400W 4ft Linear High Bay LED Shop Lights, 2 Pack - Super Bright

Our review of these 400W 4ft linear high bay LED shop lights finds them best suited for large commercial spaces where raw output and energy savings matter most. The two-pack delivers a combined 120,000 lumens of 5000K daylight output, making the biggest reason to buy their exceptional brightness and high 150 lm/W efficacy. Installation is straightforward for a single person thanks to a slim, 11 lb fixture profile and ready-to-hang suspension chains, so a maintenance crew can upgrade workshop or warehouse lighting quickly.

Key Features

• Super bright output: The 400W fixture produces 60,000 lumens each, offering near-instant, high-visibility daylight suitable for large open areas.
• High efficacy: Rated at 150 lm/W, the lights deliver strong illumination while reducing energy use compared with older high bay technologies.
• Easy installation: Slim 4 ft profile and 11 lb weight allow a single person to hang and adjust height with the included suspension chain.
• 0-10V dimming: Seamless 10%-100% dimming compatibility with 0-10V controls lets facilities tailor light levels for tasks and energy savings.
• Durable construction: Aerospace-grade aluminum housing with ventilated design helps manage heat and preserves lumen output over time.
• Commercial ready: UL/CUL listing and long life expectancy make these fixtures appropriate for warehouses, workshops and gymnasiums.

Who It's For

These high bay lights are aimed at commercial and industrial users who need very bright, daylight-color illumination across large floorplates: warehouse operators, manufacturing floors, gymnasiums, and large workshops will benefit from the 60,000 lm output and high efficacy.

Owners of smaller retail spaces or low-ceiling rooms should look elsewhere for lower wattage or smaller fixtures, and buyers who need integrated sensors or dimmers should note those items are sold separately since the lights are compatible with external PIR sensors and 0-10V dimmers rather than including them out of the box.

Pros & Cons

Pros

• Exceptional brightness and 5000K daylight color deliver clear task lighting across large areas.
• High 150 lm/W efficiency helps cut energy usage compared with legacy high bay lamps.
• Lightweight 11 lb design and suspension chain enable fast, one-person installation.
• Robust thermal design and UL/CUL listing support long life in commercial settings.

Cons

• Includes no integrated dimmer or PIR sensor, so buyers must purchase compatible controls separately.
• At 400W each, the fixtures are overkill for small rooms or low-ceiling installations.

Our Verdict

These 400W 4 ft linear high bay LED fixtures are a strong option for large commercial spaces that require bright, daylight-colored illumination and reliable long-term performance. Their high efficacy and simple suspension installation make them good value where lumen output and energy savings are priorities, but buyers should budget for external dimming or sensor accessories if those features are needed.

Frequently Asked Questions

Are these compatible with motion sensors?
Yes, the fixtures are compatible with PIR sensors but sensors are sold separately; they also support auto-dimming when paired with compatible controls.

Can these be dimmed natively?
They support 0-10V dimming from 10% to 100%, but a separate 0-10V dimmer or control system is required.

Are they suitable for industrial ceilings?
Yes, UL/CUL listing and robust thermal design make them appropriate for warehouses, workshops and other industrial ceilings.
