LED Linear High Bays

What are LED Linear High Bays?

Linear high bay lights are panel-style indoor LED High Bay Lights that replace F54/T5/HO or T8 fluorescent systems in high ceiling applications. These rectangular fixtures use LED strips on the back panel to deliver uniform light distribution throughout large spaces. They are a common form of LED warehouse lights used in commercial warehouses today.

Wire or chain mounting provides secure installation, though pendant and surface mount options are available for specific layouts. Wide light distribution creates even coverage without hot spots or dark areas.

We offer these fixtures in 100-277V standard voltage and 277-480V high voltage configurations, plus color-adjustable and wattage-adjustable models for flexibility.

The customer had fluorescent high bays and got tired of the poor light quality. We converted the fixtures over one-for-one to LED Linear High Bays and made the lighting brighter and more balanced.

LED Linear High Bay Benefits vs Fluorescent Fixtures

Linear high bay LED lights offer key advantages over fluorescent systems in energy use, maintenance, and performance:

• Significant energy savings: Expect 50% or greater energy cost reduction compared to fluorescent linear lighting. Motion sensors can boost savings to 70-80% in intermittently occupied spaces.
• Superior light quality: High CRI 70+ LED technology maintains consistent brightness and color rendering throughout its 50,000+ hour lifespan.
• Eliminated maintenance: No bulb replacements, no ballast failures, and no flickering end-of-life issues found in fluorescent systems.
• Silent operation: LED drivers operate silently, unlike fluorescent ballasts that can hum over time.
• Instant illumination: Full brightness immediately upon startup, even in cold environments where fluorescents struggle.
• Motion sensor compatibility: Rapid on/off cycling and smooth dimming work with occupancy controls without special ballasts.
• Standard dimming capability: Most models include 0-10V dimming to save energy during low-activity periods.
• No hazardous materials: LEDs contain no mercury, eliminating the need for special disposal and environmental concerns.
• Easy installation: Direct wire connection with line, neutral, and ground, with no ballast wiring complexity.

* The U.S. Department of Energy's commercial lighting studies demonstrate that LED technology consistently outperforms fluorescent systems in industrial applications. According to DOE's LED lighting guidance, LED fixtures can reduce energy consumption by 50% or more when replacing traditional fluorescent high bay systems in warehouse and manufacturing environments.

What are the Cost Savings and ROI When You Convert from Metal Halide to LED?

165W LED Linear High Bay vs 400W Metal Halide Replacement (with ballast)

Assumptions: Based on 24 hours/day, 200 days/year at $0.20/kWh, 50 fixture(s), and a 15% ballast factor applied to the metal halide wattage (400W lamp + 15% ballast = ~ 460W input).
•  Energy cost and ROI calculations are based on energy savings only and assume an LED fixture cost of $155.00 per fixture.
• Maintenance savings from reduced bulb and ballast replacements are not included in these calculations.

In this example with 50 fixture(s), total LED fixture investment is approximately $7,750.00, and estimated annual energy-only savings are $14,160.00. Simple payback based on energy savings alone is under 7 months. Maintenance savings from eliminating metal halide bulb and ballast replacements provide additional value throughout the fixture's 50,000-hour lifespan, but are not included in this ROI calculation.

LED Replacement Guide for Fluorescent Systems

Replacing F54/T5/HO fluorescent fixtures with LED high bay lights follows straightforward one-for-one replacement ratios. The LED lumens needed depend on mounting height and specific application requirements (model dependent).

We typically recommend these replacement levels:

• 4 tube F54/T5/HO: 12,000 to 18,000 LED lumens
• 6 tube F54/T5/HO: 18,000 to 24,000 LED lumens
• 8 tube F54/T5/HO: 24,000 to 40,000 LED lumens

Installation mirrors existing fluorescent mounting - pendant, chain, or wire cable suspension connects to the same mounting options. Three-wire connection (line, neutral, ground) eliminates ballast complexity and reduces installation time.

Common Mistakes and How to Avoid Them

After thousands of fluorescent-to-LED conversions, the same installation errors keep showing up on job sites. Most stem from treating linear high bays like other fixture types instead of understanding their specific limitations and requirements.

• Installing linear high bays above 30 feet, where their wide distribution pattern becomes ineffective. Use UFO high bays with narrow beam optics for mounting heights over 30 feet.
• Specifying dry-location fixtures for food processing or wash-down areas. Linear high bays lack IP ratings and fail quickly in wet environments that require IP65 or higher protection.
• Sizing replacements based on fluorescent tube count instead of actual lumen requirements. See the replacement guide section above for proper lumen recommendations by tube count.
• Wiring motion sensor fixtures without connecting the dimming leads properly. The sensors control the dimming function, not just on/off switching like standard occupancy sensors.
• Using standard 120-277V fixtures on 480V industrial systems without checking driver compatibility. This creates immediate failure and potential safety hazards during startup.
• Mounting fixtures to the existing chain or cable without verifying the weight capacity. LED linear high bays often weigh 15-20 pounds more than the fluorescent fixtures they replace.
• Installing emergency backup fixtures without confirming they meet local fire marshal requirements. Some jurisdictions require specific lumen levels or battery backup durations that vary by application.

LED Linear High Bays Frequently Asked Questions

What are LED linear high bays used for?

LED linear high bays replace F54/T5/HO fluorescent systems in warehouses, manufacturing plants, gyms, and retail spaces with 15-30 foot ceilings. Wide light distribution provides uniform coverage without hot spots or dark areas in dry indoor locations.

How do I choose the right lumen output for my space?

Match LED lumens to your existing fluorescent tube count: 4-tube systems need 12,000-18,000 lumens, 6-tube systems need 18,000-24,000 lumens, and 8-tube systems need 24,000-40,000 lumens. Verify final selection with a photometric plan since mounting height affects actual lumen requirements.

What voltage options are available?

100-277V standard voltage works for most commercial applications, while 277-480V high voltage models integrate with industrial electrical systems. Confirm driver compatibility before installation since standard fixtures cause immediate failure on 480V systems.
