the JCBL is highly configurable and delivers comfortable and uniform lighting from mounting heights up to
30ft. Gymnasiums, warehouses, packaging facilities and other industrial applications all benefit from JCBL’s
highly efficient design that saves up to 57+% over traditional sources. Certain airborne contaminants
