1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Steinel RS 16 L S Glass Ceiling Light with 360° Motion Detector. Please read these instructions carefully before use and retain them for future reference.
The Steinel RS 16 L S is an economical high-frequency detector lamp (275 mm diameter) designed for wall and ceiling installation in indoor areas such as corridors, entrances, stairwells, or bathrooms.

5. Setup and Installation
The Steinel RS 16 L S is designed for straightforward installation on ceilings or walls. Ensure the power supply is off before proceeding.
5.1 Mounting Location
Select a suitable indoor location such as corridors, stairwells, bathrooms, kitchens, or cellars. The IP44 rating makes it suitable for areas with moderate moisture, but not for direct water exposure.
5.2 Wiring
The lamp and sensor share the same connection, requiring only two wires for power. Connect the live (L) and neutral (N) wires from your mains supply to the corresponding terminals on the fixture. Ensure all connections are secure.
5.3 Securing the Fixture
Use the provided mounting hardware to securely attach the plastic chassis to the ceiling or wall. Once the chassis is mounted and wired, install an E27 bulb (max. 60W) into the socket. The glass cover attaches without screws using a bayonet fitting, allowing for tool-free bulb changes.


6. Operating Instructions
The integrated high-frequency sensor provides automatic light activation based on movement and ambient light levels. The settings can be adjusted using the rotary controls located on the fixture.
6.1 Sensor Functionality
The 360° high-frequency sensor detects movement independently of temperature. It can detect objects through light building materials such as wood, glass, and lightweight partitions. This allows for discreet integration of the sensor behind the glass cover.

6.2 Adjusting Settings
The following settings can be adjusted via rotary controls:
- Detection Range: Electronically adjustable from 3 to 8 meters. Rotate the control to set the desired detection radius.
- Twilight Threshold: Adjustable from 2 to 2000 lux. This setting determines the ambient light level at which the sensor becomes active. For example, a lower lux value means the light will only activate in darker conditions.
- Time Setting: Adjustable from 5 seconds to 15 minutes. This controls how long the light remains on after motion is detected and no further motion is sensed.


6.3 Additional Load Connection
The fixture includes a connection option for additional loads, such as a bathroom fan or WC ventilation system, allowing them to be activated simultaneously with the light.
6.4 Permanent Lighting
The interior lighting with motion detector is designed for permanent lighting operation if desired, depending on the specific wiring configuration and settings.
7. Maintenance
Regular cleaning and inspection will help maintain the performance and appearance of your Steinel RS 16 L S ceiling light.
- Cleaning: Disconnect power before cleaning. Wipe the glass cover and plastic chassis with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the surfaces.
- Bulb Replacement: Ensure power is disconnected. The glass cover can be easily removed via its bayonet fitting for tool-free bulb replacement. Replace with an E27 bulb, maximum 60W.
- Inspection: Periodically check for any signs of damage to the wiring or fixture. If any damage is found, disconnect power and consult a qualified electrician.
