The Ideal Fluorescent Tube Replacement! In this project, Zenda's have been used, which are IP65 fixtures with a color temperature of 4000 Kelvin. These fixtures are waterproof, dustproof, and vapor-proof (IP65). Optional features include emergency lighting or a motion sensor (both are also possible). The Zenda Series is commonly used in parking lots, corridors, warehouses, factories, and the food industry.
