200 lm/W Efficiency
Up to 40,000 lumens at 200W—60% energy savings vs. traditional HID.
IP65 & IK10
Dust-proof, water-resistant, impact-resistant for harsh industrial environments (-40°C to +50°C).
100,000 Hours L90
90% lumen maintenance after 100,000 hours—lowest total cost of ownership.
Advanced Engineering Features
Cutting-edge LED technology, intelligent thermal design, and robust construction for professional industrial applications.
Energy Efficiency

HB21 system efficacy reaches 200 lm/W—twice the brightness of conventional 100 lm/W fixtures with 50% less energy consumption. Achieve energy savings up to 50% with ROI within 24 months.
Thermal Excellence

Modular die-cast aluminum heatsink with vertical fin structure creates chimney effect airflow—passive cooling keeps LED junction temperature below 85°C. Self-cleaning fin design prevents dust accumulation. Fanless silent operation with no moving parts. TM-21 certified thermal performance maintains LED junction at 82°C @50°C ambient.
Smart Control

Multiple sensor technologies available—all options automatically dim to 10% when no motion detected, saving up to 75% additional energy in low-traffic areas.
Installation Versatility

Two professional mounting options to suit different installation preferences and regional standards—both support up to 200W fixtures with tool-free quick-release mechanism.
DIP Switch Adjustable Control

Onboard DIP switches allow installers to adjust power, CCT, and beam angle after installation—no need to order separate SKUs or return fixtures for reconfiguration.
Hygienic Finless Design

The finless, smooth-surface design eliminates dust and debris accumulation points, making HB21 ideal for food processing plants, cleanrooms, and sanitary environments. Easy to clean and maintain—meets hygiene standards for sensitive industrial applications.
Versatile Applications
From industrial facilities to commercial spaces—wherever you need outstanding illumination, HB21 delivers.
