The 100W Smart LED Tunnel Light from E-Lite is designed to deliver high quality white light, luminous flux directionality and exceptional uniformity to create optimal visibility and comfort for tunnel and other underground passageway lighting. The luminaire features a modular architecture that is configured to accommodate E-Lite's proprietary LED light engines with Cree XT-E LEDs delivering 100 lumens per watt. The modular design of this tunnel light allows for easy maintenance and component replacement as well as future upgrade. Two 50 watt LED light engines provides 9199 initial delivered lumens which are comparable to a 250W HID lamp while using 60%–70% less energy. Each LED light engines is driven a universal voltage (100-277V 50/60Hz) Meanwell constant current driver with higher power factor and driver efficiency. UV stabilized acrylic lenses provide desired distribution optimized to get maximum spacing, target lumen and a glare-free lighting uniformity. The IP65 rated fixture are designed for all weather applications and dusty environment with perfect combination of heat dissipation and thermal conduction. E-Lite Smart is compatible with occupancy sensors, photocells or timers to harvest daylight to reduce energy usage and provide lighting control.
