FAQs

The DLLA4-UNV1-S903-EM1-P-M2 is designed for flush ceiling mounting with a 39 inch length and a 3/4 inch entry size. Its copper-free aluminum housing and polycarbonate lens support rugged indoor or outdoor installations, while the 4 ft form factor fits common industrial ceilings. For installation, ensure proper clearance for the integrated emergency battery and prepare raceways during wiring on 120-277 Vac circuits. The weight is 23.5 lb, so use appropriate mounting hardware and supports rated for hazardous locations.
This luminaire is rated for Hazardous/Classified Locations with NEC/CEC standards compliance, including Class I Division 2 and Zone 2, Class II Division 2, and Class III. It also carries a NEMA 4X rating and IP66/IP67 protection, making it suitable for environments with dust, water exposure, and washdowns. When pairing with control gear, verify compatibility with 50/60 Hz supply and ensure installation adheres to local electrical codes.
Yes. The fixture’s IP66/IP67 protection, NEMA 4X rating, and hazardous-location approvals (Class I Div 2, Zone 2) make it ideal for offshore platforms and chemical processing facilities. The polycarbonate lens, copper-free aluminum housing, and epoxy gray finish resist corrosion and moisture. Its flush ceiling mounting and integrated emergency battery back-up support reliable operation during power interruptions in hostile environments.
The integral emergency battery back-up maintains illumination during power outages, enabling safe egress and continuity in critical areas. This reduces downtime, supports code-required life-safety provisions, and lowers risk-related costs. The long-life LED design reduces maintenance cycles, while energy efficiency (8000 lm at 59 W) lowers ongoing electricity expenses, contributing to a favorable total cost of ownership in hazardous locations.
Verify lumen output (8000 lm), power (59 W), color temperature (Cool white), voltage range (120-277 Vac, 127/250 Vdc), frequency (50/60 Hz), lens material (polycarbonate), and finish (painted gray epoxy). Confirm ratings IP66/IP67, NEMA 4X, and hazardous-location approvals (Class I Div 2, Zone 2, Class II Div 2, Class III). Also ensure the 3/4 inch entry size and flush ceiling mounting fit your ceiling and wiring space.
