Start with the space above the fixture.
High-bay selection starts with mounting height, floor geometry, environmental conditions, and controls—not a wattage shortcut. Use those constraints to narrow the form factor, then compare actual manufacturer families.
How high is the fixture plane above the working surface?
Open floor, narrow aisle, racking, production line, or mixed use?
Target light level, uniformity, task zones, and spacing.
Voltage, dimming, sensors, emergency, and connection method.
High-bay families available to research now
Open a current family to review wattage packages, lumens, CCT, voltage, controls, mounting, documents, and project configuration.

Linear and UFO are different tools, not styling choices.
Choose the geometry that fits the space, then compare output packages inside that family type.
Linear
Directional coverage along a long footprint
Check aisle geometry, mounting method, sensor location, and lens/distribution.
UFO / round
Compact fixture with broad area coverage
Check mounting height, beam option, controls, and high-voltage availability.
Vapor tight high bay
Sealed construction around the LED/driver assembly
Confirm actual location/IP rating and environmental requirements for the project.
Use photometrics when the result matters.
Two 30-foot warehouses can need very different fixtures because aisle geometry, reflectance, task requirements, spacing, optics, and obstructions change the result. Use wattage only as one input—not the design method.
Bring the constraints that cannot change.
The more of these we know, the less time the project spends bouncing between “almost right” fixtures.
If the space is wet, dusty, washdown, corrosive, unusually hot, or exposed to impact, tell us before we compare ordinary high-bay families.
