FAQs

The fixture supports 120-277 Vac with 50/60 Hz input and 127/250 Vdc options, offering flexible integration into common plant electrical systems. An integrated surge protection module (>10kV) helps guard against transients, reducing downtime and maintenance costs. This makes retrofits straightforward and reduces the need for power conditioning equipment, even in older installations.
It carries NEC/CEC standards and hazardous-location ratings such as Class I Zone 2, Class I Division 2, Class II Division 1, and Class III, along with a NEMA 4X rating. In addition, ingress protection is IP66/IP67. These certifications provide compliance for a wide range of hazardous and classified environments, including chemical plants and mining sites.
Yes. The Champ MLLA4CS-UNV1-S903-SRG1-M2 is a 39-inch long fixture with a 7.13-inch width and 6.57-inch height, designed for ceiling mounting with a swivel option. The 3/4-inch entry size supports versatile wiring configurations. Its length and mounting flexibility enable retrofit into many existing industrial layouts while maintaining high illumination coverage.
With 8000 lumens at 59W (approximately 135 lm/W), it reduces energy consumption compared with older luminaires. The integration of surge protection improves reliability in fluctuating power conditions, while the durable copper-free aluminum housing resists corrosion in harsh environments. Long LED life minimizes maintenance cycles, translating to lower total cost of ownership.
