High-output LED engine delivers 17000 lumens with 118 lm/W, providing bright, uniform illumination across large industrial spaces and reducing shadows that can impede visual inspections and operator safety. This translates to measurable business value through improved productivity and fewer rework incidents in manufacturing and logistics environments. The power factor of greater than 0.90 supports stable electrical behavior in facilities with large lighting loads, lowering energy waste and easing electrical design concerns for plant engineers. Broad voltage support of 120-277 Vac and 127-250 Vdc at 50/60 Hz enables a single luminaire family to retrofit multiple sites without complex voltage conversions, simplifying procurement and reducing spare-part inventories. The IP66 and NEMA 4X enclosure delivers robust protection against dust, water, and washdowns, cutting maintenance downtime in chemical processing, mining, and offshore facilities. Polycarbonate lens and aluminum housing provide strong impact and corrosion resistance, extending service life in harsh environments and reducing replacement costs. The SUM17L/UNV1 S903 is the equivalent luminaire to a 4-lamp T5HO, easing retrofits from legacy systems and enabling ballast-free or reduced-ballast upgrades for lower operating costs. Pauluhn Summit luminaire lineage is trusted in regulated industries, supporting compliance and steady performance under demanding conditions.

FAQs
The SUM17L/UNV1 S903 is designed for NEC/CEC Hazardous Location classifications (Class I, Division 2; Class II, Division 1) and carries IP66/NEMA 4X protection. Installers should follow standard wiring practices for hazardous-area luminaires, ensure correct voltage supply within 120-277 Vac or 127-250 Vdc, and mount per the product’s mounting provisions. Retrofit projects can leverage its 4-lamp T5HO equivalence to simplify ballast elimination or replacement during upgrades.
Key performance specs include 17000 lumens with 118 lm/W efficiency, 144 W power consumption, PF > 0.90, and operation at 50/60 Hz. Voltage compatibility spans 120-277 Vac and 127-250 Vdc, enabling flexible integration across multiple sites. The fixture’s LED design provides long life and reliable output in demanding environments.
Yes. Its Hazardous/Classified Locations rating (NEC/CEC), IP66 ingress protection, and NEMA 4X enclosure make it appropriate for oil & gas, mining, and other harsh environments where washdowns, dust, and exposure to chemicals occur. Its bright 17000 lm output improves visibility for critical tasks and inspections.
Certifications include NEC/CEC Hazardous Location ratings (Class I, Division 2; Class II, Division 1), IP66 ingress protection, and NEMA 4X enclosure. These certifications support regulatory compliance, reduce risk during audits, and simplify approvals for hazardous-area lighting projects.
The luminaire’s high lumen output with energy-efficient performance (17000 lm at 118 lm/W) lowers operating costs, while PF > 0.90 improves electrical efficiency. Long life and rugged enclosure reduce maintenance frequency, downtime, and replacement parts, delivering lower total cost of ownership in hazardous locations.
