TechRabbit offers the refurbished Philips Hue White and Color Ambiance A19 60-watt Equivalent LED Smart Bulb for $49.99. Coupon code "TRPHIL25" cuts that to $37.49. With free shipping, that's $8 under the lowest price we could find for a new unit, although we saw it new for $11 less on Cyber Monday. Via the Philips Hue app and paired with the Philips Hue Bridge (sold separately), you can control this bulb remotely, including choosing from millions of colors and shades. Deal ends April 19.

Note: A 1-year TechRabbit warranty applies.
