H3B Series LED Dome Warning Light

Industrial LED dome warning light with USB / 485 smart control, aluminum housing, and compact integration.

The H3B Series LED dome warning light is suitable for equipment that needs compact form, uniform illumination, and smart control in one indicator. Compared with traditional tower lights, the dome structure works better in limited spaces, visually integrated machine fronts, and stations that require a cleaner appearance.

This series offers USB control, 485 control, and direct power versions for machinery, automation cells, IIoT warehousing, and on-site management systems. With its aluminum housing, diffused PC lens, and multiple interface options, H3B balances control flexibility, durability, and installation convenience.

Available in USB, 485, and direct power versions for different machine control schemes.
One-piece aluminum housing improves structural rigidity, heat dissipation, and durability.
Diffused PC dome lens provides softer and more uniform illumination.
Supports direct nut mounting or side mounting with an L-bracket.

Features

Flexible smart control: USB and 485 versions can be programmed to control on/off, color, brightness, and flashing logic.
Better visual integration: the dome form is suitable for machine fronts, warehouse stations, and compact automation modules.
One-piece aluminum housing: rigid structure, good heat dissipation, and corrosion resistance for industrial use.
Diffused lens design: 360-degree illumination with a softer visual effect and clear machine status indication.
Multiple interface options: supports 0.5 m cable, M12 connector, USB, and RS485 interfaces.
Optional buzzer: available for combined sound-and-light warning above 90 dB.

Applications

Suitable for CNC machinery, automation stations, IIoT warehousing, machine status indication, and industrial projects that need a compact warning light.

When the application needs programmable control, clear visibility, and a cleaner equipment appearance in limited space, H3B is easier to integrate than a conventional tower light.
