Amazon takes up to 32% off a selection of Lutron dimmers and switches. Plus, it takes an extra 20% off any two or more items. Better yet, Prime members bag free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping starts around $6.) Deal ends May 14. A couple of eligible best bets, with prices before the extra discount:

• Lutron Maestro Motion 250W Single-Pole Sensor Switch for $19.97 (pictured)
• Lutron Diva Dimmable CFL/LED Dimmer Switch for $31.03
