Engineered for reliability and durability even in the toughest environments, Jinghong's LED tunnel lights come from the combination of years of experience in tunnel lighting and the application of the latest solid state lighting technologies. Available in 100W,150W,200W,240W, this tunnel luminaires are designed to deliver most comfortable ambient luminance and provide the driver with safe access into the tunnel interior. Specialized tunnel optics provide high uniformity and improved vertical light distribution, optimize photometrics to avoid black-hole and flicker effect in either probeam or counterbeam orientation, minimizing losses for refraction and reflection inside the optical system, and complements the automobile headlight system to maximize visibility through positive contrast. The luminaire takes advantage of 4 x 60W Bridgelux COB LEDs that deliver high lumen density for exceptional beam control and precision lighting. The high performance Meanwell LED driver operates to specification under wide temperature and electrical ranges to ensure reliability for the most rugged applications. The high strength housing is made of low copper die cast aluminum electrostatically sprayed with a polyester powder paint finish. The fixture carries an IP65 rating and will be resistant over time to dirt, dust, moisture, maintaining product performance unaltered even within in the toughest enviroment.
