What sensor technologies are used?
Floodlights with sensors use various technologies to detect motion or light levels. The type of sensor determines the lighting's response and its suitability for specific situations.
Passive infrared (PIR) motion sensors
The most common sensor in floodlights is the Passive Infrared (PIR) motion sensor. This sensor responds to changes in infrared radiation, or heat, emitted by moving objects such as people or animals. As soon as a heat change is detected within its detection range, the floodlight activates.
- Adjustability: Most PIR sensors are adjustable for detection distance (typically 2 to 14 meters), detection angle (often between 30 and 180 degrees), and the duration of illumination after detection (from a few seconds to several minutes). This allows installers to tailor the lighting to the specific environment and minimize unwanted activation from, for example, passing vehicles at a distance.
- Location choice: When positioning, consider the sensor's direction relative to heat sources, direct sunlight, or areas frequented by pets to prevent false alarms.
Dusk-to-dawn sensors for automatic activation
A dusk-to-dawn sensor, also called a lux sensor, measures the amount of ambient light. When the light level drops below a preset value (for example, at dusk or on an overcast day), the floodlight automatically turns on. As soon as it becomes light enough again, the light switches off.
Some floodlights combine a motion sensor with a dusk-to-dawn sensor. This ensures the motion sensor is only active when it's dark, preventing unnecessary activation during the day.
Orientation light: subtle presence with full activation
An advanced variant is the floodlight with an orientation light and motion sensor. These lights typically operate at a low brightness (e.g., 10% of maximum power) as soon as it gets dark. When motion is detected, the light temporarily switches to full brightness before returning to the dimmed orientation light. This provides continuous, subtle lighting that switches to full power when needed. This is particularly functional for walkways and entrances where continuous basic lighting is desired, combined with extra light during activity.
Applications for floodlights without a sensor
These floodlights are versatile for places where a constant light output is needed, regardless of motion or daylight. Below are some situations where they prove their value:
| Application | Primary benefit | Additional remarks |
|---|---|---|
| Burglary prevention and security | Deterrence and warning | The sudden light deters unwanted visitors. Place at access points, dark corners, and garages. |
| Paths, driveways, and entrances | Ease of use and safety | Automatic light on arrival or departure. Prevents tripping in the dark. Choose a wide detection angle. |
| Garden lighting | Ambiance and functionality | Lighting that turns on with motion in the garden. Some models with orientation light provide a continuous, soft glow. |
| Business parks and warehouses | Energy saving and efficiency | Illuminates specific zones only when staff or vehicles are present. Contributes to lower operational costs. |
| Billboards and facades | Targeted lighting on demand | Less common, but possible for objects that do not need continuous illumination but still require immediate attention upon passage. |
Illuminating facades and billboards
For accentuating architectural features or illuminating billboards for extended periods, floodlights without a sensor are a solid choice. They provide uniform lighting for the entire set duration.
Sports fields and large areas
On sports fields, construction sites, or company car parks, a constant, powerful light source is needed to ensure safety and visibility. Floodlights without a sensor can provide the basic lighting here.
Gardens and landscape architecture
To illuminate trees, ponds, or specific garden objects for long periods in the evening, these floodlights offer a beautiful solution. The light source stays on, creating a consistent ambiance.
Courtyards and driveways
A well-lit courtyard or driveway increases safety and comfort. By choosing a model without a sensor, the lighting can be on for the desired period, regardless of any movement.

Technical considerations when purchasing
For the proper operation and lifespan of a floodlight with a sensor, several technical specifications are important. It is particularly valuable for installers to consider these when selecting the right fixture.
Selecting the correct IP rating
The IP rating (Ingress Protection) indicates the degree of protection against dust and water. Since floodlights with sensors are mainly used outdoors, a suitable IP rating is crucial for durability.
- IP44 (splash-proof): Suitable for sheltered places such as under a canopy or eaves.
- IP54/IP55 (dust and splash-proof): Offers more protection and can be used in places directly exposed to rain.
- IP65 (dust and waterproof): Suitable for almost all outdoor conditions, resistant to water jets. A common rating for most outdoor floodlights.
- IP66 (fully dust and waterproof): For locations exposed to severe weather conditions or high-pressure cleaning.

Impact resistance with the IK rating
The IK rating (Impact Protection) indicates the degree of impact resistance of a fixture. This is important in environments where there is a risk of vandalism or accidental impact. Ratings range from IK00 (no protection) to IK10 (protected against 20 joules of impact). For outdoor floodlights, an IK rating between IK05 and IK08 is often recommended.
Light color and light output
The light color, expressed in Kelvin (K), influences the atmosphere. Warm white (2700K-3000K) is often chosen for atmospheric lighting for homes and terraces. Cool white (4000K) and daylight white (6500K) are more suitable for functional lighting on driveways, parking lots, or at entrances where optimal visibility is desired.
The light output, measured in Lumens, determines how bright the floodlight is. Higher Lumen values are needed for illuminating large surfaces or for security purposes.
Installation tips for the installer
Correctly installing a floodlight with a sensor guarantees optimal operation and safety. Some practical considerations:
- Determine position: Place the floodlight so that the sensor has a clear view of the area to be monitored or illuminated. Avoid places where trees, bushes, or other obstacles can block the detection field or cause unnecessary activation by wind.
- Mounting: Use the supplied mounting hardware and ensure a stable installation on a solid surface such as a wall or pole. Many floodlights come with a swiveling or tilting bracket, allowing for precise adjustment of the light beam.
- Connection: Ensure a safe and waterproof electrical connection. Use a suitable, grounded power cable and, if necessary, a waterproof junction box (IP65 or higher) to protect connections from weather influences.
- Adjust sensor: After installation, adjusting the sensor is crucial. Set the sensitivity (range), the light duration, and the dusk level (lux level at which the lamp turns on). Test the settings by walking through the detection area to ensure the lamp responds as desired and does not switch on unnecessarily.
- Testing: Perform a comprehensive test in both daylight and darkness to verify the correct operation of both the motion and dusk sensors.
