Tanga offers the Bayit Home Automation Wireless LED Lighting Starter Kit, model no. BH1805, for $51.99 with free shipping. That's $3 under our mention from last March and the lowest total price we've seen. (It's also the best deal today by $3, although most retailers charge $63 or more.) The kit includes two color-changing LED bulbs and a WiFi bridge, which allows you to turn the lights on and off and control brightness and hue from your mobile device.
