LED Barn Lighting

Frequently asked questions

• What's the best LED light for a pole barn?

  For a typical 30×40 ft pole barn with 12–16 ft ceilings, 100W UFO LED high bay fixtures arranged in a 2×2 grid (4 total) produce 56,000 combined lumens — enough for excellent visibility across the entire floor at 30+ footcandles, well-suited for workshop tasks, vehicle parking and storage. For a larger 40×80 ft pole barn, scale to 8 × 100W or 6 × 150W fixtures.

• Are GGJIA LED lights safe to use in a livestock barn?

  Yes. All fixtures are IP65-rated for the dust and humidity in livestock environments, flicker-free (important for animal welfare), and operate without heat output that could ignite hay or feed. For livestock barns, use 4000K neutral white rather than 5000K daylight — bright cool light can disturb sleep cycles in dairy cows and horses.

• Can LED barn lights handle cold winter temperatures?

  Yes. All GGJIA commercial LED fixtures are rated for ambient temperatures from −22°F to 122°F (−30°C to 50°C). Residential LED fixtures are often only rated to 0°F and will shut down or flicker in cold unheated barns. Always verify the fixture's ambient temperature rating before purchase if your barn is unheated.

• How many LED lights do I need for a 40×60 barn?

  A 40×60 ft barn (2,400 sq ft) at 20 fc target with CU 0.5 and LLF 0.85: (2,400 × 20) ÷ (0.5 × 0.85) = 112,941 lumens. With 100W UFO fixtures (14,000 lm each): 8 fixtures in a 2×4 grid for 16-ft ceilings. With 150W fixtures: 6 fixtures. For higher pick-and-detail work (workshop, dairy parlor), use 30 fc target and scale to 10–12 fixtures.

• Can I install LED barn lights myself?

  For plug-and-cord installation in a barn with existing receptacles, yes — GGJIA high bays ship with a 6-ft 3-prong U.S. plug, hang on a hook, plug into the outlet. For permanent hardwired installation, NEC requires a licensed electrician. Many homeowners install temporarily with the plug-cord and hire an electrician to convert to hardwired later.

• Do I need DLC certification for barn lighting rebates?

  Most utility rebate programs don't cover residential or agricultural installations (DLC programs are designed for commercial buildings). However, working agricultural barns operated by registered farms may qualify for USDA Rural Energy for America Program (REAP) grants or state agricultural utility programs. Check with your USDA Rural Development office for current programs in your state.

• What's the difference between commercial high bay and shop light for a barn?

  Commercial high bay (100W+, 14,000+ lumens) is rated for ceilings 12 ft and higher, with wider beam angle and higher light output. Shop lights (40W–60W, 4,000–8,000 lumens) are designed for ceilings under 12 ft with narrower beam coverage. For most pole barns at 14–16 ft, the 100W high bay is the better choice; for lower-ceiling sheds and small outbuildings under 12 ft, shop lights are appropriate.

• How do I light a horse arena?

  Riding arenas (60×120 ft minimum, often 80×200 ft for full-size) require uniform illumination at 20–30 footcandles with strict glare control to avoid spooking horses. Typical layout: 200W–400W UFO high bays mounted 20–30 ft high in two rows along the arena's long axis. For competition arenas, target 50 fc with 3:1 uniformity ratio.

• Are solar barn lights bright enough for actual use?

  For exterior security lighting and walkway illumination at remote barns: yes, 30W–60W solar LEDs producing 4,000–8,000 lumens are appropriate. For active workspace lighting (shop work, livestock check, riding arena), grid-tied LED is much brighter and more cost-effective per delivered lumen. Solar excels where utility power costs >$5,000 to extend to the barn.
