Our T5 High Bay LED Replacement Lights for Fluorescent Fixtures include LED high bays for replacing 6-lamp T5 fluorescent fixtures, also identified as F54T5HO or F54/T5/HO fixtures. Available replacement lights range from 100 to 200 watts and produce 15,000 to 30,000 lumens. Color temperature options include 4000K and 5000K, with standard 100-277V and high-voltage 277-480V models. Product configurations include color-changing, wattage-changing, and beam-angle-adjustable high bays. Pendant and chain mounting options are also available.
Common applications for these LED high bay replacement lights include warehouses, gymnasiums, retail stores, and other commercial spaces currently using 6-lamp T5 high bay fluorescent fixtures. A 150-watt LED high bay fixture can replace a 6-tube, 54-watt HO high bay that consumes 372 watts including ballast draw. These LED fixtures support one-for-one replacement of existing 6-tube F54T5HO fixtures. Available wattages, lumen outputs, voltage ranges, color temperatures, adjustable configurations, and mounting styles accommodate different existing high bay installations and commercial lighting layouts.
Replacing T5 Fluorescent High Bays with LED
T5 high bay LED replacement lights are used to replace older 4-foot fluorescent fixtures commonly found in warehouses, shops, factories, gymnasiums, and production areas. Most fluorescent high bays use 54-watt T5HO tubes, with each new lamp producing approximately 5,000 lumens. The actual light reaching the floor is lower after accounting for the fixture reflector, ballast, lamp age, dirt, and light trapped inside the housing.
Linear LED high bays are usually the closest replacement because their rectangular shape and broad distribution resemble the original fluorescent fixture. A UFO LED high bay can also be used when its lumen output, optics, mounting height, and spacing provide the required coverage. UFO fixtures are often a good option in open areas, while linear fixtures may provide better coverage over aisles, rows, and rectangular workspaces.
LED Lumens for Common T5 High Bay Replacements
| Existing T5HO Fixture | Approx. Fluorescent Lamp Lumens | Suggested LED Fixture Range |
|---|---|---|
| 2-Lamp T5HO | Approx. 10,000 lumens | 8,000-12,000 LED lumens |
| 4-Lamp T5HO | Approx. 20,000 lumens | 15,000-22,000 LED lumens |
| 6-Lamp T5HO | Approx. 30,000 lumens | 22,000-30,000 LED lumens |
| 8-Lamp T5HO | Approx. 40,000 lumens | 30,000-40,000 LED lumens |
| 12-Lamp T5HO | Approx. 60,000 lumens | 40,000-55,000 LED lumens |
These ranges are practical starting points, not guaranteed one-for-one replacements. A lower-output LED may equal or outperform a higher-lumen fluorescent fixture because LED high bays direct more light toward the work area. However, replacing a linear fluorescent fixture with a compact UFO may change fixture spacing and light distribution even when the lumen output is similar.
Before ordering, confirm the existing lamp count, mounting height, fixture spacing, voltage, aisle or open-area layout, and required foot-candle level. For larger facilities or projects where uniformity and task lighting are important, use a photometric lighting plan to verify fixture quantity, output, spacing, and optics.
Certifications and Warranty
Confirm the selected LED high bay carries a recognized safety certification such as UL, ETL, or CSA and verify DLC or DLC Premium status when utility rebates are expected. Product voltage, dimming, controls, environmental ratings, and warranty coverage vary by model. Most LED Lighting Supply high bays include a 5-year warranty unless otherwise specified.
T5 High Bay LED Replacement Lights FAQs
How Do I Choose Between Linear And UFO LED High Bays For A T5 Replacement?
Choose linear LED high bays when replacing fixtures over aisles, rows, or rectangular workspaces, and consider UFO high bays for open areas. The final choice should also account for lumen output, optics, mounting height, spacing, and required coverage.
Can I Match A T5 High Bay With The Same LED Lumen Output?
No, matching fluorescent lamp lumens one-for-one is not always necessary or appropriate. LED high bays can direct more light toward the work area, while a change from a linear fixture to a compact UFO can alter spacing and light distribution even at similar lumen output.
What Should I Confirm Before Ordering LED T5 High Bay Replacements?
Confirm the existing lamp count, mounting height, fixture spacing, voltage, layout, and required foot-candle level before selecting a replacement. Also verify model-specific dimming, controls, environmental ratings, warranty coverage, and applicable safety certifications.
When Is A Photometric Lighting Plan Useful For A T5 High Bay Upgrade?
A photometric lighting plan is especially useful for larger facilities or projects where uniformity and task lighting are important. It can verify fixture quantity, output, spacing, and optics for the planned layout.
What Certifications Should LED T5 High Bay Replacements Have?
Select an LED high bay with a recognized safety certification such as UL, ETL, or CSA. When utility rebates are expected, verify whether the specific model has DLC or DLC Premium status.
