Amazon offers its Prime members the Fulcrum Light-It Wireless Motion Activated 6-LED Porch Light in Silver, model no. 20031-301, for $18.12 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $7.03. It's also available in White for a few cents more.) That's tied with our mention from a week ago and the lowest price we could find by a buck. It features six glare-free LEDs, 25-foot motion detection range, and 30-second auto shutoff.
