Home Depot offers the Mr. Beams Indoor/Outdoor Motion Sensor LED Lights 2-Pack in White, model no. MB532, or Brown, model no. MB522, for $20.39. Choose in-store pickup to dodge the $5.99 shipping fee. (Amazon charges the same with free shipping via Prime.) That's the lowest price we could find by $5, although we saw it for $4 less a year ago. Each light features an auto-shutoff, 120 sq. ft. of coverage, and detection range up to 12 feet. This 2-pack requires six C batteries (not included). Deal ends April 16.
