Round and linear high bays can both work in industrial spaces. The useful comparison is the light distribution in your layout, with the racks, machinery, and working areas included.
Start with the room geometry
Record mounting positions, height, aisles, rack faces, workstations, and obstructions. The fixture shape gives only a rough indication of how it will light them. Use the actual optic’s photometric data.
Compare the proposed optics
A broad round distribution may suit an open floor. A linear or aisle optic may suit long storage rows. Either housing can be offered with several distributions, so compare the exact option in the quote.
Check useful light and operating conditions
Review maintained task illuminance, uniformity, glare, vertical light, temperature rating, ingress protection, and mounting. Compare complete-luminaire watts and lumens at the chosen setting.
Use a transparent comparison example
For 100 fixtures reduced from 400W to 150W at 4,000 hours per year, the power saving is 100,000 kWh. At $0.12/kWh, that is $12,000 annually before other costs. This is an example calculation, not a measured customer result.
Test sensor coverage at height
Check detection along and across aisles, delay settings, low-level output, and recovery time. Coordinate emergency routes and any continuously occupied areas with the control plan.
Compare installed options
Request layouts using the same room, targets, maintenance factor, and schedule. Include installation, access equipment, controls, commissioning, and expected maintenance in the cost comparison.
Frequently Asked Questions
Are UFO fixtures always better for high ceilings?
No. Review the optic, output, glare, and layout at the proposed mounting height.
Should I replace each old high bay with one LED?
Only if the new layout meets the task and distribution requirements. Compare the photometric result before fixing the count.
