• HB20 is positioned as a higher-power, heavy-duty industrial high bay with broad lumen output, advanced thermal management, wide beam options (e.g., 12°, 25°, 40°, 60°), and smart control readiness (0-10V, DMX, DALI). It’s optimized for industrial and large facilities with demanding performance requirements such as warehouses, factories, and high-ceiling spaces.

• HB21 is generally a cost-effective high-bay solution suited for typical industrial or commercial high ceilings. It offers efficient illumination and can support dimming but is oriented more toward standard warehouse/production areas where extreme temperatures or very high output aren’t required.

Quick positioning:

Use HB20 for heavier industrial / high-temperature / high output requirements and HB21 for cost-efficient, general high-bay illumination in warehouses and commercial spaces.

A clean, straightforward high-bay design like HB21 benefits environments where maintenance and hygiene matter, including:

• Production halls and manufacturing areas

• Food processing facilities where dust and contamination control are critical

• Warehouses and logistics centers with frequent cleaning

• Retail zones with high-ceiling lighting needs

Clean design also typically means fewer exposed fasteners and smoother housings, which are easier to keep dust- and debris-free.

space layout:

• Higher ceilings (10–20 m): use narrow to medium beam angles (e.g., 25°–40°) so light reaches the floor with minimal spread and better vertical illuminance.

• Medium ceilings (6–10 m): medium beams (40°–60°) balance coverage and intensity.

• Lower ceilings or open floor areas: wide beams (60°–120°) offer broad coverage and reduce dark zones between fixtures.

Proper selection ensures uniformity and minimizes glare or dark spots, and in industrial spaces is best confirmed with a photometric layout.

To make a lighting layout for HB21/HB20 series, you’ll typically need:

• Space dimensions (length, width, ceiling height)

• Mounting height and fixture locations

• Target illuminance levels (horizontal/vertical lux requirements)

• Workflow zones or task areas

• Control requirements (dimming protocol, sensors)

• Environmental conditions (temperature, dust/humidity)

These allow proper selection of wattage, optics, mounting pattern, and controls for even coverage and energy efficiency.

Effective high-bay installation should consider:

• Mounting method: use sturdy hook, chain, or pendant mount as appropriate for ceiling height and structural conditions.

• Aim direction: align fixtures so light is directed onto work surfaces—not into walkways or eyes.

• Spacing: follow recommended fixture spacing relative to mounting height to avoid dark spots (often spacing = 1 to 1.5× mounting height as a starting point).

• Control integration: install sensors or dimming interfaces (0-10V, DALI) if required for zoning and energy savings.

• Maintenance access: ensure fixtures are reachable for cleaning and future maintenance without heavy disruption.

Good installation improves uniformity, reduces glare, and maximizes the lifespan of the lighting system.
