A few years ago it might have been laughable to consider reviewing a light bulb, and it would have been even weirder to consider that the review would have to cover a setup process that included configuring a gateway and an app on a mobile device. These days, just about every device can be connected and the electronic devices in your home are probably all available in a 'smart' version.
This review is going to cover OSRAM
Sylvania's Lightify LED tunable white light bulb and their Lightify gateway. The bulb itself looks very much like a typical LED light bulb, but it can be controlled via a mobile app in order to turn it on/off, tune the light output from 2700-6500K, and to dim it. The Lightify gateway is one way to access the bulb from a WiFi network (or the Internet), but it is Zigbee compatible and devices from Wink, WeMo, SmartThings, and Nest all have provisions for controlling Lightify products.
Before taking a look at the items provided for review, let's cover some published data on the bulb and the gateway, as taken from the Sylvania website...
