Linear LED High Bay Selection Guide

Where a round fixture spreads light evenly in all directions, a linear high bay concentrates it into a long rectangle, which is exactly what a racking aisle needs. Linear high bays sit alongside LED UFO High Bays in the LED High Bay Lights family: linear over the racking, UFO over open floor. For ceilings under 15 ft, move to LED Low Bay Lights; for the broader plant catalog, see Industrial Lighting.

Linear High Bay Output by Mounting Height

Mounting height sets the lumen package. Read your structure height across and the wattage follows.

Distribution, Color, and Controls

The rectangular optic puts light down the aisle and onto the rack faces instead of wasting it on the flue space. 5000K is the common warehouse choice for contrast; 4000K suits mixed retail and work areas. 0 to 10V dimming is near universal, and aisle occupancy sensors cut energy dramatically in low pick areas by dimming to standby until a forklift arrives.

Mounting and Swapping Fluorescent

Linear high bays hang from cables, chains, pendants, or a surface mount, and many offer continuous row mounting for an unbroken line of light. They are the natural one for one swap for 6 and 8 lamp fluorescent high output strips: keep the same spacing, drop the wattage by half or more, and gain instant on performance and a longer service life.

Yes. Most include 0 to 10V dimming and accept aisle style occupancy sensors that dim the fixtures to a standby level until motion is detected, which saves significant energy in low traffic aisles.

5000K is the common warehouse choice for its bright, high contrast light. 4000K is a softer neutral white that suits mixed retail and work environments.
