Eaton Crouse-Hinds SUM13L/UNV1 S903 Summit Linear LED IP66

The SUM13L/UNV1 S903 delivers 13000 lumens from a 122-watt, 3-lamp T5HO configuration, achieving about 106 lm/W. This high output enables fewer fixtures for the same light levels, reducing capital expenditure and installation time in long runs such as assembly floors, conveyors, and maintenance corridors. The LED platform also provides consistent color and instant-on performance, a must-have for safety-critical areas where lighting reliability directly affects productivity. With a flexible voltage range of 120-277 VAC or 127-250 VDC and a PF > 0.90 at 50/60 Hz, the luminaire can be dropped into existing power systems without costly transformers, translating to easier retrofits and lower project risk while maintaining NEC/CEC power quality requirements. Installation compatibility is enhanced by Pauluhn Summit mounting practices and widely available replacement parts. The fixture is built for hazardous and classified locations, featuring IP66 ingress protection, NEMA 4X enclosure, and NEC hazardous ratings (Class I, Division 2; Class II, Division 1). These certifications minimize regulatory concerns and enable safe operation in chemical plants, oil refineries, and offshore facilities. Construction uses aluminum housing and a polycarbonate lens to resist impact, heat, and chemical exposure, while a 23.41 lb weight supports sturdy, vibration-resistant mounting. The design also supports straightforward maintenance with standard instruction sheets and a clear replacement-part ecosystem, helping maintenance teams plan service windows and budget for spares. In practice, the SUM13L/UNV1 S903 delivers predictable performance across a wide operating temperature range and steady illumination throughout the shift.
