Easily upgrade HID lights to energy efficient UFO LED high bay fixtures

Menu

Designed for safe, reliable performance

Keystone’s XFit Round LED High Bay fixtures, also called UFO LED high bays, are ideal for replacing or retrofitting legacy HID high bay lights, offering high performance and long life.

Typical applications include commercial and manufacturing facilities, gymnasiums, warehouse lighting fixtures, and retail aisles.

Keystone also offers high temperature-rated UFO LED high bay fixtures featuring an ambient operating temperature of 50°C/122°F. These are ideal for applications such as warehouses and manufacturing facilities in southern climates, and industrial buildings that have demanding temperature requirements.

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

Easy installation, dependable operation

Our XFit Round 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 – Flexible Solutions

Power and Color Select Logos

Our newest generation of round high bays feature Keystone’s innovative Power Select and Color Select technologies. Power Select allows end-users to select among three field-adjustable lumen outputs; Color Select provides three color temperature selections. Both are changed with a simple switch. These flexible tools provide significant SKU reduction and increase flexibility and convenience 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 — the easiest way to add motion sensing to your high bay solution.

Dedicated Options

Keystone XFit Round High Bays are also available in dedicated versions of 100W, 150W, and 200W, with color temperatures of either 4000K or 5000K. Accessories include UFO LED microwave sensors, which are easy to install and wire using an included quick connector.
