A versatile, smartly designed high bay fixture

Dependable performance for expansive spaces

Keystone’s XFit High Bay LED fixtures are renowned for energy efficiency, light uniformity, and long life. They’re ideal for replacing HID and linear fluorescent high bay lights, ensuring comfortable and safe conditions to maximize productivity in applications including commercial and manufacturing facilities, gymnasiums, warehouse lighting fixtures, and retail aisles.

Keystone XFit Linear High Bays feature an architectural grade I-Beam design in which the driver channel is spaced away from the LEDs, allowing for better airflow and thermal management. This unique design contributes to a significantly longer lifespan and increased efficiency.

All of our Linear LED high bay lights are DLC Premium listed and eligible for rebates.

Easy installation, dependable operation

Our XFit Linear High Bay fixtures are simple and fast to install. The primary mounting method mimics that of legacy HID downlight style high bay fixtures, making them ideal for retrofits or new installations. Pendant mount kits and surface mount kits provide flexibility in mounting options for these fixtures.

Power and Color Selectable – Versatile Solutions

The XFit High Bay is now available with Keystone’s innovative Power Select and Color Select technologies. Power Select allows end-users to select among three field-adjustable lumen outputs – 135W, 175W, and 215W; Color Select provides two color temperature selections, 4000K and 5000K. Both are changed with a simple switch. These flexible tools provide significant SKU reduction and increase flexibility and convenience when installing in the field.

The latest generation of Keystone High Bays is also compatible with Keystone’s new Smart Port sensor hardware, which uses a simple, screw-in 3-pin plug to add Keystone controls.
