TUNNEL LIGHTING

The Most Advanced Tunnel Lighting System in the World.

FOR TRANSIT, HARSH ENVIRONMENT, AND OTHER DEMANDING TUNNEL LIGHTING APPLICATIONS

The MTLx is the first light fixture designed to specifically address all modes of required tunnel illumination in a single form factor. Individual light level modes are controlled through the clearNET™ wireless mesh network, which also performs health/diagnostic monitoring on the electronic sub-components including light engine, driver, and optional battery.

DIMENSIONS

3-Function Lighting

Only 6-watts are required to comply with NFPA 130 emergency egress light levels at 3:1 uniformity to improve safety. Levels can be preset higher depending on agency requirement (e.g. 1 or 2 fc minimum). For maintenance and construction work periods, output can be changed to 50-watts to comply with OSHA 1926. The included 10-watt uplight component illuminates leaks and other potential damage/issues on the ceiling.


NFPA 130 Compliance

The optional integral battery back, which provides 1-4 hours of emergency lighting depending on requirement, meets the intent of NFPA 130 and eliminates the need for costly upgrades to two-hour fire rated emergency power circuits, associated junction boxes, and backup generators/inverters. System safety and performance is improved through redundancy at the fixture level with remote diagnostic health monitoring. Clear-Vu’s NiMH battery technology is world class and has a 10-year design life to diffuse any fears of battery maintenance.


Impervious to Physical & Environmental Abuse

Heavy gauge extruded aluminum construction, high impact-resistant lensing and tamperproof fasteners combined with an IP66-rated housing results in a lighting fixture that withstand extreme physical and environmental abuse.


clearNET™ Wireless Mesh Network Integration

clearNET monitors the health of the lighting system through a 900Mhz wireless mesh network to provide effective and efficient maintenance and asset management and is capable of integration with existing EAM software platforms. clearNET also provides the capability to control the level of illumination specific to activities in a tunnel. Additionally, clearNET serves as a platform to provide a power and data connection for non-lighting system sensors including ambient temperature, moisture, gas, and/or hazardous materials.

Tunnel Light Level Model VieW

MTLx provides high levels of uniform lighting for visual comfort and safety. Even at 25’ spacings the lighting system exceeds required lighting levels for emergency egress lighting, maintenance/construction task lighting and ceiling inspection lighting.

Illumination calculated using AGI32 v19.4. Typical tunnel profile: 16’-8” radius; 14’-4” height from track to highest point; 2x3’ walkway. 10% reflectance on tunnel walls and 0.70 Light Loss Factor. Illumination measured on center of walkway at 0’-0” elevation. Lights mounted 10’ high from track (7’high from walkway). *Clear-Vu Lighting can provide additional simulations based on specific customer light level requirements.

The MTLx is IP66 rated to ensure that the lighting fixture is dust-tight and water-tight.

IP66 is the highest-level particulate and water protection without entering the categories for submersible lighting fixtures.

The required 5 foot candles for working in OSHA 1926.56 can be efficiently met or exceeded with minimal power input.

Typical max/min ratios below 4:1 ensure uniform light that is conducive to safe and effective working.

MTLX: The Most Advanced Tunnel Lighting System in the World.

NFPA 130 sets the standard of 1 foot candle for fixed guideway transit and passenger rail systems.

This illuminance can be met at very low power input or with the optional battery.
