120W-200W • 200 lm/W • 3-in-1 Adjustable
An ultra-thin, ultra-light industrial and commercial high bay light featuring 3-in-1 adjustable wattage, color temperature, and beam angle. Designed for diverse environments—from clean food processing plants to warehouses and retail halls—offering maximum flexibility, energy savings, and reduced SKU pressure.
Switch between 60°/90°/120° beam angles via DIP switch to match coverage requirements—no tools or lens replacement needed.
Fewer models, lower inventory, more flexibility.
Select 60%, 80%, or 100% power via DIP switch to match ceiling height and illumination requirements—optimize energy consumption without compromising light quality.
Switch between 3000K-6500K CCT ranges to customize lighting ambiance for different applications—warehouses, retail, food processing, or mixed-use spaces.
Industry-leading LED high bay engineered for maximum flexibility, energy efficiency, and long-term reliability in demanding industrial environments
On-site adjustable power, CCT, and beam angle—one fixture replaces 9 SKUs for maximum inventory efficiency
Up to 40,000 lumens with only 200W—reduce energy costs by 60% vs. traditional HID fixtures
Dustproof, waterproof, and impact-resistant for harsh industrial environments (-40°C to +50°C)
Maintains 90% lumen output after 100,000 hours—minimal maintenance and lowest TCO
Cutting-edge LED technology with intelligent thermal design and robust construction for professional industrial applications
With system efficacy up to 200 lm/W, HB21 delivers twice the light of conventional 100 lm/W fixtures while cutting power consumption by 50%. This means up to 50% energy savings and an ROI in as little as 24 months compared with legacy high-bay systems.
Low glare design reduces eye strain and improves worker productivity
Anti-yellowing PC lens maintains optical clarity for 100,000+ hours
Accurate color rendering for quality control and safety inspections
Independent testing confirms >90% uniformity ratio at 10m mounting height—ideal for warehouses, manufacturing facilities, and distribution centers requiring consistent illumination.
Modular die-cast aluminum heat sink with vertical fin architecture creates chimney-effect airflow—passive cooling maintains LED junction temperature below 85°C.
Vertical orientation prevents dust buildup and maintains thermal efficiency
Zero noise, zero moving parts—ideal for noise-sensitive environments
Optimized thermal pathway extends LED and driver lifespan to 100,000+ hours
TM-21 certified thermal performance maintains LED junction temperature at 82°C @ 50°C ambient—ensuring stable lumen output and color consistency throughout fixture lifecycle.
Choose from multiple sensor technologies to match your specific environment—all options automatically dim to 10% when no activity is detected, saving up to 75% additional energy in low-traffic areas.
12m radius 360° coverage—penetrates obstacles like racks and pallets for reliable detection in warehouses
Cost-effective passive detection for retail and low-ceiling applications—10m range with adjustable sensitivity
Automatically adjusts brightness based on natural light levels—ideal for facilities with skylights or windows
In a 24/7 warehouse with 50% occupancy, motion sensing can reduce energy costs by $180/fixture/year @ $0.12/kWh—achieving payback in under 18 months.
Two professional mounting options to suit different installation preferences and regional standards—both support up to 200W fixtures with tool-free quick-release mechanisms.
U-shaped hook design with adjustable suspension chain—popular for warehouse and industrial applications in North America
O-ring suspension system with safety cable—globally recognized standard for commercial and retail installations
Both systems support 6-15m ceiling heights with field-adjustable tilt angle up to ±30° for optimal light distribution
Compatible with existing HID/metal halide mounting infrastructure—reduce installation costs by 40% when upgrading legacy high bay systems to LED technology.
On-board DIP switches allow installers to adjust wattage, CCT, and beam angle after installation—no need to order separate SKUs or return fixtures for reconfiguration.
Adjust between 120W, 160W, and 200W to match ceiling height and lux requirements
Choose from 3 pre-set color temperature ranges for different environments
Optimize light distribution for narrow aisles, open warehouses, or mixed layouts
All adjustments can be made with fingers—no screwdriver required. Clear labeling and tactile switches ensure accurate settings even in low-light conditions.
