GreenWave Reality ships WiFi-aware light bulbs
 

We've seen connected light bulbs before, some more sophisticated than others, but they're rarely as straightforward as GreenWave Reality's just-shipping Connected Lighting Solution. Eco-friendly LED bulbs in the lineup include support for WiFi and are immediately controllable from a smartphone or tablet as soon as they're receiving power. Basics controls like group presets and timed lighting are just the start; if you're not worried about leaving anyone in the dark, the bulbs can respond to motion sensors and only illuminate the rooms that need attention. And while the intelligence isn't new in itself, GreenWave would argue that sheer accessibility gives it an edge, with electric utilities in Denmark, the Netherlands and Sweden skipping the retail middleman by selling directly. Don't despair if you live in the US: the linked-up lighting is cleared for eventual use by Americans who'd like to save both energy and a trip to the light switch.
