The solar-powered motion-activated J-Light from J & J Chemical 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 save time and money by not having to replace standard alkaline batteries, and are environmentally friendly. The motion sensor turns the light on when activity is detected. Once the restroom is exited or there is no longer activity, the light will remain on for 35 seconds then turn itself off. Five high-intensity LEDs emit 30 lumens of light. 800/345-3303; www.jjchem.com.
