Frequently asked questions

Sensor lights

What is a sensor light?

A sensor (lat.: "sentire" = to feel) can measure certain physical and chemical properties and convert them into an electrical signal that can be further processed.

In the case of sensor lights, the sensor measures ambient brightness, heat from people or ultrasonic waves. The resulting electrical signal can then switch the luminaire on or off.

How do STEINEL SensorLights work?

Welcome home

The future belongs to automatic light. And not just outdoors, where the STEINEL invention is already a standard feature of homes and farms. With the development of state-of-the-art high-frequency sensors, STEINEL has made this technology of the future socially acceptable for indoor use too. As a result, maximum energy efficiency and optimum living comfort can now also be achieved inside buildings - powered by STEINEL.

The innovation is hidden inside the luminaire. A high-frequency motion detector that welcomes you and your visitors with light when you enter the room and turns it off when it is no longer needed. Welcome home. Welcome to the future.

Individual setting of response brightness, duty cycle and range.

Easy installation: luminaire and sensor = 1 connection

Available as wall and ceiling lights in various designs 
36 months manufacturer warranty.
5 years glass after-sales warranty.

All STEINEL lights are suitable for energy-saving and LED light sources.

Light ON and OFF ...automatically

An innovation from STEINEL - the original. STEINEL high-frequency (HF) sensors detect movements without delay and without any restrictions on "sensitivity" due to ambient temperature and direction of movement of the object to be detected.

The high-tech sensors send out signals and in the next instant receive the echo reflected from the walls and surrounding objects. A movement in the detection area is registered by the sensor within fractions of a second due to the changed echo image and the light is switched on immediately! After an individually adjustable follow-up time, the light switches off automatically.

STEINEL high-frequency sensors operate at 5.8 GHz. Since glass and thin walls pose no obstacle to these signals, the sensors can be mounted invisibly inside the lights from the outside. So nothing interferes with the attractive design of STEINEL SensorLights.

The power of approx. 1 mW corresponds to only approx. 1/1000th of a radio telephone.

Elegant comfort
You don't see intelligence, you just notice it. STEINEL HF technology is invisibly concealed inside the attractive lights and provides light "just in time".

There's no way around STEINEL's HF SensorLights. They seamlessly detect even the smallest movements within a 360° radius and at a distance of up to 8 m. If required, the range can be electronically reduced steplessly to as little as 1 m.

Attentive light
The detection range of STEINEL HF SensorLights is ideal for indoor applications. All-round detection of 360° means they can be installed on the wall or ceiling as required.

Time setting
STEINEL HF SensorLights are equipped with a timer that ensures the light stays on for the set duration. The desired lighting duration can be set continuously between 5 sec and 15 min.

Twilight setting

Setting the response threshold between 2-2000 lux determines at which ambient brightness the sensor light should become active. Already during the day or only at dusk or in darkness.

Modernization in the twinkling of an eye
STEINEL HF SensorLights are installed exactly like conventional lights. No additional work or cable connections are required. On the contrary: Complicated cross switches and corresponding cable routing can be dispensed with without replacement. There's no simpler and more convenient way to invest in the future.

Simple assembly
STEINEL HF SensorLights are just as quick and easy to install as conventional lights: Attach the light to the wall or ceiling and screw the phase and neutral conductors into the luster terminals - that's it. Only manual switching on and off is no longer necessary thanks to integrated sensor technology.

Connection of further consumers
A large proportion of the HF sensor lights have a separate connection terminal with which a further consumer can be switched on. When entering the guest toilet, for example, another light or a fan is switched on with the light. The switching capacity is max. 100 watts.

How to connect a sensor light?

The installation must be carried out professionally in accordance with the installation regulations customary in the country.

Five safety rules apply here:

  • Disconnect
  • Secure against reconnection
  • Establish absence of voltage at all poles
  • Ground and short-circuit
  • Cover or fence off adjacent live parts. 

  • A detailed description of the installation for the individual products can be found on our Youtube Channel or in the operating instructions.
How to set a sensor light?

With sensor lights, just like with a motion detector, you can make three different settings individually: Time, twilight threshold and range. These are product-specific, e.g. attached to the underside of the luminaire.

The time is specified in seconds and minutes, and the range in meters. The Lx, on the other hand, is the unit for illuminance, with 100,000lx corresponding to a bright sunny day and 0.001lx to a starry night. The motion detectors are adjustable up to 2000lx.

Frequently asked questions

Solar lights / solar lamps

How do I dispose of solar lamps?
Solar lamps must not be disposed of with general household and residual waste, as they contain electronic components and rechargeable batteries. Since the consumer is legally obligated to dispose of these parts properly, there are collection points at the municipal level or they can be returned to the dealer.
How do LED solar lights work?

The process of converting solar energy into electrical energy takes place regardless of the choice of illuminant.

LED illuminants have advantages in that the energy consumption is much lower than with conventional illuminants. This means that the energy obtained can be used even more effectively.

How long do solar lamps take to light up?
Before using the solar light for the first time, the battery is completely discharged. To prevent permanently minimized battery performance, the battery must be fully charged before the first use. In principle, solar lights can light up after the first few minutes of converting solar energy, but only for a very short time. The solar lamp should charge all day so that it has enough energy to shine at night.
Why do solar lamps need batteries?
The batteries of a solar lamp store the energy generated during the day. At night, the battery then feeds the lamp with this energy.
Why do solar lamps only glow in the dark?
Solar lamps can shine at any time of day, just like other lamps. However, the light is useful to the consumer only from a certain level of daylight. Especially solar lights need the time of day so that there is enough electrical energy for the night.
What are solar lights?
Solar lights are lights whose energy is obtained by solar energy with the help of solar cells.
How does a solar light / solar lamp work?

Each solar light has a solar cell consisting of processed silicon. STEINEL solar lights feature the monocrystalline solar panel, which is highly efficient compared to polycrystalline and amorphous solar panels and can convert solar energy even when it is cloudy.

In the cell, the supply of light and heat (solar energy) releases positive and negative charge carriers, generating electric current (photovoltaics) that, in the case of STEINEL solar lights, charges a lithium-ferrum battery. In some products, this has a lighting reserve of up to 60 days at 20 switching operations per night, 2500 mAh capacity and is temperature-resistant from -20 to +40 degrees.

The battery feeds the STEINEL LED system from the converted solar energy, which can illuminate an area of up to 30sqm with 150 lumens at 1.2W. The highest efficiency is 124 lm/W.

STEINEL solar lights also feature a powerful infrared sensor that switches light only when it's really needed. The 140-degree sensor with Fresnel lens integrates perfectly into the design.

To make the solar lights even more efficient, STEINEL has built software into the light that sets up a permanent automatic demand analysis and takes care of reserve control.

How good are solar lights?

The combination of monocrystalline solar panel, STEINEL LED system, infrared sensor, lithium-ferrum battery and intelligent control system is what makes STEINEL solar lights in particular highly efficient and so successful.

Solar energy is free and virtually inexhaustible, which means a great deal of energy can be saved, which is of great importance to both people and the environment.

The solar panel made of monocrystalline silicon oxide has the highest efficiency of all silicon processing. Moreover, silicon is the second most abundant element in the earth's crust.

Due to the fact that solar cells provide relatively little power, the combination with LED lamps is optimal, because they are much more energy efficient with higher light output.

In many cases, the solar light is combined with a twilight switch that turns on the light as soon as it gets dark. However, if the solar light has a sensor, light is also only switched on when it is really needed.

So for the consumer, the solar light offers a lot of convenience - on and off are switched automatically, you do not have a complex installation by cables and power laying, and the setting is easy to do.

How bright are solar lights?
The brightness of solar lights depends on the illuminant. Solar lights with the STEINEL LED system achieve 150 lumens at 1.2W, with the highest efficiency at 124lm/W.
How to charge solar lamps / solar lights?
Solar lamps do not need manual charging. The electric current generated by solar energy, is stored in a lithium-ferrum battery during the day, so that it can power the lamp at night when it is in motion. Some lights can be charged in advance via a mini-USB cable.
How long do solar lamps burn?
With solar lights from STEINEL, a light reserve of up to 60 days can be achieved with 20 switching operations per night.
How to clean solar lamps?

The solar lamp and solar panel are best cleaned with a soft cloth and a mild cleaner.

However, the compatibility of the cleaner with the surface should be checked beforehand to prevent possible damage.

Frequently asked questions

Spotlight / Outdoor spotlight

What is a LED spotlight?
LED spotlights contain LED bulbs, which have 12 times higher luminous efficiency compared to conventional bulbs at 150 lm/W 12. Lifetime (30 years) and energy efficiency (saving 90 percent) are also much higher.
What are spotlights?
Spotlights are available in different variants, whether as floodlight, LED or with motion detector. Depending on where they are installed, they provide comprehensive illumination of an area and thus provide the user with safety and comfort.
What are LED spotlights good for?

LED illuminants offer many advantages for the consumer:

High energy efficiency: the fact that efficiency decreases as electronic power increases means that less power is consumed for optimum function. The combination of STEINEL sensor technology and state-of-the-art LED technology can thus save over 90 percent energy.Long life: To protect the LED from overheating, STEINEL has developed a unique cooling system. This makes it possible to achieve a real service life of 30 years and more.Light efficiency: LEDs are significantly brighter in comparison - with less energy consumption.Despite the higher purchase price, LED light sources are far more economical than conventional incandescent lamps.

How do outdoor spotlights work?

STEINEL outdoor floodlights are predominantly equipped with an infrared sensor.


Infrared sensors react to the heat radiation of moving persons and switch e.g.: the lighting on and after an adjustable time off again.

Mode of operation:
Every body with a temperature above absolute zero (-273.5°C) emits electromagnetic radiation. In the case of the human temperature range, this radiation is in the infrared range. The so-called passive infrared motion detectors use this fact.
The heart of the infrared sensor technology is a so-called pyrosensor. This electronic module reacts when the infrared heat radiation within its detection range changes, i.e. when a person enters the detection range. The resulting voltage jump is converted by the system into an electronic pulse that switches the light.

Range: (Passive Infrared)
The range of STEINEL infrared sensors depends on the direction of movement. On average, the range is approx. 12m with tangential movement (parallel to the sensor), shortening with radial movement (towards the sensor).
Solar emitters, on the other hand, make a difference. In addition to the infrared sensor, these are equipped with a solar panel and energy-efficient LED spotlights.
How do STEINEL floodlights work?

Light sensation: The LED powerhouse

STEINEL is already making future technology accessible to everyone. In the XLed Home spotlight, high-performance LEDs ensure perfect illumination and sensationally low energy consumption.

The new high-tech floodlight needs less than 15 watts to bathe the surroundings in glistening light. The incredibly high efficiency is made possible by the use of LEDs as illuminants and an innovative control system. These modern components have another major advantage: compared to halogen lamps or incandescent lamps, they have an almost unlimited service life. The long service life is aided by STEINEL's Active Thermo Control technology, which protects the LEDs from overheating.

Because the floodlight generates only a fraction of the heat of conventional floodlights, it can be mounted under canopies without any problems. The extremely swivelling light panel can be optimally aligned with the area to be illuminated.

Intelligent light switching is provided by STEINEL's IR sensor technology, which has been tried and tested a million times over and is also used in the IS 140-2 motion detector. The combination of LED technology and sensor control results in savings of 90% compared with conventional halogen floodlights.

Sensor-switched halogen floodlight

STEINEL Sensor-Switched Halogen Floodlights are the ideal solution for illuminating house fronts, driveways and vulnerable areas with extra brightness. These vigilant floodlights are designed for light sources of varying strengths from 150 to 500 watts of light output. This automatically puts special eye-catchers in the right light, welcomes guests and effectively deters the uninvited. The STEINEL range offers the right model for every application, from the low-cost HS 5140 Fresnel lens floodlight to the microprocessor-controlled HS 500 high-tech floodlight. The HS 150 and HS 300 floodlights are fitted with a ceramic reflector.

Setting options

The detection range can be precisely adapted to local conditions by means of the horizontally and vertically swiveling multi-lens (HS 150 DUO, HS 300 DUO, HS 500 DUO) or Fresnel lens (HS 5140) and can be restricted with the enclosed cover panels.Simple setting of time and twilight threshold via rotary control.

Light ON. Light OFF.
Sensor controlled
Automatic luminaires are implemented with the help of motion sensors. Two different technologies are used here: For indoor areas, RF sensors are the optimal solution; for outdoor areas, only passive infrared (PIR) sensors are used.

Heat radiation as a remote switch

The heart of a PIR sensor system is a so-called pyrosensor. This electronic component reacts to changes in the incident infrared heat radiation with a change in voltage. Since every person emits infrared radiation due to their body heat, they inevitably change the thermal image detected by the sensor when they enter the system's field of view. The resulting voltage jump is processed by the electronics to switch light.In order to be able to react to movements within the detection range, the sensor systems are equipped with a segment lens. It divides the field of view of the pyrodetector into active and passive (not visible to the sensor) zones. If a heat body crosses a zone boundary, the IR radiation received changes for the sensor and it emits a signal.

Multisensor technology
STEINEL has developed multisensor technology for particularly high demands on the size of the detection zone. Here, two or even three pyro sensors are arranged at a special angle to each other within the system so that their detection ranges add up.

Segment lenses
STEINEL Multilens Technology

Multi-lens technology (MLT) enables seamless monitoring of a hemispherical detection area. It is thus the optimal lens system for motion detectors with dual or triple sensors.

Fresnel lenses

Fresnel lenses offer the simplest way to segment the detection range of an infrared detector. A group of individual lenses is arranged in a circular segment. With a maximum detection angle of 180°, an area of up to 225m2 can be reliably monitored. A second optical window for the area below the main detection zone makes it almost impossible for the sensors to creep underneath.


STEINEL sensors generally have a max. range of 12m, which can be shortened if the direction of travel is radial (towards the sensor).

How does an infrared heater work?

Infrared sensors react to the heat radiation of moving persons and switch e.g.: the lighting on and after an adjustable time off again.

Mode of operation:
 Every body with a temperature above absolute zero (-273.5°C) emits electromagnetic radiation. In the case of the human temperature range, this radiation is in the infrared range. The so-called passive infrared motion detectors use this fact.

The heart of the infrared sensor technology is a so-called pyrosensor. This electronic module reacts when the infrared heat radiation within its detection range changes, i.e. when a person enters the detection range. The resulting voltage jump is converted by the system into an electronic pulse that switches the light.


The range of STEINEL infrared sensors depends on the direction of movement. On average, the range is approx. 12m with tangential movement (parallel to the sensor), which is shorter with radial movement (towards the sensor).

How bright are LED spotlights?
White LED light sources achieve a luminous efficacy of 150 lm/W. For comparison, the luminous efficacy of conventional incandescent lamps is just 12 lm/W. This makes the white LED light source 12 times more efficient.
How much wattage does an outdoor LED spotlight need?
When it comes to the wattage, it all depends on the intended use. In general, the wattage required for STEINEL LED outdoor floodlights is 25-62 W.

Frequently asked questions

Connected lights and spotlights

Which products can be interconnected?

All STEINEL Bluetooth products, whether outdoor light, spot or floodlight, can be interconnected. Other Bluetooth product makes, however, cannot be interconnected with STEINEL products.

Can you integrate these products into a smart home system?

At the moment, they can't be integrated into a smart home system, but our developers are working on ways of resolving the problem.

What distance do I need to allow between the products?

The minimum distance for Cube lights and the 800-series is 5 m to avoid inadvertent activation by the iHF sensors. But if you do ever wish to install the products more closely together, simply deactivate the sensor on every second product via an app. For all other products, there is no need to observe any minimum distance. The maximum distance between any product should not be any more than 30 m.

How many products can I interconnect?

In theory, any number of products can be interconnected. However, a new network should be opened if you are interconnecting more than 100 products.

How well is the wireless control system protected from unauthorised access?

A password can be set for both the installation level and the user level. This can prevent unauthorised access. Alternatively, Bluetooth access can be completely deactivated and will only be reactivated for 60 minutes after a power reset.

Can the products also be set without an app or smartphone?

The Cube-series products can be set on the product itself and also using the app. All other products can only be operated via the app.

Why has STEINEL opted for Bluetooth?

To begin with, Bluetooth is a standard that has proven its high level of communication reliability for many years, it is available on virtually every terminal device and, supporting the low-energy standard, uses an extremely low level of energy - much less than Wi-Fi, for example. Then, of course, it requires no bridge/gateway in the way that other wireless protocols do, such as Zigbee.
