The RAB H22 Series is a family of precision die-cast UFO LED high bays engineered for the most demanding commercial and industrial environments — combining complete field-adjustability with the industry’s most rigorous washdown, impact, and food-safety certifications. Two models and two voltage options cover every facility from mid-size warehouses to the largest industrial plants: H22 (100–150W, up to 24,005 lm) and H22XL (150–240W, up to 36,461 lm), each available in 120–277V and 480V. Three parameters are field-selectable on every model — wattage, CCT (3000K / 4000K / 5000K), and beam angle (60° / 90° / 105°) — yielding 27 configurations per SKU. CRI 85 (4000K), IP69K high-pressure/high-temperature washdown rated, IK10 impact rated, NSF certified, UL listed for wet locations, and DLC Premium listed across the full family. 7-step MacAdam Ellipse color consistency. Rated life 100,000 hours. Backed by RAB’s 5-year limited warranty.

Smart & Control Features

All H22 family models support the Lightcloud Blue (LC Blue) wireless control ecosystem and plug-and-play sensor accessories via the standard sensor receptacle:

• MVS50: MVS 15M height IP65 occupancy sensor — sold separately
• MVS50/LCB: LC Blue controller with integrated MVS sensor — sold separately

Typical Applications

• Food Processing & Commercial Kitchens: IP69K + NSF certification makes the H22 family the spec-correct choice for washdown zones, food prep lines, and HACCP-compliant facilities across both voltage options
• Warehouses & Distribution Centers: H22 for mid-height racking (12–28 ft); H22XL for tall ceilings and high-cube facilities (18–35 ft)
• Large Industrial Facilities with 480V Distribution: H22/480 and H22XL/480 eliminate step-down transformers — drop-in for high-voltage panels
• Manufacturing & Heavy Industrial Facilities: IK10 impact rating and -40°C cold-start handle the full range of production floor environments
• Cold-Storage & Refrigerated Warehouses: -40°C cold-start rated — powers on at full output in freezer environments
• Gymnasiums & Recreation Facilities: CRI 85 and H22XL’s 36,461 lm handle large open-ceiling venues; adjustable beam angle optimizes coverage pattern
