PIXTER lighting guides · Updated 10 October 2026
Choose warehouse high bay lighting around the tasks, mounting height, racking layout and required illumination. A larger wattage is not a substitute for a layout that controls shadows, glare and uneven light. PIXTER’s UFO high bay catalogue includes 50W, 100W, 150W, 200W and 250W options; the final choice depends on your site and the exact fixture specification.
What is a UFO high bay light?
A UFO high bay is a round LED fixture used as a starting point for high-ceiling indoor-lighting plans. Warehouses, workshops and production spaces can have very different needs: a storage aisle, packing bench and inspection area should not automatically receive the same fixture schedule.
Start with a site brief
- Building dimensions: length, width and the height at which fixtures can be mounted.
- Tasks and zones: storage, circulation, packing, production and inspection.
- Obstructions: racks, mezzanines, machinery, ducts and crane paths.
- Operating conditions: dust, moisture, ambient temperature and cleaning requirements.
- Existing installation: fixture positions, measured light levels and the issues you want to solve.
- Usage: working hours, daylight availability and control requirements.
How to compare 50W to 250W UFO high bays
The PIXTER catalogue lists five power options. Use these as a shortlist for comparison, not a ceiling-height prescription. A reliable selection needs lumen output, beam distribution, mounting height and a lighting calculation for the intended layout.
| Selection factor | What to ask | Why it matters |
|---|---|---|
| Power option | Which wattage and exact variant are quoted? | Connects the quote to the published specification. |
| Light output | What is the stated lumen output? | Helps compare fixtures beyond wattage. |
| Distribution | Is beam information or a photometric file available? | Supports a layout that accounts for racks and work areas. |
| Visual comfort | How will glare and bright sources be managed? | Considers people looking across aisles and workstations. |
| Environment | What are the IP and operating-temperature ratings? | Checks suitability for the building conditions. |
| Installation | What mounting hardware and clearances are required? | Checks the actual structure and fixing arrangement. |

A practical project example
Imagine a warehouse with tall racks along two sides and a packing area in the centre. Simply replacing every existing fixture with a higher wattage may leave rack faces shadowed while making the packing area uncomfortable. A better brief identifies the task zones, records fixture height, describes rack dimensions and asks for a layout covering both horizontal and relevant vertical surfaces.
Estimate electricity use without inventing savings
For a basic fixture-only comparison, daily energy in kWh equals fixture power in watts × number of fixtures × hours of use ÷ 1,000. For example, ten 100W fixtures operating eight hours use approximately 8 kWh per day at that stated power. Controls, actual input power and operating schedules can change the result. Compare with your existing installation and electricity tariff before estimating cost savings.
Questions buyers often ask
How many high bay lights does my warehouse need?
There is no reliable universal quantity based only on floor area. The task, mounting height, beam, rack positions and target illumination all affect the layout. Share a floor plan and ask for the proposed fixture positions and lighting calculation.
Is a 250W high bay always better than a 100W model?
No. Select a fixture that meets the layout and task requirements. Higher wattage can be unnecessary if the mounting, spacing or distribution does not suit the space.
Can UFO high bays be used outdoors?
Confirm the exact product’s environmental rating and mounting suitability. The high bay category alone does not establish suitability for exposed outdoor conditions.
Request a warehouse lighting quotation
Send the floor plan, mounting height, rack arrangement, delivery city, estimated quantities and operating hours. Mention whether this is a new installation or a replacement project. Send your project enquiry to PIXTER.
