The Complete Guide to Bolt T8 LED Low Bay & Shop Lights

Updated June 2026 · PrimeLights

The Bolt is the go-to fixture for the spaces most people actually work in: garages, repair bays, pole barns, and shops with ceilings up to the mid-teens. This guide covers configurations, mounting, and where the Bolt shines.

What Makes the Bolt Different

Like the Stingray, the Bolt keeps the driver inside each tube. A failed tube is a two-minute swap from a step stool, not a fixture replacement.

PrimeLights fixtures stand apart because the driver lives inside the replaceable LED tube, not the fixture body. There are no external drivers or chip boards to fail. If a tube ever goes (rare with DLC-listed tubes), you spot it from the floor and swap it in minutes. No tools, no electrician, no lift, no downtime. That is why the Bolt's replaceable tubes keep paying off long after a sealed integrated fixture would have you on a ladder. See why replaceable-tube fixtures beat integrated LED for facilities.

Configurations and Mounting

• 2-lamp: garages and lighter shops
• 3-lamp: busy shops and repair bays
• Cord-and-plug: no hardwiring needed
• Motion-activated: hands-free light

The Bolt suits ceilings roughly 10 to 14 feet. Above that, step up to the Stingray high bay; see the high bay vs low bay guide.

Where the Bolt Fits

It is the default for the garage and workshop, auto repair shop, and metal building and pole barn. Lay it out with the fixture calculator.
