J&J Chemical offers two solar-powered motion-sensor lights designed for portable restrooms. J-Light 30 offers five super-bright, cool-white LEDs emitting 30 lumens with a 1.2-volt Ni-mh 900mAh rechargeable battery. J-Light 55 has eight super-bright, cool-white LEDs emitting 55 lumens with a 3.2-volt LiFePo4 1,200mAh rechargeable battery. Both are easy to install and fitted with a motion sensor to activate the light and day/night sensor so they will not activate in the daylight. They switch off after 40 seconds of inactivity. J-Light 30 requires a 1.5-inch hole, while J-Light 55 requires a 2-inch hole. 800-345-3303; www.jjchem.com.
