Amazon offers the Philips Hue BR30 LED Smart Bulb in White Ambiance for $33.49. For Prime members only, it drops to $26.79 at checkout. With free shipping, that's tied with last week's mention and the lowest price we could find by $3 today. Features include up to 50 shades of light and the ability to connect to smart wearable technology to turn the light on and off. Deal ends May 18.
Note that if you're buying more than one, it's a better deal to select the 2-Pack for $46.20 ($23.10/bulb.)
