240W High Bay with Motion Sensor | Microwave Induction, 5000K

A high bay that runs itself

A microwave sensor in the housing detects movement and brings the fixture up to full output. When the area empties it drops back down. In a warehouse where half the aisles are empty at any moment, that is the difference between lighting the whole floor all shift and lighting the part of it somebody is standing in.

At 240W and 5000K it is a standard industrial high bay in every other respect.

Specification

Microwave or infrared sensing

For a high bay mounted 25 feet up in a cold store, microwave is the only one of the two that works reliably. That is why it is the standard on industrial fixtures.

Tuning the sensitivity

Set too high, the fixture triggers on a forklift two aisles away and never dims. Set too low, someone walking slowly does not register. Most sensors have an adjustment on the housing — set it during commissioning with people actually moving in the space, not from the specification sheet.

Where the saving comes from

A sensor pays for itself in a space that is occupied intermittently: storage aisles, plant rooms, loading areas, overnight shifts. In a manufacturing hall staffed continuously, it saves nothing and adds a component that can fail. Match the fixture to how the space is used.

Installation

Hardwired at 100 to 277V by a licensed electrician. Mount where the sensor can see the aisle, and commission the sensitivity before the lift leaves site.
