The best high bay is now better for the environment.

The RAIL linear high bay.

Even better than before.

The RAIL high bay has always been a symbol of quality. We’ve 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.

sustainable design.

The RAIL’s upgrade includes the elimination of coatings, which makes the high bays much more sustainable. The aluminum is shot blasted for a natural, chemical-free finish that drastically reduces hazardous waste and energy. In addition, some components are made with 30% recycled, Post Consumer Resin (PCR).

Optimized output.

Engineered with a high-transmittance lens for maximum light output, the RAIL also delivers a uniform, low-glare distribution that’s easy on the eyes.

Multi-level lighting control.

Factory-installed microwave and PIR sensors are available to maximize energy savings, as well as a Controller or Sensor to integrate with our Lightcloud lighting control system.

Battery backup option.

All models of the RAIL are available with a battery backup that can provide 90 minutes of emergency lighting.


The RAIL comes standard with V-hooks for chain mounting but pendant mount kits are also available.
