Question 1

Why does the STEINEL RS PRO DL 200 SC lamp turn on through a wall?

Accepted Answer

The STEINEL RS PRO DL 200 SC lamp is equipped with a motion sensor that can sometimes detect movements even through obstacles like walls, especially if they are thin or partially open (for example, with windows or openings).

Possible explanations:

Type of sensor: The sensor may use sensitive technologies (such as passive infrared) that detect heat or movement over a wide area.
Thickness and nature of the wall: A very thin wall or one made of materials that allow certain waves to pass through may enable the sensor to perceive movement from the other side.
Positioning of the sensor: If the sensor is placed close to a wall or in a corner, it may pick up movements in adjacent areas.
Sensor settings: The sensitivity of the detector can be adjusted. Too high sensitivity may cause false triggers.

Tips to limit this phenomenon:

Reduce the sensitivity of the sensor if possible.
Reposition the lamp to avoid having the sensor facing areas where it might detect movements through a wall.
Check the environment to eliminate other sources of movement or heat that could trigger the lamp.

These adjustments generally help to limit unintended activations through walls.

Question 2

How to replace the bulb of the STEINEL LS 150 S lamp?

Accepted Answer

To replace the bulb of your STEINEL LS 150 S lamp, follow these simple steps:

1. Turn off the power

Before any handling, ensure that the lamp is turned off and unplugged from the electrical outlet to avoid any risk of electric shock.

2. Access the bulb

Depending on the model, it may be necessary to remove a cover or diffuser to access the bulb. This may involve unscrewing a few screws or gently unclipping the protection.

3. Remove the used bulb

Unscrew the bulb by turning it counterclockwise if it is a screw bulb. If the bulb is a push-fit type, gently pull it outwards.

4. Install the new bulb

Insert the new bulb by screwing it in clockwise or gently pushing it in depending on the type of bulb.

5. Replace the cover or diffuser

Replace and securely fasten the cover or diffuser to protect the bulb.

6. Restore power and test

Plug the lamp back in and turn it on to check that the new bulb works correctly.

Tip: Only use bulbs compatible with the LS 150 S model to ensure optimal and safe operation.

Question 3

What should I do if my STEINEL LS 150 S lamp does not turn on?

Accepted Answer

If your STEINEL LS 150 S lamp does not turn on, several checks should be made in the following order to identify the cause of the problem.

Check the power supply
Start by checking that the lamp is properly plugged in. Ensure that the power cable is securely connected and that no circuit breaker in the electrical panel has tripped. Test the power outlet by plugging in another device (lamp, charger, etc.) to confirm that it is supplying power. If the circuit fuse is tripped, reset it or replace it if it is faulty. In case of a detected short circuit or damaged cable, check the cable using a voltage tester before reusing the lamp.

Check the switch and reset the system
The lamp switch must be in the ON position. After each turn-off, a pause of about 1 second is necessary before the motion sensor reactivates. If the lamp still does not activate after motion detection, perform a reset by cutting off the power for a few minutes and then restoring it. The electronic system automatically performs a self-test of about 1 minute after being powered on, during which the detector is not yet active.

Check the trigger threshold settings
The LS 150 S has an adjustable twilight threshold. If the adjustment button is set to the sun symbol, the lamp operates in daytime mode (regardless of ambient brightness). If it is set to the moon symbol, the threshold is automatically adjusted (approximately 2 to 1,000 lux). A poor setting of this threshold may prevent the lamp from turning on. Gradually adjust this button to adapt the sensitivity to your environment. For a daytime test, position the button on the sun symbol.

Check the motion sensor and detection area
The infrared motion sensor of the LS 150 S detects movements at an angle of 240° with a range of up to 12 meters (in tangential mode). Ensure that nothing obstructs the sensor (dirt, debris, spider webs). Gently clean the sensor lens with a soft cloth. Also, ensure that the detection area is correctly configured and does not encounter obstacles. The lighting duration is adjustable from 10 seconds to 15 minutes: a duration that is too short may give the impression that the lamp turns off immediately.

Diagnose a failure of the light source
Unlike other floodlights, the LED source of the LS 150 S is not individually replaceable. If you have checked all the previous points (power, switch, settings, sensor) and the lamp still does not light up upon motion detection, the light source may be defective. The LED lifespan is 50,000 hours, but a manufacturing defect is possible. In this case, you will need to replace the entire floodlight.

Contact customer service if necessary
If none of these steps resolve the issue, contact the retailer or the claims service of STEINEL France SAS (29 rue des Marlières, 59710 Avelin) providing your proof of purchase. The STEINEL LS 150 S lamp is covered by a 3-year warranty against material or manufacturing defects.
