Champ MLLA LED Linear
Feature → Business Impact → Application: The Champ MLLA LED linear fixture delivers 8000 lumens at 135 lm/W with a 59 W draw, enabling meaningful energy savings and reduced cooling load in hazardous facilities. This translates to lower operating costs across industrial plants while meeting demanding illumination standards in Class I, Division 2 and Zone 2 environments. Application-wise, it suits process areas, chemical plants, and oil and gas facilities where reliable performance and regulatory compliance are critical. Feature → Business Impact → Application: The copper-free aluminum housing coupled with a painted gray epoxy finish provides exceptional corrosion resistance in harsh environments, minimizing maintenance cycles and extending service life in outdoor and indoor hazardous locations. This design choice supports retrofit projects and new builds alike, reducing total installed cost over the lifecycle of the system. Feature → Business Impact → Application: The wide optical distribution with a diffused polycarbonate lens ensures uniform light, decreasing shadowed zones and improving worker safety in high-risk areas. In practice, facilities see improved productivity and reduced error rates in work areas that demand consistent illumination. Feature → Business Impact → Application: The 4 ft length with flush ceiling mounting and 3/4" entry supports flexible installation in restricted ceilings and tight mechanical spaces, easing retrofits in existing industrial layouts while maintaining a clean ceiling profile. Feature → Business Impact → Application: Compliance and safety are reinforced by IP66/IP67 ingress protection, NEMA 4X enclosure, and NEC/CEC standards, helping pretover to meet regulatory requirements and avoid costly rework during audits and commissioning. Feature → Business Impact → Application: The product’s wide voltage rating of 347–480 VAC and 50/60 Hz compatibility simplifies electrical design, reduces the need for multiple variants, and accelerates project delivery in global facilities with varying power networks. Feature → Business Impact → Application: Maintenance resilience is enhanced by a robust diffuser and lens material (diffused polycarbonate) that resist impact and discoloration, maintaining luminous performance over time even in demanding environments. Feature → Business Impact → Application: The strong warranty-like expectations are supported by UL-listed Canadian certifications and installation literature, enabling faster approvals and smoother procurement cycles for hazardous-area projects. This integrated approach reflects real-world industry requirements for durable, compliant, and measurable lighting performance.

FAQs
This fixture is designed for Class I, Division 2 and Zone 2 environments with NEC/CEC compliance, IP66/IP67 protection, and NEMA 4X enclosure, enabling flush ceiling mounting and 3/4" conduit entries for straightforward retrofits and new installs.
Key specs include 59W power consumption, 8000 lumens, 135 lm/W, 347–480 VAC input, and 50/60 Hz frequency. The high PF (>0.98) supports efficient electrical performance and stable operation in demanding facilities.
Yes. It meets NEC/CEC standards for hazardous locations and carries Class I, Division 2 and Zone 2 ratings, ensuring safe operation in compliant installations within chemical plants and similar environments.
The copper-free aluminum housing with a painted gray epoxy finish offers corrosion resistance, and the diffused polycarbonate lens maintains optical performance. These features reduce maintenance downtime and replacement frequency in harsh environments.
Energy savings from 8000 lm at 59W, reduced maintenance due to durable construction, and fewer replacements in hazardous areas collectively contribute to a favorable TCO. The IP66/IP67 rating and NEMA 4X enclosure further minimize downtime and audit risk.
