Walmart offers the Philips Friends of Hue Bloom WiFi LED Bulb for $59.99. Opt for in-store pickup to cut that to $46.33. (Amazon has it for the same with free shipping.) That's the lowest price we could find by $14. This dimmable 12-watt bulb can be added to an existing Philips Hue bridge or other compatible bridge, which allows you to control your lighting via apps for iOS or Android.
