Additional Information

Typical Applications: Architectural commercial interiors, offices, conference rooms, retail environments, supermarkets, educational institutions, stairwells, and modern lobbies.

Mounting Capabilities: Supports pendant/suspension mounting, surface mounting, wall mounting, recessed mounting, or T-grid ceiling mounting with corresponding mounting kits (sold separately).

Controls Integration: Compatible with MaxLite c-Max Basic, Network, and EasyRF plug-and-play control nodes when installed with the optional c-Max sensor box (LM2-CMAXBOXB).

Continuous Run Notice: When joined via the press-fit connectivity system, overall continuous run length reduces by approximately 0.5 inches (12.7 mm) per joint due to the removal of adjoining end caps. When operating at the lowest wattage setting, maintaining dimming levels above 15% is recommended.
