The Ascend LHB Series is a robust linear LED high bay lighting solution designed specifically for industrial environments such as warehouses, factories, workshops, and other large-scale applications. This series offers three different models, each tailored for maximum flexibility and performance with selectable Correlated Color Temperature (CCT) and wattage options. The 180W LO model delivers up to 24,000 lumens, the 290W HI model produces up to 42,000 lumens, and the powerful 450W MAX model provides up to 65,000 lumens. The CCT is field adjustable between 4000K, 4500K, and 5000K, allowing users to customize the lighting to suit their specific comfort and operational needs.
Constructed from low-copper content aluminum, the Ascend LHB Series features a durable white thermoset powder coat finish that enhances corrosion resistance and longevity. The fixture is equipped with stainless steel hardware made of marine-grade 316 stainless steel, ensuring strength and reliability in demanding environments. Its polycarbonate lens protects the LEDs while diffusing light evenly. With a rated life of 100,000 hours and an operating temperature range from -40°C to +55°C, the Ascend LHB Series guarantees long-lasting, consistent illumination and is backed by a five-year warranty for added peace of mind.
For enhanced safety and reliability, an optional Emergency Battery Backup (EMB) is available, capable of maintaining illumination during power outages for up to 90 minutes. Additionally, an optional occupancy sensor can be integrated to optimize energy savings by controlling light output based on space usage.
The Ascend LHB Series offers a broad range of wattage configurations to fit different space sizes and lighting requirements: the LO model includes 80W, 125W, and 180W options, the HI model offers 200W, 240W, and 290W, while the MAX model provides higher outputs at 325W, 385W, and 450W. Correspondingly, lumen outputs range up to 24,000 lumens for the LO model (available in a 2-foot length), 42,000 lumens for the HI model (also 2-foot length), and an impressive 65,000 lumens for the MAX model, which comes in a 4-foot length.
Power is supplied via standard AC voltages of 120-277V or 277-480V at 50-60Hz, and the fixtures are equipped with 0-10V dimming drivers for flexible light control. The power factor exceeds 0.9, and total harmonic distortion (THD) is maintained under 20%, supporting energy efficiency and reducing electrical noise. Surge protection is built-in with a 6kV rating in compliance with ANSI C62.41 standards, ensuring robustness against voltage spikes.
The Ascend LHB Series uses a diffuse polycarbonate lens combined with two optical options: the standard XF extra wide flood optic, which provides a 120° beam angle for broad coverage, and an optional AW aisleway optic with a 50° by 90° flood pattern designed to optimize lighting in narrow aisles or corridors. Mounting is versatile with included dual V-hook suspension mounts for easy installation, and additional aircraft cable or surface mount options are available to accommodate different ceiling types and heights.
The series meets rigorous certification and compliance standards including UL/cUL listing for damp locations (UL 1598), FCC Part 15 Class A, DLC v5.1 Premium, and RoHS, ensuring safety, quality, and energy efficiency. The fixture's dimensions vary by model, with the LO and HI models measuring 25.8 inches in length and the MAX model extending to 42.6 inches, all maintaining a consistent depth of 3.28 inches to fit well in industrial ceiling spaces.
Overall, the Ascend LHB Series combines high-performance LED technology, durable construction, and customizable features to provide a reliable, energy-efficient, and adaptable lighting solution ideal for demanding industrial settings.
