The Nobile Downlight A 5068 T Flat IP44 is an LED recessed luminaire for use in spot and general lighting applications. The device is particularly suitable as a problem solver for ceilings with limited installation depth and is installed in suspended ceilings. The luminaire features a front glass, a real glass reflector, and an aluminium heat sink, which ensures efficient heat dissipation. The enclosure surface is either powder-coated or galvanised, providing a robust and long-lasting coating. The IP44 protection rating makes the luminaire suitable for use in damp rooms, such as bathrooms or kitchens, where a certain degree of splash water protection is required.

Applications

The luminaire is designed for use in residential and commercial rooms, particularly in rooms with limited ceiling thickness. Due to its shallow installation depth, it is especially suitable for renovation projects or installations in existing ceiling structures where no deep recesses are available. The IP44 protection rating allows use in damp environments, although the luminaire is not intended for outdoor use. The recessed luminaire is not designed for installation in roof or flat ceilings, but exclusively for suspended ceilings.

Functions and Equipment in Detail

The luminaire features an integrated power supply unit, dimmable via phase-cut dimming. This allows adjustment of light intensity according to specific needs, for example, for ambient lighting or reduced brightness in the evening. The connection box is equipped with through-wiring (L, N, PE) and features push-in terminals, enabling simple and secure connection to the electrical supply. The light colour corresponds to colour temperature 927, which is warm white. The colour rendering index Ra is 90, ensuring good colour rendering. The colour deviation (MacAdam) is 3 SDCM, indicating high colour consistency and minimal variation in light colour between different luminaires.

Technology Explained Simply

The aluminium heat sink ensures that the LED technology does not overheat during operation, extending the luminaire’s lifespan. The lifespan is 50,000 hours (L80 B10), meaning that after 50,000 hours of operation, 80% of the original light output is still achieved and at most 10% of the luminaires will have failed. The luminaire is equipped with a real glass reflector, which ensures even light distribution and high light output. The glass front panel protects the internal optics and ensures clear light emission.

Compatibility and Accessories

The luminaire can be installed in all common concrete recessed enclosures. Specifically tested are the recessed boxes from the brand KAISER: HaloX® 100 with tunnel 190 (type 1281-30) together with the front part (e.g. type 1281-11) as well as HaloX® 180 with tunnel 190 (type 1282-72/1282-75). The required installation diameter is 68 mm. The luminaire is not designed for installation in roof or flat ceilings, but exclusively for suspended ceilings.

Installation and Mounting

During installation, minimum convection should be ensured, as the luminaire must not be covered with insulation material. This is necessary to ensure sufficient heat dissipation and to secure the luminaire’s lifespan. Mounting is carried out into the designated recessed boxes, with wiring done via the integrated connection box with push-in terminals. The recessed luminaire is not intended for use in roof or flat ceilings.

Operational Advantages

The luminaire offers high light quality with a colour rendering index of 90 and colour consistency of 3 SDCM. The dimmable function via phase-cut dimming enables flexible use. The lifespan of 50,000 hours (L80 B10) ensures long-term use and reduces maintenance effort. The IP44 protection rating makes the luminaire suitable for damp rooms, although the recessed luminaire is not intended for outdoor use. The shallow installation depth allows flexible installation in existing ceiling structures.
