Lens & Optics

The adjustable optical system provides interchangeable aisle and open-area optics on the job site without tools or rewiring. The built-in beam selection switch allows installers to instantly toggle between three distinct distributions:

• 60° Narrow Optic (Included): Concentrates beam distribution for narrow racking aisles, focused task areas, and elevated mounting heights.
• 90° Standard Optic (Included): Delivers balanced distribution for standard warehouse floors.
• 105° Wide Optic (Included): Delivers broad, uniform beam distribution for open warehouse floors, staging areas, and general open-ceiling commercial layouts.

Smart & Control Features

The H22XL/480 features an integrated low-voltage control receptacle supporting modular sensing and automated facility lighting control:

• 0–10V Continuous Dimming (Standard): Standard dimming control compatible with commercial 0–10V dimmers.
• Sensor Compatibility (Accessory): Accepts field-installable PIR and microwave occupancy sensors via the integrated expansion port without opening the internal driver compartment.
• Lightcloud Blue (Accessory): Compatible with Bluetooth mesh controllers for wireless group control, automated scheduling, and occupancy sensing.

Compatible plug-and-play sensors include the PIR40 and MVS50 series — sold separately. Field sensor adjustments can also be managed using an optional handheld wireless remote (catalog # MSR1, sold separately).

Electrical

Powered by a Class 1 constant current driver operating on 480V AC at 50/60Hz. Delivers high electrical efficiency with a Power Factor >0.90 and Total Harmonic Distortion (THD) <20%. Integrated 4kV + 6kV surge protection protects internal electronics against line-to-line and line-to-ground transient voltage spikes. Includes pre-wired 0–10V dimming leads. Factory-equipped with a 6-foot cord. RoHS compliant.

Construction

Housing & Thermal: Precision die-cast aluminum housing. The housing functions as a high-efficiency passive heatsink, dissipating heat away from LED arrays and internal driver circuits to preserve lumen maintenance across the 100,000-hour rated lifespan.

Lens & Optics: Features a durable polycarbonate lens with an IK10 impact rating.

Finish: Commercial finish in White formulated for high resistance against corrosion and surface wear in demanding industrial facilities.

Environmental Sealing: IP69K rated and UL Certified for wet locations, providing a sealed barrier resistant to high-pressure washdown, dust, and moisture ingress. Ambient operating temperature range: −40°F (−40°C) to 122°F (50°C).

Dimensions & Weight: 16.5" Dia × 6.19" H. Fixture weight: 8.64 lbs.

Installation & Mounting

Standard Hardware: Ships standard with a heavy-duty 3/4"-14 NPT hanging hook accessory for quick suspension installation.

Mounting Options: Compatible with rigid pendant mounting via the PM KIT (sold separately).

Wiring: Includes a factory-installed 6-foot cord for power input and 0–10V dimming leads.

Accessories (Sold Separately):

• Mounting Brackets: H22-PM-KIT (Pendant Mount Kit)
