Best Lighting for a Metal Building & Pole Barn
Metal buildings and pole barns bring their own lighting challenges: exposed purlins, tall open spans, reflective steel, and often a single power drop. The right fixtures and mounting plan deliver bright, even light without hot spots or shadows, and install cleanly to steel framing.
For metal buildings, the Bolt low bay and Stingray high bay mount easily to purlins and deliver uniform T8 coverage. Choose by clear height, and use our fixture calculator to set spacing across the span.
Why Metal Building Lighting Is Different
- Open framing. Fixtures hang from purlins or chains, so light weight and easy mounting matter.
- Reflective steel. Bright walls can cause glare; even distribution beats a few overpowered fixtures.
- Tall, open volume. Mounting height drives fixture choice and beam spread.
Traditional vs. Modern Metal Building Lighting
| Lighting Type | Lifespan | Maintenance | Efficiency | Best For |
|---|---|---|---|---|
| Metal Halide / HPS | 6k to 24k hrs | High, lift to relamp | Low to moderate | Old HID pole-barn lights |
| Fluorescent T8 / T12 | 15k to 20k hrs | Moderate | Moderate | Strip fluorescents |
| Integrated LED | 50k+ hrs | High, full fixture swap | High | Sealed integrated units |
| PrimeLights Patented T8 LED | 50k to 100k+ hrs | Lowest, ground-level tube swap | High, 150 to 200+ lm/W | Pole barns and steel shops |
PrimeLights fixtures stand apart because the driver lives inside the replaceable LED tube, not the fixture body. There are no external drivers or chip boards to fail. If a tube ever goes (rare with DLC-listed tubes), you spot it from the floor and swap it in minutes. No tools, no electrician, no lift, no downtime. That is why purlin-mounted T8 fixtures keep paying off long after a sealed integrated fixture would have you on a ladder. See why replaceable-tube fixtures beat integrated LED for facilities.
Choosing by Height
Under about 14 feet, the Bolt low bay spreads light evenly without overlighting. Above that, the Stingray high bay carries light to the floor. Our mounting height and beam angle guide explains how spread and spacing change with height, and the high bay vs low bay guide helps you pick.
Wet, Dusty, or Unconditioned Spaces
For damp or dusty pole barns, sealed vapor-tight fixtures last far longer. See our IP ratings guide.
Specs to Look For
- Chain, cord, or surface mount options for purlins
- Wide distribution for even floor coverage
- 4000K to 5000K
- High efficiency: 150 to 180+ lumens per watt
- DLC qualified so the project can capture utility rebates
- Instant-on with no flicker or warm-up
- 5+ year warranty
- Replaceable tubes for ground-level service
How to Choose
- Measure clear height to the purlin.
- Pick Bolt or Stingray accordingly.
- Lay out spacing with the calculator.
- Use vapor-tight in unconditioned or wet areas.
