RAB RBAY15 Field-Adjustable Linear High Bay — 400/320/260/220/160/130/100/80W Selectable — 3500K/4000K/5000K — 120-277V/480V — White
The RAB RBAY15 is a field-adjustable linear high bay available in three ordering configurations — RBAY15S, RBAY15M, and RBAY15L — delivering documented output up to 61,882 lm across 400/320/260/220/160/130/100/80W selectable wattage steps and 3500K/4000K/5000K selectable color temperatures. It operates on 120-277V or 480V input, dims via a separate 0-10V dimming circuit down to 10%, and is UL Listed as suitable for damp locations. Each configuration is DLC Listed at the Premium tier. Its standout feature is a field-rotatable optic that switches between 90°/90° general-area distribution and 45°/110° aisle-focused distribution without changing fixtures.
Key Features

Lens & Optics
The RBAY15's field-adjustable optic rotates 180 degrees between two documented beam patterns.
- 90°/90° Beam: General-area, wide-floor distribution.
- 45°/110° Beam (rotated): Narrow-aisle and racking-focused distribution.
Smart & Control Features
The RBAY15 includes a built-in sensor port compatible with standard PIR/MVS occupancy sensors or Lightcloud Blue-enabled PIR/MVS sensors.
- Standard PIR/MVS occupancy sensors (sold separately)
- Lightcloud Blue-enabled PIR/MVS sensors for Bluetooth Mesh wireless control via the Lightcloud Blue mobile app (sold separately)
- MSR1 Multi-Sensor Remote Control for adjusting settings on non-Lightcloud Blue sensors (sold separately)
Lightcloud Blue uses RAB's Rapid Provisioning technology to commission devices without a gateway or hub.
