Keystone XFit Round High Bay

Versatility, Energy Efficiency, and Safety

XFit Round High Bays feature Keystone's OpticSwap simple optic lens-changing technology, allowing users to optimize light to a space on site, eliminating special orders and simplifying installation. They're ideal for applications such as gymnasiums, warehouses, and retail, and with screw-in sensing options and a specially designed emergency backup option, they're optimized for energy efficiency and safety. That's Light Made Easy®.

The Right Light for the Space

OpticSwap, Keystone's revolutionary optics innovation, allows one fixture to be used across an entire project. The same fixture can be used to optimize light for various spaces by switching out optic lenses on site. All that's needed is to release some latches.

One Fixture is All That's Needed

 Using one fixture with one spec wastes light and costs more in energy. The flexibility of Keystone's fixture allows the user to put the right light in the right spot, whether open areas or narrow aisles. Installation is simple; ROI, immediate.

Power and Color Select

Select from among 3 power outputs and 3 color temperatures on Keystone's General Purpose Round High Bays and Round High Bays with OpticSwap. The switches are in a convenient location for easy adjustment, so the user can pick the brightness and CCT that meet their needs on site.

High-wattage Models

Keystone's 400W High Power Round High Bay is optimized for 40'-plus mounting heights and related higher ambient temperatures. They're capable of 58,000 lm and feature Power and Color Select, 0-10V dimming, and Keystone SmartPort sensor receptacle. TAA options are available.

Multiple Installation Styles

Keystone's UFO LED high bays are as easy to install as the legacy HID downlight-style high bays they replace. Both surface mount and pendant mount kits are offered, adding flexibility to installation options.

Emergency Backup by Design

Keystone's SmartSafe LED Emergency Backup Driver for Round High Bays is specifically designed for their round high bay - and with fixture, power supply, and backup from the same manufacturer, the user can trust they'll work together immediately, saving on evaluation and maintenance. It features a one-piece, 40W constant wattage design with self-diagnostics, and can be pre-installed at the factory to save on labor.

SmartPort Sensor Compatibility

Motion sensing turns the lights on only when someone is present, saving energy. And Keystone's simple, screw-in 3-pin plug is the easiest way to add motion sensing to a high bay solution: A twist of the wrist, and the lighting is ready to go.

Taking Control

Adding wireless control is as easy as screwing in a sensor. Keystone SmartLoop wireless lighting control, a Bluetooth mesh system, features a variety of components that are easy to install and commission, allowing the user to set up and manage their lighting ecosystem quickly. Use it for grouping, sensing, and scheduling.

Handling the Heat

Keystone knows that facilities like warehouses can get hot. That's why their high bays are rated for ambient temperatures to at least 122°F, with high-temp models able to handle 149°F. They feature a unique driver housing with heat sink fins added for greater heat dissipation. They're designed to handle harsh conditions. Keystone also offers the UFO LED high bay in 277-480V for high-voltage applications.

Built-in Keystone LED driver

Keystone drivers are 100% end-of-line tested, rugged, and reliable. They give the fixtures 0-10V dimming and ample surge protection for increased versatility and durability. And with fixture and driver from the same manufacturer, the user can count on compatibility.
