Continuous-Shift Manufacturing & Industrial Plants

• The Contractor Challenge: Avoiding costly downtime and maintenance in non-conditioned industrial settings subjected to severe vibration and continuous thermal stress.

• Our Solution: UL Listed for Damp Locations, this line utilizes specialized thermal venting to function continuously in ambient temperatures ranging from -4°F to 131°F (-20°C to 40°C). The fully isolated, spark-free driver ensures instant-on performance without any warming cycles.

Strict Technical Compliance: UL Listed & DLC V6.0 Premium

Meeting local building codes and capturing massive utility financial incentives requires certified engineering metrics. Every 4 foot high bay led lights model is third-party certified to guarantee uncompromised facility safety and efficiency.

UL Listed for Demanding Environments

Certified under strict safety standards, our fixtures maintain consistent performance under harsh commercial conditions. Robust steel end caps protect critical components under continuous, multi-shift operating cycles.

DLC V6.0 Premium Qualified Rebates

Operating reliably within the ultra-efficient 150-180 lm/W performance window, these linear luminaires are DLC V6.0 Premium qualified. This elite rating ensures electrical contractors, builders, and property managers qualify for maximum financial rebates from major North American utility incentive programs, bringing your project’s payback period down significantly.

High-Clarity LED Linear High Bay 5000K Daylight Optics

Visual accuracy is vital for workspace safety and operational velocity. Our 4FT led linear high bay 5000k fixtures provide clean, bright daylight color temperatures that completely wipe out glare and shadows in high-density storage facilities.

Advanced Light Distribution & High CRI

Engineered with an accurate color rendering rating of CRI >82, our systems project clean foot-candles directly where they are needed most. Standard options range across 3000K, 4000K, and 5000K configurations to suit various architectural project guidelines.

Contractor-First Engineering: Easy Installation & Advanced Controls

Minimizing field assembly time directly protects your project’s bottom line. The 4FT linear high bay platform features a highly accessible chassis built for prompt mounting and swift system additions.

• Tool-less Accessibility & Wiring: Designed with standard wiring knockouts on the back and ends, alongside integrated quick-disconnect terminal blocks, electrical contractors can complete wiring swiftly and easily without complex tools. It naturally accommodates stable suspended chain installations or tight surface mounted brackets.

• Plug-and-Play Easy Installation Sensors: Enhance automated energy conservation via optional plug-and-play PIR or microwave motion sensors. Featuring smooth 0-10V dimming, ambient daylight harvesting, and effortless wireless configuration up to a 50-foot mounting ceiling—complying with Title 24 or ASHRAE 90.1 guidelines has never been simpler.

• Code-Compliant Emergency Backup Systems: Maintain strict facility safety protocols with our reliable emergency battery backup kits (EM kits). Driving a dedicated 10W power loop for a guaranteed 1.5 hours (≥90 minutes) during blackouts, these emergency modules fully meet NEC and NBCC life-safety regulations.

🙋‍♂️ Frequently Asked Questions (FAQ) — Project Specifications & Procurement

Q1: With prices set directly at $40.00 for the 200W and $60.00 for the 300W models, how are these high-efficacy 4FT high bays so cost-effective?

• Answer: As a vertically integrated B2B lighting factory with dual-origin manufacturing operations, we eliminate the steep price premiums charged by North American corporate brand layers. Our automated 4FT assembly lines optimize material yields for heavy-duty steel housings and isolated Class II/P drivers, allowing us to pass real factory-floor savings directly to lighting companies, commercial builders, and stocking electrical distributors.

Q2: Why is a 4FT linear high bay preferred over 2FT variants for ultra-high warehouse or industrial ceilings?

• Answer: Ceiling heights above 30 or 35 feet require massive lumen outputs to hit correct floor-level foot-candle targets. While a compact 2FT model excels at mid-height retrofits, our 4FT footprints deliver up to 54,000 lumens. This longer form factor spreads the LEDs across a larger physical surface area, improving heat dissipation for the high-wattage drivers and offering an engineered wide angle (115 degrees) to cover massive commercial spaces evenly.

Q3: What makes your 300W selectable model an effective “T5 Killer” replacement for multi-lamp fluorescent fixtures?

• Answer: Legacy 6-lamp or 8-lamp T5HO fluorescent high bays consume extensive energy, decay rapidly in light output, and require expensive multi-lamp maintenance cycles. Our 300W 4FT linear model functions as a true replacement, outputting up to 54,000 lumens on a long-lasting solid-state platform. It cuts energy costs by over 50% instantly, completely removes re-lamping maintenance, and handles heavy-duty daily facility operational cycles seamlessly.

Q4: How easily can a field technician wire and install these 4FT linear high bays on a fast-paced project?

• Answer: We prioritize contractor speed. The 4FT chassis is built with tool-less entry access panels, a clean row of standard electrical knockouts on the back and ends, and quick-disconnect wiring blocks. Whether your crew is hanging the fixtures via suspended V-hooks and chains or installing them tight via surface-mounted brackets, wiring takes only minutes per fixture, minimizing field labor costs.

Q5: Can these fixtures handle harsh, unconditioned environments like loading docks or industrial storage spaces?

• Answer: Yes. Our 4FT platforms are officially UL Listed for Damp Locations and built inside a heavy-gauge rigid steel housing treated with a baked white enamel finish. They are certified to operate continuously in ambient environments from -4°F to 131°F (-20°C to 40°C), which means they resist moisture, dust, and temperature shifts common in unconditioned logistics centers and heavy industrial plants.

Q6: How do the optional smart motion sensors help project builders meet local building regulations?

• Answer: Many states and provinces throughout the US and Canada enforce strict energy guidelines (such as California’s Title 24 or ASHRAE 90.1) mandating automatic shut-off or bi-level dimming in unoccupied warehouse zones. Our 4FT fixtures feature an integrated port for plug-and-play PIR or microwave sensors. Once snapped on, they enable automatic step-dimming, occupancy tracking, and daylight harvesting, helping project builders pass compliance checks effortlessly.
