What types of facilities specify a 200W UFO high bay at 26,000 lumens?
This output class is commonly specified for warehouses, distribution aisles, manufacturing bays, and large-format retail where mounting heights and spacing require a higher delivered lumen package per fixture. The UFO form factor supports open-area coverage and is often used where fixtures are laid out in regular grids over work zones or racking.
What mounting height range is appropriate for a 110° beam high bay?
A 110° distribution is typically paired with mid-to-high mounting heights. Final mounting height and spacing should be validated with a photometric layout, but this optic is generally selected to balance horizontal illuminance with uniformity in open areas and standard warehouse grids.
How does the 110° beam angle affect fixture spacing and uniformity?
A 110° optic spreads light wide enough to support practical spacing while still maintaining center intensity for task areas below. Compared with very wide optics, it can reduce spill beyond the target zone; compared with narrow optics, it helps avoid high-contrast hot spots between fixtures when used in grid layouts.
What does the 5000K CCT indicate for visual conditions on the floor?
5000K is often specified in industrial and logistics environments where high visual contrast supports label reading, aisle identification, and general task visibility. It is commonly chosen for facilities that want a neutral-to-daylight appearance across large areas.
What does CRI 80 mean for warehouse and industrial tasks?
CRI 80 supports accurate enough color recognition for most industrial and commercial workflows such as safety marking recognition, packaging identification, and general task work. If an application requires higher color fidelity, confirm project requirements and review photometric/IES documentation for any additional color metrics provided.
What dimming method is supported, and what does 1–10V mean in practice?
This fixture is listed as 1–10V dimmable. In controls design, that typically means it can be integrated with compatible low-voltage control wiring and commercial dimming devices used for high bay applications. For commissioning, confirm minimum dim level behavior and any control polarity requirements in the manufacturer documentation.
Is this fixture compatible with occupancy sensors or daylight controls?
With low-voltage dimming, this type of high bay is commonly paired with standalone occupancy sensors, aisle sensors, or control panels that provide a dimming signal. For a project, verify that the selected sensor/control output is compatible with the fixture’s dimming input and that the control strategy meets local energy code requirements.
What does IP65 mean for dust and water exposure?
IP65 indicates the housing is dust-tight and protected against water jets. This rating supports use in industrial spaces with airborne dust and in covered exterior or semi-exposed areas where wind-driven moisture or washdown-adjacent conditions may occur, subject to site-specific placement and installation method.
How does the wet-location rating change where it can be installed?
A wet-location rating supports installation in areas exposed to direct moisture, including some covered outdoor work areas, canopies, and transitional zones where wind-driven rain or dripping water can occur. Installation still needs to follow the manufacturer’s instructions for sealing, conduit entry, and mounting to maintain the rating.
What role does integrated surge protection play in real installations?
Integrated surge protection helps reduce driver and LED-array exposure to transient voltage events that can occur from switching loads, storms, or utility disturbances. For sites with higher exposure risk, confirm the surge protection specification (kV rating) and coordinate with upstream protection and grounding practices.
Does DLC Premium matter if the project is pursuing rebates?
DLC Premium listing is frequently used by utilities to qualify fixtures for rebate programs and to document performance characteristics. For rebate submissions, confirm that the exact model and configuration being installed appears on the DLC Qualified Products List under the correct listing category.
What does the -40°F minimum operating temperature support?
-40°F operation supports cold-climate use and unconditioned spaces where fixtures may start at very low ambient temperatures, including refrigerated-adjacent areas, outdoor canopies in winter climates, and high-bay spaces that are not heated continuously.
What should be expected from a 50,000-hour rated life in a high-bay environment?
A 50,000-hour rating is typically used to estimate maintenance cycles and lumen maintenance expectations under defined test conditions. Actual service life depends on ambient temperature, operating hours, control strategy (dimming), and installation conditions that affect thermal management.
What should be verified for electrical service on 120–277V input?
120–277V input covers common commercial branch circuits, including 120V, 208V, 240V, and 277V systems. For installation, confirm circuit voltage, grounding method, conductor sizing, and any local code requirements for the fixture location and mounting hardware.
