UFO vs. Linear LED High Bay Lights: A Selection Checklist
Compare mounting, light distribution, controls, and model specifications before choosing a high bay fixture.
Key takeaways
- Use fixture shape to build a shortlist, not to decide the final layout.
- Compare the exact model’s distribution, mounting hardware, electrical input, and controls.
- Bring a floor plan and mounting height to the discussion before fixing a quantity.
If you are comparing UFO and linear LED high bay lights, start with the space rather than a wattage target. The practical question is which combination of fixture, optics, mounting, and placement supports the work taking place below.
Compare the two formats
UFO high bays have a round body; linear high bays use an elongated housing. That distinction can help you compare physical fit and appearance, but the housing shape alone does not establish the light pattern. Ask for the photometric information for the exact model being considered.
| Decision | What to compare for either format |
|---|---|
| Mounting | Available mounting method, included hardware, fixture dimensions, and clearance. |
| Distribution | Photometric data, aisle geometry, obstructions, and intended task surfaces. |
| Electrical input | The model’s rated input range and the verified site supply. |
| Controls | Driver, dimming method, sensor model, and required accessories. |
| Environment | Location rating and temperature limits stated in the documentation. |
Shortlist by project conditions
For an open work area, record the positions of workstations and equipment before comparing arrangements. For storage aisles, add rack height, aisle width, and the surfaces workers need to read. Avoid assuming that a round fixture belongs only in open areas or that every linear model has an aisle-specific optic.
Send the same project brief to everyone preparing a proposal. Ask each proposal to identify the exact fixture and optic, planned mounting height, layout assumptions, and controls. This makes differences easier to evaluate than comparing fixture count alone.
Compare cost using the same scope
The U.S. Department of Energy identifies luminous efficacy as light output per unit of electrical input and discusses controls as an additional energy-saving opportunity. These are useful comparison factors, but they do not establish the savings for your building.
Keep a purchase comparison sheet with separate lines for fixtures, mounting accessories, controls, installation, and delivery. Record the operating-hour and electricity-rate assumptions behind any energy estimate. A lower purchase price and a lower operating cost answer different questions.
Questions before ordering
Can I replace every existing fixture one for one?
Treat one-for-one replacement as a proposal to verify. Ask whether the new model and placement address the actual work areas and any changes to racks or equipment.
Is wattage enough to choose a replacement?
No. Include light output, distribution, mounting, and compatibility in the comparison. Read our LED specification checklist before finalizing a model.
Use the same worksheet for both proposals
Before choosing a housing shape, ask each supplier to complete the same project comparison. Mark a missing answer as unconfirmed so it remains visible at the purchasing stage.
| Project input | UFO proposal | Linear proposal |
|---|---|---|
| Exact model, optic and photometric file | Record proposed equipment. | Record proposed equipment. |
| Mounting height, obstructions and task areas | Document layout assumptions. | Use the same site conditions. |
| Selected power and output | Identify the operating setting. | Identify the operating setting. |
| Sensor and mounting hardware | Separate included and additional parts. | Separate included and additional parts. |
| Fixtures per sales unit and units ordered | Calculate the total fixture count. | Calculate the total fixture count. |
For a concrete ordering example, the 150–240W UFO Audio Jack version lists 150W, 200W and 240W settings, fixed 5000K and one fixture per purchased unit. Its 2.5mm sensor base is included; the sensor head is separate. This describes that sales version only, and does not identify a matching linear replacement or establish equal light distribution.
Use the wattage and dimming comparison when specifying operating behavior, and the sensor-package checklist when completing accessory quantities.
