LED Linear High Bay Light Sensor Ready | 18K Lumens Max | CCT Selectable | HBLSR-181512L-4K5K

Engineered to deliver high-efficacy commercial and industrial lighting, the Linear Double Lens Sensor-Ready High Bay (Model HBLSR-181512L-4K5K) provides dynamic light distribution, long-term operational savings, and seamless Smart Control integration. Constructed with a heavy-duty, stamped steel housing and high-impact polycarbonate double lenses, this industrial high bay fixture resists physical impacts, vibration, and thermal stress. It is specifically designed as a high-performance LED retrofit or new-construction solution for high-ceiling environments, including commercial warehouses, distribution centers, manufacturing facilities, logistics hubs, gymnasiums, and big-box retail aisles.

Equipped with field-adjustable performance switches, this fixture features Tri-Lumen field selectability, allowing contractors to toggle between 12,000 lumens, 15,000 lumens, and 18,000 lumens from a single SKU. In addition, field-selectable color temperature controls enable seamless switching between 4000K neutral white (for balanced, comfortable task clarity) and 5000K cool white (for high-contrast, alert industrial environments). Powered by premium, patent-safe LED chips, the fixture operates at peak luminous efficacy, maintaining an exceptional L70 rated lifespan exceeding 134,000 hours (and L90 life of 40,000 hours) to eliminate ongoing maintenance costs and lamp replacements.

Designed for intelligent energy management, the fixture includes a integrated screw-in sensor socket that accepts plug-and-play occupancy sensors and daylight harvesting controls (sold separately). The fixture ships standard with a medium optical distribution lens, while optional narrow and wide distribution lenses are available to tailor beam angles for narrow warehouse aisles or open-area floor plans. Operating on universal line voltage (120-277V AC at 50-60Hz) with standard 0-10V continuous dimming drivers, this high bay maintains a high power factor (>0.90) and low total harmonic distortion (<20%). It is DLC 5.1 Premium listed, cULus damp location rated for extreme ambient temperatures ranging from -40°C to 55°C (-40°F to 131°F), features 6kV transient surge protection, complies with FCC Part 15 Class A standards, and includes a complete V-hook chain mounting kit backed by a 5-year warranty.

Key Features:

• Field-Selectable Lumen & CCT Versatility: Customize light levels on site with 3 lumen outputs (12,000 / 15,000 / 18,000 LM) and 2 color temperatures (4000K / 5000K) to streamline inventory and project requirements.

• Smart Control & Sensor Ready: Features a built-in screw-in sensor socket for quick twist-lock attachment of motion, PIR, or daylight harvesting sensors without opening the fixture housing.

• Commercial-Grade Durability: Heavy-duty stamped steel housing paired with glare-reducing, impact-resistant polycarbonate double lenses built to withstand industrial environments.

• High Efficiency & Utility Rebate Eligible: Qualified for DLC 5.1 Premium (medium distribution) to maximize utility energy efficiency rebates and lower total cost of ownership.

• Universal Voltage & Smooth Dimming: Operates reliably across universal 120-277V AC line inputs with 0-10V DC continuous dimming drivers for smooth lighting control.

• Extreme Temperature & Safety Certified: cULus listed for damp locations with an operating range of -40°C to 55°C (-40°F to 131°F) and 6kV surge suppression.
