Installation Methods for the Dimmable UFO LED High Bay Light
- Hook Mounting: screw a hook (not included) onto the fixture, then hang it from a chain or ceiling anchor point. A practical solution, perfect for quick installation.
- Ceiling Mounting: attach a flat bracket (not included) to the fixture, then drill the ceiling to anchor it using appropriate plugs and screws. Provides a stable and discreet installation.
- Threaded Rod Mounting: insert a threaded rod (recommended diameter: 22 mm) into the designated hole, then tighten the supplied nuts to secure the fixture. Ideal for metal or industrial structures.
Each mounting method must be performed in compliance with current electrical standards. For optimal detection, the recommended installation height is between 6 and 15 meters. Sensor settings are adjustable via a remote control (not included).
Suitable Spaces for the UFO LED High Bay Light with Sensor
Thanks to its adjustable power and high luminous efficiency, this LED high bay light is ideal for high-ceiling lighting. At 150W mode, it suits spaces of 60 to 90 m². At 200W, it effectively lights areas between 90 and 120 m². At full power (250W), it covers up to 150 m². This fixture is especially recommended for warehouses, factories, hangars, gyms, workshops, or high-storage areas. Its integrated detection technology optimizes light use based on human presence and ambient brightness.

Is the motion detector on the dimmable UFO LED high bay already built in, or does it need to be connected separately?
The twilight motion detector is factory-integrated and 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 operational and automatically manages switching based on detected presence (detection range 12 m, detection speed 0,3 m/s) and ambient light levels.

Does the LED high bay supplied under this reference come with a motion sensor?
Yes, a motion sensor is supplied with the LED high bay reference UHB1220-240W_WH.
Answer from the Silumen technical team · 27/10/2026
What is the 12V cable output on the 240W UFO High Bay LED luminaire used for?
The 12V low-voltage output is intended for power dimming via 0-10V control systems. It allows you to connect a 0-10V compatible dimmer in order to adjust the light output of the luminaire.
Answer from the Silumen technical team · 27/10/2026
How do you adjust the motion sensor settings?
The sensor parameters (range, timer from 10 seconds to 30 minutes, light threshold) are adjustable via a remote control that is not included in the delivery and must be ordered separately.
