480-Volt LED High Bay Lights

What to Compare Before Ordering

• Input voltage: Confirm the fixture supports the actual circuit voltage.
• Delivered lumens: Compare light output, not wattage alone.
• Mounting height: Higher ceilings may need more lumens, tighter optics, or different spacing.
• Beam angle: Wide beams work in open areas; narrower beams may help on taller ceilings.
• Controls: Check 0-10V dimming, motion sensor, daylight harvesting, and emergency backup compatibility.
• Listing and environment: Review UL/ETL listing, DLC status, IP rating, ambient temperature, and emergency-lighting requirements.

Replacement and Layout Guidance

Legacy HID wattage can help estimate the starting point, but it should not be the final selection method. A fixture replacing a 400W, 750W, or 1000W metal halide must be compared by delivered lumens, optical distribution, mounting height, spacing, target foot-candles, and fixture condition. Some projects need fewer high-output fixtures; others need more lower-output fixtures for better uniformity.

For warehouses and production spaces, a photometric layout is the cleanest way to confirm quantity, spacing, and light levels. It also helps avoid over-lighting, glare, dark aisles, and fixture counts based only on old wattage.

Voltage, Mounting, and Emergency Options

High-voltage lighting can reduce amperage on a circuit. Amps are calculated by dividing watts by volts, so the same wattage draws less current on 480V than it would on 120V. That is one reason large facilities may use 347V or 480V lighting circuits, especially where long runs and large electrical loads are part of the building design.

Mounting choices include hook mounts, pendant mounts, surface mounts, trunnion or U-bracket mounts, and suspended cable options for linear fixtures. The mount affects aiming, service access, vibration, and how well the fixture fits the ceiling structure. For high ceilings, beam angle and fixture spacing are just as important as the mount.

Emergency and control options should be reviewed early. Some projects require battery backup capable of supporting emergency illumination for a defined period, often 90 minutes. Motion sensors, dimming, daylight controls, and backup accessories must match the fixture voltage, driver, and listing.

High Bay vs. Low Bay at 480V

High bay lights are used for higher ceilings, often above 20 feet, where concentrated output has to reach the floor or work surface. Low bay lights are used on lower ceilings and usually need a broader spread. Both can exist in high-voltage buildings, but ceiling height and layout determine the fixture type.

For high-ceiling 480V projects, compare the vertical and horizontal coverage together. The goal is enough light on shelves, equipment, walkways, and work areas without creating harsh bright spots directly under each fixture.

Choose 480 Volt LED High Bay Lighting

Match the fixture to the electrical service first. Then compare lumen output, mounting height, beam angle, controls, listing, and emergency requirements. LED Light Expert can help review voltage, layout, and fixture options before the project is ordered.

Why 480 Volt, and What It Changes

Many industrial and commercial buildings are wired for 480 volt three-phase service, and where that is the case the lighting should run on it. The reason is current: at higher voltage the same power draws less current, which permits smaller conductors, longer runs without voltage drop, and more fixtures on a circuit. On a large warehouse with long runs from the panel to the far end of the building, that is a real reduction in installed cost.

The requirement is that the fixture accepts the voltage. Many commercial LED high bays are built for a 120-277V range and will not run on 480V; a 480V fixture, or one with a universal 120-480V driver, is a different order code. This is the single most common ordering error on this category, and it is discovered on site rather than on paper.

Beyond voltage, the advantages are the ones that apply to any quality LED high bay. Service life runs up to 100,000 hours, which on a 30-foot ceiling means the fixture will likely outlast the tenancy. High colour rendering with a strong R9 value renders reds and skin tones accurately, which matters in any facility where people are inspecting product or reading colour-coded markings. And output can be matched to the task rather than to whatever the previous fixture happened to be.

Replacing HID with 480V LED High Bays

When you are converting metal halide or high-pressure sodium high bays, the interchange is settled by lumens rather than watts. The working conversions:

• Replacing a 250 to 320 watt HPS or metal halide fixture: use a 13,000 lumen LED at around 100 watts.
• Replacing a 400 watt metal halide or HPS: use a 150 watt LED high bay at about 20,000 lumens.
• Replacing a 750 watt metal halide or HPS: use a 32,000 lumen fixture at around 240 watts.

Mounting method is the other decision. A simple mounting hook is the fastest installation where the structure allows it and the fixture is being hung from existing steel or chain. Pendant, surface, and yoke mounts apply where the fixture must be fixed rather than hung, or where aiming is needed.

Confirm the ceiling height before selecting the lumen package, because it drives everything. The same square footage under a 20-foot ceiling and a 40-foot ceiling needs different wattages and different beam angles to land the same foot-candles on the floor, and no amount of extra output fixes a beam angle that is wrong for the height.

Buy 480 Volt LED High Bay Lights

High bays go in by the dozen rather than singly, so quantity pricing matters more on this category than most. DLC listing is worth checking as well, since many utility programs pay a per-fixture rebate on DLC-listed high bays and the fixture count makes that material.

What comes with every order:

• Free shipping on orders over $49.00.
• Up to a 7-year warranty on LED lights. The exact term varies by series, so confirm it on the product page.
• Wholesale and contractor pricing for electricians and contractors buying in volume: wholesale LED lights.
• Net-30 terms and purchase orders for qualifying commercial, school, and municipal accounts: net-30 and PO terms.
• A free photometric study before you order, so fixture count and placement are confirmed rather than estimated: free light study.

To quote, confirm the service voltage first - 480V, 277V, or 120-277V - then send the ceiling height, approximate square footage, the fixture count, and the wattage being replaced. Getting the voltage stated up front avoids the most expensive mistake on this category.
