The Rab Lighting RAIL high bay has always been a symbol of quality. We feetve maintained its aesthetics, its optics, and its performance and put it all in a package that's up to 40% smaller, drastically reducing its environmental impact. Available in five sizes/wattages, the RAIL can replace up to 1000W metal halide with a mounting height of up to 50 feet. Engineered with a high-transmittance lens for maximum light output, the RAIL also delivers a uniform, low-glare distribution that feets easy on the eyes. The Rab Lighting RAIL150N features include 150 watts equivalent to 400W metal halide, 4000K color temperature, 82 CRI, 120-277V 0-10V dimming, white finish, and V hooks mounting.
