Tunnel lighting ranks among the most challenging of lighting applications. Not only does the intricate topology of a tunnel, with its “Black Hole” effect and critical transition zones require painstaking attention to detail, but also the tough, corrosive atmosphere caused by a combination of pollutants, moisture, chemicals, and galvanic couple differences (electrolytic ionization) add to the challenge. Luminaires installed in this type of environment can deteriorate rapidly causing unsafe tunnel conditions. Reliable lighting designed to last for many years is critical, especially in an area where access is restricted and minimal maintenance is a must. For these reasons, Kenall tunnel luminaires have been designed with your needs in mind, including stainless steel housings that last for decades and optimal light levels to ensure the safe flow of traffic throughout the tunnel. Our new LuxTran ™ LED luminaires are more powerful than their predecessors with lumen outputs ranging from 8,531 to 90,295—more than enough to obliterate the “Black Hole” effect—and LED life times up to 150,000 hours. Because tunnel lighting must endure the most challenging environmental conditions, Kenall has applied over 50 years experience in designing, testing and manufacturing luminaires to meet and exceed the highest industry standards, including ANSI, CSI and NEMA, so you can specify Kenall tunnel luminaires with complete confidence.

Built & Tested to Exceed Industry Standards Kenall delivers tough tunnel lighting systems designed and manufactured in the USA that are built and tested to meet or exceed industry standards. • Stainless Steel Kenall’s LuxTran ™ series is specifically designed and manufactured to eliminate corrosion and last for decades. Using only 316 and 304 stainless steel, typically used in marine environments, our tunnel products resist corrosion, rust and staining. • Passivated Welds With forming and fabrication being two of our key competencies, Kenall ensures that all welds on LuxTran products are passivated; restoring a uniform chromium oxide film on the material’s surface to eliminate the potential for corrosion or rouging. • Custom Mounting Bracketry Unlike many products in the industry, mounting brackets on Kenall’s LuxTran products can be customized to your unique tunnel characteristics. • Minimal Maintenance Kenall’s LuxTran LED luminaires provide longer L70 life times — up to 150,000 hours — lasting 5x longer than traditional tunnel luminaires for reduced operating cost and maintenance. • Tested to Meet Certified Performance Standards Kenall LuxTran luminaires go through many rigorous testing procedures to meet the following industry standards: ANSI C136.27-2012 temperature cycling/100 PSI water test, C136.31 vibration testing, UL1598/A, CSA22.2, NEMA 4X rating, IP66 rating per IEC 60598, as well as IESNA LM-79-08 standard photometry testing. See page 18 for a list of Kenall’s standard testing procedures. – Uniform luminance throughout tunnel interior – Generally low contrast values – Maximizes wall luminances – Maximizes candlepower to walls – Uniform luminance throughout tunnel interior – Generally low contrast values – Maximizes flux parallel to traffic flow – Maximizes candlepower to vehicle Symmetric EG 2012 Symmetric EG 2012 Light that radiates at right angles to the axis of the tunnel, directing it evenly to the walls Light that radiates parallel to the axis of the tunnel, distributing it parallel to the traffic flow Transverse Lighting www.kenall.com P: 800-4-Kenall F: 262-891-9701 10200 55th Street Kenosha, Wisconsin 53144, USA These products comply with the Buy American Act and may be covered by patents found at www.kenall.com/patents.

This is the point where adaptation begins. Approach During daytime hours, drivers’ eyes may have to adapt from over 10,000 footcandles to less than 1% of that level very quickly, while traveling at a high rate of speed. To facilitate this, the design must include the approach, which extends from the point that the tunnel opening becomes the principal feature in the driver’s field of vision (also known as the adaptation point), to the actual entrance of the tunnel. Adaptation Distance The adaptation distance is the distance between the adaptation point and the portal. (The portal is the plane of entrance into the tunnel, where the roadway changes from uncovered to covered.) Threshold Zone The first phase of visual adaptation occurs in the Threshold Zone as the driver enters the tunnel. The lighting levels in this zone are specified in CIE 88 2004, and depend upon the length of the tunnel, the Average Annual Daily Traffic (AADT), wall reflectances and whether cyclists are present or the exit is visible. The human eye requires more time to adapt from brightness to darkness than the reverse. For this reason, tunnel lighting must gradually transition to interior light levels. During nighttime hours, the area outside the tunnel is dark, whereas interior levels Refer to ANSI/IES RP-22-11, Section 7.0 for complete lighting application techniques.

Product speci cations are subject to change; please consult www.kenall.com for current product details. Transition Zone The second zone inside the tunnel is the transition zone, in which ambient illumination decreases from the relatively high levels found in the Threshold Zone to the lower levels found in the Interior Zone. In this zone, the light levels are decreased in stages, allowing the driver’s eyes time to adapt. The total length of the Transition Zone may be equivalent to 25 seconds of travel time. Interior The Interior Zone is comprised of the light level required for the remainder of the tunnel, once eye adaptation has been completed in the preceding Transition Zone. Exit Zone The Exit Zone is not a requirement as per ANSI/IES RP-22-11. The eye’s ability to adapt from dark to light occurs very quickly, although higher light levels are sometimes specified to help adapt back to higher exterior illuminance levels. Exit Zone lighting may or may not be required depending on local codes and practices. Negative Contrast (Counter-Beam) Positive Contrast (Pro-Beam) Types of Tunnel Lighting: Asymmetrical Light Distributions for Tunnels are similar to those of an illuminated open roadway; making the transition minimal. Tunnel lighting is comprised of distinct zones, each with unique lighting needs as illustrated below. For a detailed explanation, refer to ANSI/IES RP-22-11, Section 2.0.
