When GE introduced its latest C-series smart light bulbs, the focus was on affordability -- as they talked directly to your phone through Bluetooth, you didn't need a bridge device. That kept them out of touch of voice assistants, however, which meant replacing the whole lot if you wanted hands-free control. Well, you won't have to rethink your investment from now on: GE has introduced a hub, the C-Reach, that puts its bulbs on WiFi to enable support for Amazon's Alexa and (by the end of 2017) Google Assistant. As with most smart lighting kits, you can steer lights individually or in groups just by talking to your phone or a smart speaker.
