MTLx Pro is a transit tunnel LED luminaire engineered for 15-plus years of unattended service—an engineering standard designed to eliminate one full tunnel re-entry cycle over a 20 to 25-year capital horizon. Two light sources deliver two operating modes in one fixture: a 40W downlight module provides continuous NFPA 130 §1.4 egress path illumination in standard mode and ramps to full OSHA 1926 output in work mode, joined by a 12W linear uplight for ceiling and overhead equipment visibility. Activation via clearNET or magnet wand. IP66 housing, UL 1449 Type 4CA surge protection, ANSI C136.2-2023 verified. Made in the USA.
