Live comfortably while saving energy. Enjoy enhanced quality of life, safety, and energy savings with Steinel's intelligent sensor technology. Lights on/off – automatically. Highly innovative sensors respond to movements and lighting conditions, turning the light on instantly and off after a set time. The cost-effective high-frequency sensor light RS 16 L (diameter 275 mm) with E27 socket for bulbs up to 60 watts is ideal for wall and ceiling mounting in hallways, entryways, staircases, or bathrooms. The glass body made of mouth-blown white triplex glass ensures even and soft light distribution. Behind it lies – invisible to the eye – intelligent high-frequency sensor technology that detects the smallest movements regardless of temperature and switches the light on instantly and off after the individually selected time. Easy adjustment of time and twilight threshold via a rotary knob. Additionally, installation is straightforward, as the light and sensor share the same connection – just 2 wires and you're done! There are options for connecting additional devices. Changing the bulb is tool-free, thanks to the screwless glass attachment with a bayonet lock. The chassis is made of high-quality plastic.
