Light tunnels with Holophane’s TunnelPass LED luminaires
By Alyssa Dalton
December 3, 2013 – Acuity Brands says its TunnelPass LED luminaires from Holophane meet the rigorous demands of any tunnel or underpass environment, while boosting lighting uniformity and colour rendering index (CRI) to improve visibility and safety for drivers who often travel at high rates of speed.
A segmented reflector system offers three light distribution options—ceiling mount counterbeam, ceiling mount long and narrow and wall mount crossbeam—to meet IES RP22-11 requirements either as a retrofit or for new construction. All drivers have 0V to 10V dimming capability, allowing the lumen output to be changed as required by a control system. According to the company, the LED fixtures decrease energy consumption by up to 50% compared to high intensity discharge (HID) fixtures and offer UL 40C wet location, IP66 and 3G vibration ratings.
