The solar-powered, motion-activated J-Light from J&J Chemical Co. is a dependable light source that easily installs in the roof through a 1 1/2-inch hole. The self-contained solar panel acts as a day/night sensor — saving energy during the day and charging the batteries, allowing the light to activate only when it’s dark. The long-life rechargeable batteries don’t require constant replacement like standard alkaline batteries and are a more environmentally friendly solution. The motion sensor turns the light on when activity is detected. The light remains on for 35 seconds after the unit is used and turns off. Five high-intensity LEDs emit 30 lumens of light. 800/345-3303; www.jjchem.com.
