What can you do with an LED light bulb that has its own internet address? And how much would you pay for it?
Those are some of the questions that GreenWave Reality and NXP Semiconductor are asking the $100 billion lighting market. On Monday, the two launched a new line of Wi-Fi-networked LED light bulbs, along with the Connected Lighting Solutions platform to run them.
GreenWave, a startup founded by ex-Cisco execs, has already started shipping the bulbs to European utility customers, including Seas-NVE in Denmark, Nuon in the Netherlands, and Fortum in Sweden. The new bulbs are also certified for sale in the United States, where a basic kit, containing a gateway device and four bulbs, along with a handheld remote, will cost about $200, GreenWave CEO Greg Memo said in a phone interview.
Individual bulbs run in the $20 to $30 range, Memo said — a reasonable price, compared to the Energy Star-rated, fully dimmable LEDs that might be seen as competition on the market. In Europe, on the other hand, utilities have already been supplying NXP networking-embedded LEDs to key customers as part of their energy efficiency initiatives, he said. Monday’s announcement means they can now add GreenWave’s energy management platform to support them as well.
Before you dismiss this idea of a $30 networked light bulb as an expensive experiment, bear in mind two factors. First, the rise of the “Internet of Things” is pushing basic IP connectivity down to pacemakers, security webcams, smart thermostats and other devices at a pace that should cut costs dramatically in the years to come.
Second, there’s a new breed of IPv6-enabled mesh networking technology that’s allowing these devices to receive and pass along data to one another, which beefs up the topological factors (i.e., walls) that can cause trouble for low-power wireless networks. Standards involved in this new IPv6 mesh networking include 6LoWPAN, which is part ofCisco’s new smart grid wireless networking technology being adopted by partners like Itron, Elster and Alstom. Most of North America’s smart meters deployed to-date run on mesh networks that have essentially proprietary technologies for the physical communications layer — that is, radios — that carry their data. Another standard under development, IEEE 802.15.4g, is meant to standardize those technologies, with big participants including Silver Spring Networks, Elster, Itron and Toshiba’s Landis+Gyr.
Inside homes and buildings, on the other hand, low-power mesh technologies ZigBee and Z-Wave are now vying for dominance, though it’s hard to call the competition definitive at this point — after all, the market is still in its infancy. But Wi-Fi is certainly part of that competition as well, with plenty of smart thermostat and home energy control devices offering Wi-Fi along with ZigBee, Z-Wave or other communications options. The Smart Energy 2.0 standard being developed in conjunction with the U.S. National Institute of Standards and Technology (NIST) will support Wi-Fi, ZigBee and powerline carrier HomePlug when it’s released next year — if it comes in on schedule.
Of course, lights are great places to add wireless mesh nodes, since they’re likely to reach every part of the home or business they’re deployed in, Memo noted. There are a host of smart lighting networking startups like Adura, Daintree Networks, Redwood Systems, Digital Lumens and Enlighted, to name a few, that are seeking to take advantage of that fact as well.
