FAQs

When installing the DLLA4-UNV1-S903-M2, ensure flush ceiling mounting in area classifications of Hazardous/Classified Locations. Use 3/4" entries for conduit connections and verify 120-277Vac or 127/250Vdc supply compatibility. Confirm that wiring methods and junction boxes meet NEC/CEC requirements and that mounting hardware is rated for Class I Division 2 or Zone 2 environments. The 39 inch length should be factored into mounting clearances and clearance around the luminaire for heat dissipation and maintenance access.
Key specs include 8000 lumens output at 59 watts with an efficacy of 135 lm/W, cool white color temperature, Polycarbonate lens, 4 ft length, and a wide optical distribution. It operates at 50/60 Hz with a voltage range of 120-277 Vac or 127/250 Vdc, and features a flush ceiling mounting arrangement with 3/4 inch entry. The unit is copper-free aluminum with a natural finish for durability in harsh environments.
Yes. The fixture is designed for Hazardous/Classified Locations with NEC/CEC compliance and hazardous ratings including Class I Division 2 and Zone 2, Class II Division 2, and Class III. It also carries IP66/IP67 protection and a NEMA 4X rating, making it suitable for wet, dusty, and corrosive environments commonly found on offshore platforms and chemical plants.
The DLLA4-UNV1-S903-M2 meets NEC/CEC standards for hazardous locations, carries Class I Division 2 and Zone 2 (as well as Class II Division 2 and Class III) ratings, and is certified with IP66/IP67 protection and NEMA 4X.
