High Lumen High Bay

Optics & Beam Angle Options

Lumen Output by Wattage

157,000-Hour L70 Rating

L70 is the industry-standard lifespan metric — the point at which a fixture's output has declined to 70% of initial rated lumens. This fixture is rated to L70 at 157,000 hours at 77°F ambient. At 16 operating hours per day, that is approximately 26 years before reaching L70. Budget-tier UFO high bays commonly publish 50,000-hour L70 ratings — roughly 8.5 years under the same conditions. In facilities where high-bay replacement requires aerial lift access, fewer replacement cycles represent real and quantifiable maintenance cost savings.

Recommended optic: AC22 or PC22

Larger lens diameter widens the spread for mid-range ceilings.

157,000-hour L70 vs. 50,000 hours in budget alternatives

Many comparable UFO high bays on the market publish 50,000-hour L70 ratings — roughly 8.5 years at 16 hours per day. This fixture is rated to 157,000 hours, approximately 26 years. In a facility where replacing high-bay fixtures requires a scissor lift or aerial work platform, the difference between zero relamping cycles and two or three over a building's life is a real, quantifiable maintenance cost.

Up to 173 lm/W vs. 145 lm/W in comparable fixtures

At up to 173 lm/W (100W model), this fixture delivers measurably more light per watt than competing options rated at 145 lm/W. On a 100-fixture installation running 16 hours per day at $0.12/kWh, the 28 lm/W efficacy difference at 100W scale translates to approximately $5,250 per year in electricity savings compared to a 145 lm/W alternative.

10-year warranty option

The standard 5-year replacement warranty is upgradeable to 10 years at time of order — roughly double the industry-standard coverage term for UFO-style high bays. Coverage is full fixture replacement with no prorated depreciation.

Both voltage ranges in one product family

The standard L variant covers 120–277V; the UH variant covers 277–480V for three-phase industrial distribution. Both use identical optics, reflectors, and mounting hardware — one product family covers your entire facility regardless of service voltage.

IES photometric files included

Downloadable IES photometric files are available for multiple wattage configurations. IES files allow lighting designers and engineers to model photometric performance in AGi32, DIALux, or REVIT before installation — verifying footcandle levels, spacing, and uniformity on paper before a single fixture is ordered. Most competing products at this price point do not provide IES files.

What ceiling height range is this fixture designed for?

High lumen high bay fixtures perform best in spaces with ceiling heights between 20 and 50 feet. At 20–25 ft, the 100W model with a 120° optic typically achieves the 30–50 footcandles recommended for general warehouse tasks. At 35–50 ft, the 200W or 240W model paired with a 70° AL-series reflector maintains adequate light levels at floor height.

What does the 157,000-hour L70 rating mean in practice?

L70 is the point at which a fixture's lumen output has fallen to 70% of its original rated value. At 157,000 hours, running 16 hours per day, you reach L70 after approximately 26 years. Most budget-tier UFO high bays are rated to 50,000 hours L70 — roughly 8.5 years under the same conditions. In tall facilities where aerial lift access is required for replacements, the difference between zero relamping cycles and two or three over a building's life is a meaningful cost factor.

What does the warranty cover?

The standard 5-year warranty covers full fixture replacement — if a fixture fails within the warranty period, a replacement unit is shipped out with no prorated depreciation. A 10-year warranty upgrade is available at time of order. Contact us for complete terms.

Is the 277–480V version a separate product?

Yes — the UH (ultra-high voltage) variant uses a different driver housing and is slightly larger and heavier. It accepts the same optics, reflectors, and mounting accessories as the standard L version. Specify the UH suffix when ordering for 277–480V applications.

Does dimming require a separate accessory?

No. A 12-inch 0–10V dimming cord ships standard with every fixture. You will need a compatible 0–10V dimming controller or building automation interface on the electrical side, but no additional fixture hardware is required.

What certifications qualify this fixture for utility rebates?

The DLC Premium listing is the primary rebate qualification. DLC Premium is the highest DesignLights Consortium tier and unlocks rebate eligibility in virtually all U.S. utility programs that recognize DLC-qualified products. ETL Listing separately satisfies building code safety compliance in most jurisdictions.

Does Averlite offer free lighting plans?

Yes. Submit your floor plan dimensions, ceiling height, and target footcandle levels and our team will produce a complete photometric layout — fixture placement, spacing, footcandle heat maps, and fixture count. Contact us to get started.
