The new Lithonia Lighting® Basics™ ECRG is a red / green switchable emergency exit combo that gives ultimate versatility in the field. The ECRG contains an internal switch on the LED board that allows you to switch between red and green. This product comes standard three-face, which includes an extra face plate with red and green inserts to change a single face sign to a double face sign. The ECRG comes standard universal mount – top, end or back mounting with snap-out and snap-in chevrons, making it the most field-configurable, universal emergency exit combo on the market today. Built from the previous ECR, ECG, and ECC platform, the new ECRG gives additional versatility but keeps the durability and dependability that has already been proven in the field.
