Industrial Keystone High Bay Lighting Solutions

Industrial environments demand lighting that is durable, efficient, and adaptable. Keystone high bay fixtures are engineered to meet these challenges head-on. Whether replacing 400W metal halides or T5HO fluorescent tubes, Keystone’s XFit series delivers superior brightness while slashing energy costs by up to 60%. The full lineup of Keystone round and linear high bays ensures the right form factor for every ceiling height and floor plan.

Keystone XFit High Bay: Round UFO Performance

For open floor plans like gymnasiums, manufacturing plants, and big-box retail stores, the Keystone XFit high bay (often called a "UFO") is the industry standard.

  • Rugged Design: Built with a die-cast aluminum housing and IP65 rating, these fixtures are dust-tight and water-resistant, making them ideal for harsh environments.
  • Thermal Management: The unique radial heat sink design keeps the LEDs cool, ensuring a lifespan of over 100,000 hours.
  • Easy Installation: Each unit comes with a pre-installed hanging ring for quick suspension mounting, drastically reducing labor time on large projects.

Linear High Bay LED Fixtures for Aisles

When lighting warehouse aisles or racking systems, light distribution is key. Keystone linear high bay LED fixtures feature a rectangular "I-beam" design that aligns perfectly with aisles to maximize visibility on vertical shelves.

  • Optimized Optics: Unlike round fixtures that spread light in a circle, linear high bays direct light along the length of the aisle, reducing wasted light on the tops of racks.
  • Architectural Appeal: The sleek, modern look makes them a favorite for retail spaces and open-ceiling offices.
  • Versatile Mounting: These fixtures can be suspended via V-hooks and chains (included) or surface-mounted for lower clearance applications.

Advanced Technology in Keystone High Bay Fixtures

Keystone distinguishes itself with features that simplify inventory and installation:

  • PowerSelect & ColorSelect: Most Keystone high bay models feature on-board switches to adjust wattage (brightness) and color temperature (3000K, 4000K, 5000K) in the field. One fixture can adapt to multiple ceiling heights and client preferences.
  • SmartLoop Ready: Integrated SmartPort sockets allow you to screw in a motion sensor or a Bluetooth mesh controller in seconds. This upgrades a standard fixture to a smart, networked system without any complex wiring.

Frequently Asked Questions

Do Keystone high bay fixtures come with a warranty?

Yes, Keystone XFit high bay fixtures are typically backed by a 5-year manufacturer warranty, covering the driver and LED chips. Some premium performance models may carry a 10-year warranty. For specific terms and coverage details, please refer to the Keystone Complete Statement of Warranty.

What is the difference between Keystone Round (UFO) and Linear High Bays?

Round UFO high bays cast a circular beam, making them ideal for open areas like gyms and general warehousing. Linear high bays cast a rectangular beam, which is better for illuminating long, narrow spaces like warehouse aisles and racking systems.

Are Keystone XFit high bays dimmable?

Yes, standard Keystone XFit high bays come with 0-10V dimming drivers. This allows them to be connected to standard wall dimmers or commercial control systems for energy savings.

What mounting options are included with Keystone high bays?

Round UFO high bays typically include a hanging ring (eye bolt) for suspension. Linear high bays usually come with V-hooks and chains. Surface mount kits and pendant mount kits are often available as separate accessories.

Can I add motion sensors to Keystone high bays?

Yes. Many Keystone high bays feature a SmartPort sensor receptacle. You can simply screw in a compatible PIR or microwave sensor to add occupancy sensing or daylight harvesting capabilities without extra wiring.

What is the benefit of PowerSelect technology?

PowerSelect allows you to adjust the fixture's wattage on-site. For example, a 200W fixture can be switched to 150W or 100W. This lets you match the brightness to the ceiling height or task requirements without buying different fixtures.

Are Keystone high bays suitable for wet locations?

Keystone Round (UFO) high bays are generally IP65 rated, making them suitable for wet and dusty locations. Linear high bays are typically rated for damp locations but may not be fully waterproof; always check the specific spec sheet.

How do I control Keystone high bays wirelessly?

You can use the SmartLoop system. By screwing a SmartLoop controller into the sensor port, the fixture becomes part of a Bluetooth mesh network that you can control, group, and schedule via a smartphone app.

What voltage do Keystone high bays run on?

Most XFit high bays are "universal voltage," operating on 120-277V. Keystone also offers dedicated high-voltage models (277-480V) for industrial facilities with 480V power systems.

Can I replace my metal halide fixtures with Keystone LEDs?

Absolutely. A Keystone LED high bay typically uses 50-60% less energy than a metal halide equivalent. For example, a 150W LED high bay can often replace a 400W metal halide fixture while providing better light quality and instant-on capability.
