MJ-3WL Waterproof Emergency Light

About the MJ-3WL Waterproof Emergency Light

MJ-3WL Waterproof Emergency Light provide bright, dependable egress marking for schools, offices, retail spaces, and healthcare facilities. Designed for fast installation and long-term efficiency, each unit operates on dual voltage 120–277V while consuming only about 3.5W, delivering crisp, legible legends without driving up energy costs. As part of our commercial indoor lighting portfolio, Sentinel supports diverse applications and is specified on projects nationwide. NCLTG engineers these exit signs for reliable, code-ready performance in professional environments.

In the event of a power outage, the integrated emergency battery supplies at least 90 minutes of illumination and fully recharges within 24 hours to meet life-safety code requirements. Options are available for both damp and wet locations, with rugged thermoplastic or aluminum housings built to withstand daily wear. Flexible configurations—red or green LEDs, single- or double-face signs, and versatile mounting methods—make it easy to adapt Sentinel signs to a wide range of building layouts.

For compliance and peace of mind, every Sentinel model is UL 924 listed and cUL certified, supported by a comprehensive 5-year warranty covering housing, electronics, and battery. The result is a reliable, low-maintenance exit sign solution that installs cleanly, meets code, and ensures paths of egress are clearly marked when it matters most.
