notices any differences!).
