Indoor flat downlight Steinel RS PRO P1 flat S PMMA 9.5 W 960 lm IP54 with motion sensor (warm white)

Steinel RS PRO P1 flat S PMMA is an indoor flat downlight designed for compact, protected automatic lighting. The fixture delivers 960 lm of warm white light from a 9.5 W LED source and includes an integrated motion sensor that switches illumination on when movement is detected. Its slim profile and PMMA diffuser provide even light distribution while the IP54 rating ensures protection against dust and water splashes, making it suitable for corridors, stairwells, hallways and utility spaces where reliable, space-saving illumination is required.

Advantages

The integrated motion sensor enables automatic on/off operation, reducing manual interaction and energy use. The PMMA diffuser offers uniform light distribution and a clean appearance while the low 9.5 W power consumption provides efficient illumination at 960 lm output. The flat design supports installation in areas with limited ceiling depth and the IP54 protection class safeguards the luminaire against dust ingress and splash water from any direction.

Suitable for

• Hallways and corridors
• Stairwells and landings
• Utility rooms and storage areas
• Entrances and service areas with compact ceiling space

Key specifications

• Light output: approximately 960 lumens
• Power consumption: 9.5 watts (LED)
• Light color: warm white
• Diffuser material: PMMA (acrylic)
• Protection rating: IP54 (dust protected, splash resistant)
• Integrated motion sensor for automatic switching
• Low-profile, flat downlight design for shallow ceilings

How to use

Install the luminaire on an appropriate indoor ceiling surface following local electrical regulations and using suitable mounting hardware. Connect the fixture to the mains supply with the power isolated before wiring. Adjust sensor orientation and sensitivity if the model allows, positioning the sensor to detect movement across the intended detection zone. After installation and power-up, the integrated motion sensor will switch the LED on when presence is detected and switch off after the selected timeout period.

Recommendations

Position the downlight to cover approach paths and high-traffic zones for reliable activation. Avoid aiming the sensor directly at heating sources or windows that may cause false triggers. For long-term efficiency, pair automatic operation with appropriate timeout and sensitivity settings to balance comfort and energy savings.
