The product is an in-ceiling spotlight system by Lts Licht und Leuchten, type SCER 2.2140 SILBER*, consisting of a 2-flame in-ceiling housing made of sheet steel. The in-ceiling housing is designed for use in ceilings with a thickness of 1 to 35 mm and is installed into the ceiling using adjustable clamping wings, allowing for variable adaptation to different ceiling thicknesses. The inner side of the housing is black lacquered, while the outer side has a silver-colored surface. The installation depth is 140 mm, providing sufficient space for mounting and necessary cabling.

Applications
This system is suitable for use in residential and commercial spaces as well as offices, where a modular and aesthetically appealing lighting solution is required. The modular design allows for individual lighting configuration, as different light heads can be combined. The in-ceiling solution is particularly advantageous in rooms with shallow ceiling structures, as the 140 mm installation depth ensures a compact installation. The maximum ceiling thickness of 35 mm makes the system suitable for many standard ceilings.

Functions and Equipment in Detail
The in-ceiling housing is made of sheet steel and provides a stable base for mounting the light heads. The clamping wings enable easy and secure fastening into the ceiling, with adjustability allowing adaptation to different ceiling thicknesses from 1 to 35 mm. The inner side of the housing is black, minimizing light reflection and improving light output. The outer side is silver-colored, giving the system a modern appearance. The light heads are pre-assembled at the factory, ensuring a secure and precise connection between the light head and the operating device.

Technology Explained Simply
The system is designed as a flexible in-ceiling spotlight system, with the in-ceiling housing forming the electrical and mechanical base. The operating devices are already integrated into the housing, so no additional components for power supply are required. The 140 mm installation depth allows for a compact installation that can be easily integrated into many ceiling constructions. The clamping wings ensure secure fastening without requiring additional fastening materials.

Compatibility and Accessories
Exact compatibility specifications for the light heads are provided in the product descriptions of the individual light heads. The light heads are pre-assembled at the factory, ensuring a direct connection to the operating device in the in-ceiling housing.

Installation and Mounting
Installation is carried out by inserting the in-ceiling housing into the designated cutout in the ceiling, which must have dimensions of 187 x 340 mm. The clamping wings are adjusted to compensate for ceiling thicknesses from 1 to 35 mm and secure the housing in the ceiling. Electrical cabling is done via the integrated operating devices in the housing. The overall dimensions of the in-ceiling housing are 210 x 363 x 143 mm (length x width x height).

Operational Advantages
The system offers a modular and flexible solution for ceiling lighting that can be adapted to different requirements. The simple installation using adjustable clamping wings reduces installation effort. The integrated operating devices in the housing reduce the number of required components and simplify cabling. The silver-colored outer finish and black inner side ensure an attractive appearance and optimized light output. The 140 mm installation depth makes the system suitable for many standard ceilings.

The products comply with CE and RoHS standards, confirming conformity with European safety and environmental standards.
