Installation methods for the dimmable UFO LED high bay light
- Hook mounting: Screw a hook (not supplied) onto the light, then hang it from a chain or a ceiling anchor point. A practical solution, perfect for quick installation.
- Ceiling mounting: Attach a flat bracket (not included) to the light, then drill into the ceiling to secure it using suitable wall plugs and screws. Provides a stable, discreet installation.
- Threaded rod mounting: Insert a threaded rod (recommended diameter: 22 mm) into the designated opening, then tighten the supplied nuts to secure the light. Ideal for metal or industrial structures.
Each mounting method must comply with current electrical standards. For optimal detection, the recommended installation height is between 6 and 15 meters. The sensor settings can be adjusted using a remote control (not included).
Suitable spaces for the UFO LED high bay light with sensor
Thanks to its adjustable power and high light output, this LED high bay light is ideal for illuminating high-ceiling spaces. In 150W mode, it is suitable for areas of 60 to 90 m². At 200W, it efficiently illuminates areas of 90 to 120 m². At full power (250W), it covers up to 150 m². This light is particularly recommended for warehouses, factories, hangars, gyms, workshops, and high-ceiling storage areas. Its integrated sensor technology optimizes lighting based on human presence and ambient brightness.

Is the motion sensor on the dimmable UFO LED high bay already built in, or does it need to be connected separately?
The twilight motion sensor is integrated and factory-wired inside the housing: no additional accessories or connections are required on your part. Once the luminaire is powered at 220-240 V, the sensor is fully operational and automatically controls switching based on detected presence (detection range 12 m, detection speed 0.3 m/s) and ambient light level.
