From Insteon website [emphasis mine]:
>"The INSTEON LED Bulb features simple setup, intuitive control and easy linking to any INSTEON controller, such as a handheld remote. When paired with the free INSTEON app, the SmartLinc Hub turns an iOS/Android smartphone or tablet into a fully functioning remote control of the bulb or an entire INSTEON network. The bulb is fully dimmable and can be added to any number of scenes to create custom lighting at the touch of a button.
The INSTEON LED Bulb contains INSTEON’s patented dual-band communication technology, the most reliable, efficient communication system available. Just like other INSTEON devices, the bulb acts as a network signal repeater and sends signals over both radio frequencies (RF) and a home’s existing wires (powerline).
The INSTEON LED Bulb retails for $29.99. For more information or to watch a demonstration video, visit www.insteon.com/bulb." //
