The replacement bowl 7403N from Trilux is a replacement part for wall- and ceiling-mounted luminaires of the 7403N series as well as for the Mondia WD3 model. It serves as a cover and protects the internal lighting components from external influences, while simultaneously ensuring uniform light distribution. The bowl is made of opal white material, which provides diffuse, glare-free illumination and maintains the light quality of the luminaire. It is specifically designed for indoor use, where clean and functional aesthetics are required.

Replacement bowl for existing luminaires of the 7403N series is required when the original cover is damaged, soiled, or impaired by aging. The bowl replaces the previously installed cover without changing the mechanical or electrical connection conditions. The shape and dimensions are identical to the original parts, ensuring direct interchangeability.

Functions and equipment in detail
The bowl has an outer diameter of Ø 512 mm and a height of 132 mm. These dimensions fit exactly to the specified luminaire models and ensure secure installation without additional adjustments. The opal white material ensures uniform light diffusion, avoiding glare and optimizing light distribution in the room. The surface is smooth and easy to clean, simplifying luminaire maintenance.

Technology explained simply
The bowl is not an electrically active component, but a purely mechanical and optical protective and diffusion body. It is mounted onto the luminaire structure and protects the light source and reflectors from dust, moisture, and mechanical damage. The opal white coating or material composition ensures that light does not pass directly through the cover, but is diffused, creating a pleasant lighting environment.

Compatibility and accessories
The replacement bowl is specifically designed for wall- and ceiling-mounted luminaires 7403N as well as for the Mondia WD3 model. It is an original replacement part from Trilux, featuring the same technical and optical properties as the series model. Compatibility is ensured by identical dimensions and precise form fit. There are no specific accessories that must be combined with this bowl; it is directly attached to the existing luminaire.

Installation and mounting
Installation is carried out by removing the old bowl and inserting the new one into the luminaire's designated holders. Fastening is typically done via a clamp or screw connection, which varies depending on the luminaire model. No additional tools or special mounting aids are required. Installation is straightforward for electrical trade professionals.

Installation into existing luminaires of the 7403N series and Mondia WD3 is performed without changing the electrical or mechanical connection conditions. The bowl is simply inserted into the existing holder and secured. The luminaire's light function remains unchanged, as the bowl does not perform any electrical functions.

Advantages in operation
Using the replacement bowl 7403N enables cost-efficient maintenance of existing luminaires, as only the damaged or soiled component is replaced, not the entire luminaire. Optical quality is preserved, and light distribution matches the original specifications. The bowl is easy to clean and resistant to everyday indoor stresses. Using an original replacement part ensures the luminaire's safety and functionality after replacement.
