High-efficiency LED performance drives lower energy costs and cooler operation, delivering 8000 lumens at 59 watts for substantial lighting upgrades in long-span runs; customers gain lower utility bills and improved worker visibility in production lines. The durable copper-free aluminum housing with natural finish, coupled with IP66/IP67 ingress protection and a NEMA 4X rating, ensures reliable service in damp, dusty, and corrosive environments—reducing maintenance frequency and replacement cycles for outdoor and indoor hazardous locations. An integrated surge protection module (>10 kV) shields critical electrical infrastructure from transient events, increasing system uptime and reducing unexpected repair costs in facilities with variable Power quality. The diffused glass lens provides uniform light distribution and glare control, enhancing safety and productivity, while the 4 ft form factor and 3/4 in entry size simplify wiring during upgrades and new installations. Ceiling/swivel mounting adds installation flexibility, enabling precise alignment in limited ceiling space and retrofit projects, and the broad 120–277 VAC, 50/60 Hz range supports diverse electrical architectures in industrial plants.

FAQs

Yes. The Champ MLLA series is designed for hazardous and classified locations and aligns with NEC/CEC standards, providing Class I, Zone 2 and related classifications to support operations in chemical processing, oil, and gas environments. For installation, verify the exact classification within your facility and follow all local codes, wiring practices, and UL certification guidance.
The fixture operates at 120–277 VAC and 50/60 Hz, with 127/250 VDC support in certain configurations. It uses 3/4 inch entry cables and is designed for ceiling or swivel mounting. The unit delivers 8000 lumens at 59 W with a power factor > 0.94, and includes integrated surge protection to guard against transient events.
IP66/IP67 ratings and NEMA 4X housing ensure ingress protection against dust, water jets, and corrosion, which translates to safer operation and longer service life in demanding locations. These ratings support compliance with hazardous-location requirements and enable outdoor and indoor installations without additional protective enclosures, reducing overall system cost.
The fixture offers ceiling/swivel mounting and a 4 ft length with 39 in overall engine length, enabling flexible aiming and straightforward mounting in tight or awkward ceilings. The 3/4 in entry and diffused glass lens support easy integration with existing conduit runs and provide uniform light distribution across large areas.
Expected benefits include reduced maintenance downtime due to long LED life, improved energy efficiency (59 W for 8000 lm), and protection against surges that can damage lighting circuits. With robust hazardous-location ratings and UL-listed documentation, facilities can meet regulatory requirements while lowering total cost of ownership through lower energy and maintenance expenses.
