LED Ceiling Light SURFACE SENSOR 350 18W/4K IP44 1440LM

The OSRAM/LEDVANCE Surface Circular 350 Sensor LED ceiling light, reference 4058075618008, is a circular surface-mounted luminaire with 18 W designed for indoor lighting with automatic activation via sensor. It delivers a luminous flux of 1440 lm and a color temperature of 4000 K, providing neutral white light suitable for corridors, stairways, bathrooms, lobbies, and other passage areas.

Its high-frequency sensor combines motion detection and ambient light control, allowing the luminaire to switch on only when the configured conditions are met. The detection range, switch-on time, and daylight threshold can be adjusted to suit the needs of each space.

18 W LED ceiling light with 1440 lm

The luminaire integrates an 18 W LED light source capable of delivering 1440 lm, which corresponds to a luminous efficacy of 80 lm/W. Its 120° beam angle provides broad, even illumination from a single ceiling luminaire.

The LED light source is integrated into the unit and is not replaceable. The driver is also built in, so the product is a complete luminaire ready to connect to a 220-240 V power supply.

4000 K neutral white light

Reference 4058075618008 corresponds specifically to the 840 version, with a color temperature of 4000 K and a color rendering index above 80.

Neutral white light provides functional, balanced illumination for common areas, corridors, bathrooms, staircases, and spaces where good visibility is required without an overly warm tone.

Microwave motion sensor

The Surface Circular 350 Sensor incorporates a high-frequency sensor based on microwave technology. This system detects movement within the configured area and automatically controls the switching on of the luminaire.

The manufacturer specifies a detection angle of 120° and an adjustable range of approximately 4 to 7 meters.

Integrated light sensor

In addition to motion detection, the ceiling light includes ambient light measurement. The light sensor threshold can be adjusted between approximately 2 and 50 lux.

This function helps avoid unnecessary switching on when there is sufficient natural light, making it especially useful in circulation areas used intermittently.

Configurable switch-on time

The time the luminaire remains on after detecting movement can be set from approximately 5 seconds to 30 minutes.

This adjustment allows short times in corridors and fast-traffic areas or longer lighting periods in lobbies, staircases, or spaces where users stay for longer.

IP44 protection for ceiling mounting

The luminaire has an IP44 protection rating when installed on the ceiling, providing protection against solid objects and water splashes. This feature makes it suitable for certain indoor areas where a higher level of protection than a conventional ceiling light is required.

Please note that LEDVANCE specifies IP20 when the luminaire is installed on a wall. The product is intended for indoor use only and is not designed for outdoor installation.

Metal housing and PMMA diffuser

The luminaire body is made of steel and uses a PMMA diffuser. This combination provides a robust construction and uniform light distribution.

The finish is white, making it easy to integrate into ceilings and walls in homes, residential buildings, commercial premises, and other indoor spaces.

350 mm circular format

The ceiling light has a diameter of 350 mm and a height of 115 mm. Its weight is approximately 600 g.

Its classic circular design allows surface mounting without the need to recess the luminaire, simplifying use in both new builds and renovations.

Service life of up to 30,000 hours

LEDVANCE declares an L70/B50 service life of 30,000 hours at an ambient temperature of 25 °C. This means that, under the specified conditions, the luminaire is designed to maintain at least 70% of its initial luminous flux during that period.

The stated L80/B10 service life is 22,000 hours and the L90/B10 service life is 15,000 hours. The manufacturer also specifies up to 50,000 switching cycles.

Low flicker and good light quality

The luminaire is classified by LEDVANCE as low flicker. Its color rendering index Ra above 80 provides suitable color representation for general indoor lighting applications.

It also has an RG0 photobiological classification according to EN 62778 and EN 62471.

Not dimmable with a dimmer

The Surface Circular 350 Sensor is not dimmable with a conventional dimmer. The luminaire is controlled through its integrated motion and light sensor and through the configurable parameters of the sensor itself.

Class I and grounding

The luminaire belongs to Protection Class I. Therefore, the conductive metal parts of the housing must be permanently connected to the protective earth conductor during installation.

Electrical connection is made via a 3-pole terminal and must be carried out by qualified personnel.

Operating range from -20 to +40 °C

The luminaire is designed to operate in ambient temperatures between -20 and +40 °C. For storage, LEDVANCE specifies a range of -20 to +80 °C.

IK03 mechanical resistance

The Surface Circular Sensor has an IK03 mechanical resistance rating. It is intended for indoor installations where significant impacts on the luminaire are not expected.

Applications of the Surface Circular 350 Sensor

Thanks to its integrated sensor and automatic lighting, this luminaire is especially suitable for areas where user presence is intermittent.

Automatic lighting for passage areas

The Surface Circular 350 Sensor ceiling light combines 1440 lm LED lighting with automatic motion and light detection. This allows the luminaire to remain off when the room is empty and switch on automatically when presence is detected within the configured range.

Its adjustable sensor, 4000 K neutral light, 30,000-hour service life, and IP44 protection for ceiling installation make it a particularly practical solution for corridors, staircases, bathrooms, and other indoor common areas.

Important: the IP44 rating applies to ceiling mounting; for wall installation the manufacturer specifies IP20. The luminaire is for indoor use only and must be grounded due to its Class I protection.
