The article 100442 from Vossloh-Schwabe is a lamp holder for compact fluorescent lamps, specifically designed for T8 tubes with a diameter of 26 mm. It serves as a socket for secure fixation and electrical connection of the light sources in luminaire constructions. The holder is made of steel and is bright zinc-plated, ensuring high corrosion resistance and long-lasting surface quality. The design with a through-hole allows for easy mounting on luminaire bodies or other carrier structures using screws.

Sockets for compact fluorescent lamps are used in numerous lighting systems, particularly in industrial and commercial environments, where reliable and maintenance-friendly fixation of light sources is required. The lamp holder 100442 is designed for use in luminaires that employ T8 compact fluorescent lamps with a diameter of 26 mm. It ensures stable mechanical fixation and secure electrical contact of the lamp.

Functions and equipment in detail include the use of steel as the base material, protected against oxidation by a bright zinc-plated surface. The socket is equipped with a through-hole intended for mounting with screws in sizes M4 or M3.5. This mounting option allows for flexible integration into various luminaire constructions. The precise fit for T8 lamps with a 26 mm diameter ensures accurate and smooth insertion of the light sources.

Technology explained simply shows that the lamp holder primarily fulfils a mechanical and electrical function. Mechanically, it securely holds the fluorescent tube in position, preventing shifting or loosening during operation. Electrically, it provides the necessary contacts for power supply to the lamp. The use of zinc-plated steel ensures high mechanical strength and durability, especially in environments with increased humidity or low corrosion exposure.

Compatibility and accessories refers to use with T8 compact fluorescent lamps having a diameter of 26 mm. The holder is not designed for other lamp types such as T5, T12, or LED modules. Mounting is done via the through-hole using screws M4 or M3.5, with the exact screw size to be selected according to the luminaire construction.

Mounting and installation is carried out by securing the lamp holder to the luminaire structure using the designated screws. Positioning is done so that the lamp can be correctly inserted into the socket and the electrical contacts lie securely. Mounting is simple and requires no special tools, except a screwdriver or an appropriate screwdriver bit for the selected screw size.

Advantages in operation lie in the robust construction from zinc-plated steel, ensuring long service life and high reliability. The precise fit for T8 lamps with a 26 mm diameter prevents loose contacts and ensures even light output. Simple mounting and maintenance facilitate use in industrial and commercial installations, where quick replacement and minimal downtime are essential.
