LED Troffers vs LED Panel Lights: Differences, Uses & Which to Choose

If you are upgrading your warehouse lighting, one question can quietly cost you thousands over time. Should you go with UFO high bay LED or linear high bays? It sounds like a simple choice, but the wrong decision can mean wasted light, higher bills, and poor visibility where it matters most. 

Nothing But LEDs has helped facilities across the USA make this call, and here is exactly how to think through it.  This complete guide breaks it down in a way that actually helps you make the final choice between UFO high bay and LED linear high bay. 

UFO High Bay Lights Explained

LED UFO High Bay lights are compact, circular fixtures designed for high ceiling LED light environments. Their shape is not just aesthetic. It helps distribute light evenly in all directions, making them a popular choice for general illumination.

They are widely used in high bay lighting warehouse setups where open areas need consistent brightness without dark spots.

Best Applications

UFO fixtures shine in open, undivided spaces. Common uses include:

• Open floor warehouses and distribution centers
• Manufacturing and assembly floors
• Loading docks and receiving bays
• Gymnasiums, sports halls, and arenas
• Covered outdoor canopies and outdoor storage
• Large retail stores without defined aisle structures

Warehouse managers and industrial operators in facilities with open floor plans consistently report better results with UFO fixtures over linear in these zones.

LED Linear High Bay Lights Explained

LED linear high bay lights are built for spaces where layout matters. Instead of spreading light in all directions, they guide it along a specific path. This makes LED linear high bay a smart choice for warehouses with aisles, racks, and organized storage. You get better visibility exactly where work happens, not wasted light in empty areas.

If your goal is efficient warehouse LED lighting, especially in structured spaces, linear fixtures help reduce shadows and improve clarity. They work well as a high ceiling LED light solution where precision matters more than wide coverage.

Best Applications

High bay lighting warehouse setups with defined structure need linear fixtures. This includes:

• Warehouses with tall racking and narrow aisles
• Cold storage and freezer facilities
• Distribution centers with forklift-operated aisles
• Manufacturing and production line zones
• Big-box retail with long floor sections
• Facilities replacing T5 or T8 fluorescent strip lights

Electricians retrofitting commercial facilities often default to linear when replacing fluorescent strips because the mounting footprint is similar and the results are a direct upgrade.

Comparison Table

Light Distribution

UFO fixtures distribute light in a 360-degree circle from the center. You choose your beam angle: 60 degrees for tall, focused applications; 90 degrees for general use; 120 degrees for wider spread at lower heights.

Linear fixtures distribute along their length. Symmetric lenses fan out evenly on both sides. Asymmetric lenses push more light in one direction, which is specifically useful for wall or rack face illumination. This is a capability UFO cannot match without extra fixtures.

Ceiling Height Recommendations

• Under 18 ft: Low bay fixtures, not high bay
• 18 to 25 ft: Either works; UFO at 100 to 150W, linear at 90 to 130W
• 25 to 35 ft: UFO at 150 to 240W or linear at 240W; beam angle matters
• 35 ft and above: UFO at 240W+ with 60 degree beam recommended

Installation Method

Both types use hook, pendant, aircraft cable, or conduit mounting. UFO is faster to install in open bays because it is a single compact unit. Linear fixtures need to be positioned along aisles, which takes a little more planning but delivers a cleaner result in structured layouts.

For retrofits, UFO replaces HID round fixtures with minimal changes. Linear replaces T5/T8 fluorescent strips almost directly, making it an easier swap in those settings.

Energy Efficiency & Operating Cost Comparison

Both fixture types consume 50% to 75% less energy than traditional HID or fluorescent systems. The US Department of Energy reports LED technology can cut commercial lighting energy use by up to 75%.

The real difference in operating cost often comes down to controls. Adding a pir motion sensor high bay control lets fixtures dim automatically during low-traffic periods. Industry data shows smart controls provide about 44% additional savings on top of the LED baseline.

How to Choose Between UFO and Linear High Bay Lights

Answer these three questions and the decision becomes straightforward.

1. What does your floor layout look like?

Open, undivided space with no defined aisles? Choose UFO. Rows of racking, production lines, or defined aisles? Pick linear. Mixed space? Use both in the right zones.

2. How high is your ceiling?

Under 20 ft, reconsider whether you need a high bay at all. 20 to 30 ft, both types work. Above 30 ft, a UFO with a tighter beam angle is usually the stronger performer.

3. What are you replacing?

Replacing metal halide round fixtures? UFO is the direct upgrade. Replacing T5 or T8 fluorescent strips? Linear is the natural swap with minimal wiring changes.

Still unsure? Most warehouse LED lighting projects end up using both. UFO fixtures for open receiving and staging areas, linear fixtures above racking and picking aisles.

Accessories: PIR Motion Sensor

A pir motion sensor high bay is one of the smartest upgrades you can add to any high bay installation. PIR stands for passive infrared. The sensor detects movement and tells the fixture to dim or power up accordingly.

In warehouse LED lighting setups, this means aisles that are not in use dim automatically. Workers or forklifts trigger full brightness on entry. No manual switching needed.

Benefits of adding a PIR sensor to your high bay:

• Additional energy savings beyond LED baseline
• Extends fixture lifespan by reducing full-power run time
• Works with both UFO high bay LED and LED linear high bay fixtures
• Compatible with 0 to 10V dimming drivers on most NBL products

For facilities running 16 or more hours per day, this accessory typically pays for itself within the first year.

FAQs

Can I use a UFO high bay LED in a space with tall racking?

You can, but the results in the aisle will not be ideal. LED UFO high bay fixtures are not designed to push light sideways onto rack faces. For aisles with tall racking, LED linear high bay is the better choice.

What wattage do I need for a 30-foot ceiling?

At 30 feet, a 150W to 240W UFO or a 200W to 310W linear will typically hit the 20 to 30 foot-candle target for general warehouse storage. For picking aisles requiring 30 to 50 fc, go to the higher end of that range.

Are Nothing But LEDs products DLC listed?

Yes. Most NBL high bay products carry DLC Standard or DLC Premium certification. This qualifies them for utility rebate programs in most US states. Check the specific product page for confirmation.

Does high bay lighting warehouse require a special voltage supply?

Most NBL products run on standard 120 to 277VAC. Some industrial models support 277 to 480VAC for facilities with higher voltage supply. Always check the product spec before ordering.

How many fixtures do I need?

Calculate: (Area in sq ft x Target foot-candles) divided by fixture lumens = approximate fixture count. For accuracy in large spaces, use a photometric layout. Contact the NBL team for help.

What is the benefit of a pir motion sensor high bay in a warehouse?

It dims fixtures automatically when areas are unoccupied and brings them back to full power when movement is detected. This saves 30% to 50% more energy on top of what LEDs already save, and it extends fixture life.

Final Thoughts

Choosing between high ceiling LED light options comes down to your space, not a brand preference. For the open floor choose UFO. For aisles and racking choose Linear. For mixed needs choose both.

Both fixture types save 50% to 75% in energy costs over legacy lighting. Add a pir motion sensor high bay and those savings go even further.
