High-lumen LED output delivers 25000 lumens at 115 lm/W from 217W; this improves facility productivity by reducing fixture counts and lowering energy costs, especially in large-area production halls and outdoor-wastewater treatment zones. Universal voltage support of 120-277 VAC and 127-250 VDC simplifies global deployments, streamlining procurement and minimizing on-site engineering. The IP66 ingress protection and NEMA 4X enclosure provide rugged, corrosion-resistant performance in chemical plants and offshore facilities, ensuring reliable operation in harsh environments. The aluminum housing with a polycarbonate lens combines durability with transparency, enhancing heat management and long-term luminosity. The 6-lamp T5HO equivalent design supports retrofit strategies, enabling seamless replacements without substantial rework. A steady power factor >0.90 reduces electrical losses and supports compliant energy management programs. Installation instructions and literature support fast, safe commissioning and standardization across sites.

FAQs
SUM25L/UNV1 S903 is engineered for Class I, Division 2 and Class II, Division 1 environments with NEC/CEC compliance and IP66/NEMA 4X protection. It supports universal voltage (120-277 VAC, 127-250 VDC) for global installations and can be retrofitted using a footprint compatible with 6-lamp T5HO luminaires. For new builds or retrofits, refer to IF 1824 instructions for straightforward mounting and wiring.
The luminaire delivers 25,000 lumens at 115 lm/W from a 217W input, with a 50/60 Hz operating range. It runs on 120-277 Vac or 127-250 Vdc and provides a PF greater than 0.90. The lens is polycarbonate and the housing is aluminum, designed for durability in demanding industrial settings.
Yes. With IP66/NEMA 4X protection and NEC/CEC hazardous-location ratings, the SUM25L/UNV1 S903 is well-suited for oil and gas environments. Its 6-lamp T5HO equivalent footprint simplifies retrofits, and universal voltage reduces the need for voltage-specific hardware during replacement.
This luminaire carries NEC/CEC compliance for hazardous locations, with Class I Division 2 and Class II Division 1 ratings, along with a NEMA 4X enclosure and IP66 ingress protection. Canadian certifications and UL listings are reflected in the included installation literature and UL/CSA documentation linked in the product downloads.
The combination of 25,000 lumen output, 217W efficiency, and a PF >0.90 translates to lower energy costs and fewer fixtures required for large areas. The robust aluminum housing and polycarbonate lens, plus hazardous-location ratings, reduce maintenance and replacement frequency in harsh environments, delivering a favorable total cost of ownership over many years.
