FAQs

The MLLAN4-UNV1-S891-P-M2 uses the Champ MLLA lineage's flush ceiling mounting with a 39 in housing and 3/4" entries, aligning with standard Champ MLLA installation practices. It fits contiguous runs and retrofits where space is tight, reducing ceiling disruption while preserving optical performance. Optional accessories and conduit options remain compatible, and installation crews can rely on familiar mounting patterns to minimize training and risk.
This fixture delivers 8000 lumens at 59 watts, for 135 lm/W, with a power factor above 0.94, ensuring efficient operation at 50/60 Hz. It supports universal voltage from 120 to 277 VAC and 127/250 VDC, enabling reliable performance across multi-site facilities without rewiring. The wide optical distribution minimizes dark spots, improving productivity and safety.
Yes. It is rated for Hazardous/Classified Locations with NEC/CEC compliance, including Class I Zone 2; Class II Division 1; Class III. The enclosure meets NEMA 4X and IP66/IP67 ratings, providing protection against dust, water jets, and corrosion in challenging environments such as chemical plants, offshore rigs, and petrochemical processing facilities.
Common challenges include ceiling access, conduit entry alignment, and matching mounting patterns across legacy MLLA fixtures. The MLLAN4-UNV1-S891-P-M2 uses 3/4" entry points and a 39 inch housing for straightforward alignment, and flush ceiling mounting minimizes protrusions. Field crews benefit from documented installation sheets and compatibility with standard Champ MLLA hardware, reducing training time and on-site risk.
With robust construction and low energy draw, expected ROI improves through reduced energy bills and extended replacement intervals. The IP66/IP67 and NEMA 4X enclosure withstand harsh environments, decreasing maintenance frequency, while the neutral white output maintains visual clarity for operator tasks. Over the fixture’s life, energy savings and fewer maintenance calls translate to lower total cost of ownership.
