FAQs

Yes. The DLLA4-UNV1-M2 is designed for universal input, supporting 120-277 VAC and 127/250 VDC, which simplifies multi-site deployments and reduces the need for multiple stock keeping units. This flexibility helps standardize lighting across facilities with mixed power networks while preserving lumen output and performance at 8000 lm.
The DLLA4-UNV1-M2 is rated for Hazardous/Classified Locations with Class I, Division 2 and Zone 2, along with Class II Division 2 and Class III. It also features a NEMA 4X enclosure and IP66/IP67 protection, aligning with NEC/CEC requirements and enabling safe operation in corrosive or explosive environments.
Plan for a 4 ft long fixture with a 3/4 inch entry size and glass lens. Use the flush mounting method to sit the luminaire close to the ceiling, minimizing glare and obstruction. Verify ceiling cutouts and mounting hardware compatibility, and ensure the 39 in length aligns with the installed ceiling grid for uniform appearance.
The DLLA4-UNV1-M2 delivers high reliability with 8000 lumens at 59 W and a copper-free aluminum body, reducing corrosion-related failures. The LED technology provides long life and low energy consumption, translating to fewer replacements, lower maintenance costs, and higher uptime in challenging environments.
Upgrading to this LED fixture yields energy savings from 59 W operation and high luminaire efficacy (135 lm/W) versus legacy lighting. Combined with extended life, reduced maintenance cycles, and standardization across sites, facilities typically realize lower operating expenses and improved asset uptime over the product life cycle.
