The Nobile Downlight 5068 ECO Flat IP44 is an LED recessed luminaire for use in spot and general lighting. With an installation diameter of 68 mm and a flat design, it is particularly suitable for ceilings with limited installation depth. The luminaire is installed exclusively in suspended ceilings, ensuring sufficient convection and avoiding coverage with insulation material. The heat sink is made of aluminium die-casting, and the front glass is integrated. The surface is either powder-coated or galvanised, ensuring robust and long-lasting construction.

Applications
This luminaire is suitable for indoor lighting in residential and commercial spaces where a flat, discreet recessed solution is required. Due to its IP44 protection rating, it is also suitable for damp rooms such as bathrooms or kitchens, provided there is no direct spray water exposure. The combination of low profile and high light output makes it an ideal solution for limited space under ceilings.

Functions and Equipment in Detail
The luminaire features a colour rendering index of Ra 90, enabling natural and clear colour representation. The colour deviation is 3 SDCM (MacAdam), ensuring high colour consistency throughout its lifetime. The lifespan is 50,000 hours (L80 B10), meaning that 90% of the luminaires will still emit at least 80% of their original light output after this period. The light colour is 3000 K, i.e. warm white, and the light distribution occurs with a beam angle of 38°, providing a focused yet sufficiently broad illumination.

Technology Explained Simply
The luminaire is equipped with LED technology offering high energy efficiency. The operating current is 350 mA, indicating a compact and efficient power supply. Recommended operating devices include models EL-8R-350 (non-dimmable) and EL-8R-350 D (dimmable via phase-cut). The dimmable version allows brightness adjustment via phase-cut dimmers, which is useful for flexible lighting control in residential and office spaces.

Compatibility and Accessories
The luminaire can be installed in all common concrete recessed enclosures. Specifically tested are the recessed boxes from KAISER: HaloX® 100 with tunnel 190 (type 1281-30) together with front part (e.g. type 1281-11) and HaloX® 180 with tunnel 190 (type 1282-72/1282-75). These recessed boxes ensure secure and stable installation. As suitable accessories, the dimmable LED driver EL-8R-350 D (art. no. 8999028350) is specified, which is required for phase-cut dimming.

Installation and Mounting
Installation is carried out in suspended ceilings, with the recessed box selected according to the specified types. The luminaire is not designed for direct installation in solid ceilings or without an appropriate recessed box. Mounting is done by inserting into the recessed box and subsequent securing, with electrical connection made via the driver.

Operational Advantages
The luminaire offers high light quality with good colour rendering and low colour deviation. The long lifespan reduces replacement needs and maintenance costs. The flat design enables flexible installation in rooms with limited ceiling height. The IP44 protection rating extends the application range to damp rooms, although the luminaire is not designed for direct spray water exposure. The use of a separate driver allows flexible adaptation to existing electrical systems and dimming controls.
