FAQs
Plan for flush ceiling mounting with a 4 ft form factor and 39 in length. Ensure 3/4 inch entry wiring and a power supply within the 347-480 VAC range. The unit’s IP66/IP67 rating and NEMA 4X enclosure support harsh environments, while the hazardous location ratings (Class I, Division 2; Zone 2) guide proper mounting and wiring practices.
The fixture delivers 8000 lumens at 59 watts, achieving about 135 lm/W. This high efficacy reduces energy draw while maintaining bright, uniform illumination. In practice, facilities experience lower electricity costs per fixture and better lighting quality for operators, inspectors, and maintenance crews without increasing run times.
Yes. The MLLAN4-UNV34-S903D-WH-M2 is rated for hazardous locations, including Class I, Division 2 and Zone 2, with additional approvals for Class II and III configurations. It also carries NEC/CEC compliance and a NEMA 4X enclosure rating, supporting safe operation in areas with flammable atmospheres.
The fixture’s copper-free aluminum housing, diffused polycarbonate lens, and robust IP66/IP67 protection resist dust, water, and corrosive exposure, extending service life. A long-life LED platform with high PF reduces re-lamping frequency, lowering maintenance downtime and total cost of ownership in petrochemical, refining, and offshore facilities.
Compliance is supported by Hazardous/Classified Locations area ratings, NEC/CEC standards, IP66/IP67 ingress protection, and a NEMA 4X enclosure. These certifications provide assurance for offshore, marine, and other demanding environments, enabling safer operations, regulatory alignment, and smoother project approvals.
