SPARTAN MR series is one of the most versatile LED luminaires designed for industrial applications and rated for hazardous (Class 1 Division 2 and Zone 2), marine (UL1598A), and ordinary location use, the MR series is a robust light fixture with optimized features to withstand challenging environments.

Utilizing a copper-free and marine-grade aluminum alloy for the housing material, all electronics are well protected from environmental impacts and contaminants inside a pressure-equivalized IP66/67 rated enclosure. A multilayer powder coat prevents degradation of the alloy while allowing deployment in corrosive outdoor and indoor locations. Increased fin spacing promotes debris shedding as well as optimized airflow to maintain low operating temperatures for the internal power supply and LEDs.
