Tunnels and underpasses present a very sophisticated and demanding set of application requirements for even the best of lighting designers. At Acuity Brands, we can provide decades of experience in tunnel application design from industry leading brands such as Holophane®. Shutting down tunnels to perform costly ballast changes and relamping is extremely difficult and expensive to say the least. Products like the TunnelPass LED™ can provide 400 to 1000 watt solutions with an expected life of 20 years while providing substantial energy savings and maintenance reduction over traditional HID lighting systems.
