Amazon offers Prime members the Philips Hue Dimmer Switch for $24.99. Clip the $2.09 coupon on the product page to cut that to $22.90. Plus Prime members qualify for free shipping. That's the lowest price we could find by $2, although it was $5 less in June. This is a wireless switch and remote control in one and can connect up to 50 Philips Hue lights.
