The EXL2-20 Series LED Edge-Lit Exit Sign features a contemporary design, built with dependability in mind. The sign is constructed using impact-resistant (optically clear) acrylic in a single-sided configuration. Bright LEDs illuminate the exit sign with exceptional light distribution and quality. The thin, edge-lit design saves space and reduces weight, making installation a breeze (considering it"™s usually done on a ladder). The EXL2-20 can be mounted from the top or end of the base. The adjustable base rotates 90° for easy installation on any surface. The EXL2 features an integrated nickel-cadmium battery to provide 90-minute emergency run-time if the power gets cut. Directional chevron arrows are included. Available in red or green lettering.
