What Is the DB-LSL-IP20-01S-1W-PIR?
Direct answer: The DB-LSL-IP20-01S-1W-PIR is a 1W recessed indoor step light with an integrated PIR motion sensor. It is designed for stairs, corridors and passageways where the light needs to activate automatically when movement is detected.
The light and sensor are integrated into one 86 × 86 mm faceplate. This avoids installing a separate visible motion sensor beside the step light.
When Should the PIR Version Be Selected?
| Project Condition |
Selection Guidance |
| Lighting should activate when someone approaches |
Select the PIR version. |
| Lighting is controlled by a separate switch or building system |
Consider the standard DB-LSL-IP20-01S-1W. |
| Dry indoor staircase or corridor |
The IP20 PIR model can be considered. |
| Outdoor, damp or exposed staircase |
Select a product with suitable ingress protection instead. |

What PIR Information Must Be Confirmed Before Ordering?
A PIR label alone is not enough for project selection. The following operating details should be confirmed against the actual staircase or corridor layout:
- Detection distance: The required sensing range.
- Detection direction: How people approach the sensor.
- Installation height: The planned height above the floor or step.
- Hold time: How long the light should remain on after movement.
- Ambient-light trigger: Whether activation is required only when the surrounding area is dark.
These sensor values are not shown in the supplied product data and should be verified before the model is approved for a project.
What Problems Can Incorrect Sensor Selection Cause?
- The light may activate too early or too late.
- Movement across the stairs may not enter the expected detection area.
- An unsuitable hold time may not match the time needed to use the staircase.
- The light may activate when the surrounding area is already sufficiently bright.
Providing the mounting height and expected movement direction helps avoid selecting the sensor only by appearance.

Frequently Asked Questions
Does this light include the PIR sensor?
Yes. The PIR sensor is integrated into the front faceplate.
What is the PIR detection distance?
The detection distance is not stated in the supplied product information. Confirm the required range before ordering.
Can it be installed on an outdoor staircase?
No. The product is rated IP20 and is intended for dry indoor areas.
Is the PIR model the same size as the standard model?
Yes. Both supplied specifications show an 86 × 86 × 30 mm product size and an 80 × 80 × 50 mm cut-out.
What should be included in a project enquiry?
Send the quantity, mounting height, expected detection range, movement direction, hold-time requirement, CCT, finish and project location.
Request a Sensor Configuration Check
