Tunnel operators need lighting for motorists, cyclists and pedestrians that also minimizes energy costs and disruptive maintenance.TunLite LED is a LED-based luminaire for tunnel and underpass lighting. Its patented lens system allows a more efficient distribution than with conventional technologies. Luminance is the same while illuminance is lower which leads to less energy consumption. The optical concept also improves the spacing-to-height ratio. Light output can easily be adjusted and there is a choice of three different beams.Slim and pre-cabled, TunLite LED is easy to install, while its robust pure anodized housing, reliable LED sources and multiple drivers mean zero-maintenance.
