The Nobile Downlight 5068 ECO Flat is an LED recessed luminaire for use in spot and general lighting applications. With a power rating of 8 watts and a colour temperature of 3000 Kelvin, the luminaire produces warm white light suitable for living and working spaces. The luminaire is specifically designed for ceilings with limited recess depth, making it particularly suitable for suspended ceilings where space for deeper recessed solutions is restricted. The front glass is clear and enables uniform light distribution, while the heat sink made of aluminium die-cast ensures efficient heat dissipation. The luminaire's surface is either powder-coated or galvanised, providing a robust and durable coating.

Applications

The luminaire is intended for indoor use, particularly in residential and office buildings, where discreet yet effective lighting is required. Due to its shallow recess depth, it is especially suitable for rooms with low ceilings or in buildings where deeper recessed solutions are not feasible. The luminaire is only suitable for installation in suspended ceilings and must not be installed in ceilings covered with insulation material, as this could impair convection and affect the luminaire’s cooling.

Functions and Equipment in Detail

The luminaire features a front glass that evenly distributes light output and a heat sink made of aluminium die-cast for efficient heat dissipation. The surface is either powder-coated or galvanised, ensuring high mechanical and chemical resistance. The luminaire is designed for a recess diameter of 68 mm, enabling universal installation in standard concrete recess housings. Specifically tested are recess housings from the brand KAISER, particularly the HaloX® 100 with tunnel 190 (type 1281-30) and HaloX® 180 with tunnel 190 (types 1282-72/1282-75). The luminaire is not intended for outdoor use.

Technology Explained Simply

The luminaire has a rated power of 8 watts and a colour temperature of 3000 Kelvin, corresponding to warm white light. The light output is defined by a 38° beam angle, enabling a focused yet not overly narrow light distribution. The colour rendering index (Ra) is 90, meaning colours are reproduced well and naturally under this lighting. The colour deviation (MacAdam) is 3 SDCM, ensuring high colour consistency over the luminaire’s lifetime. The lifespan is 50,000 hours (L80 B10), meaning that after 50,000 operating hours, 80% of the original light output remains and no more than 10% of the luminaires will have failed. The operating current is 350 mA.

Compatibility and Accessories

The luminaire is to be operated with an external driver. Recommended drivers are models EL-8R-350 (art. no. 8999038350) and EL-8R-350 D (art. no. 8999028350). The EL-8R-350 model is not dimmable, while the EL-8R-350 D model is dimmable via phase-cut. The luminaire is not intended for operation with other drivers, especially not with dimmable drivers not explicitly mentioned. Compatibility with the specified drivers is specified by the manufacturer.

Installation and Mounting

Installation is carried out in suspended ceilings, ensuring sufficient convection. The luminaire must not be covered with insulation material, as this could impair cooling and lead to overheating. The recess housings must have a diameter of 68 mm. Installation is performed in standard concrete recess housings, with the specifically tested KAISER models (HaloX® 100 and HaloX® 180) recommended. Mounting does not require special tools, but proper wiring and secure fastening are required.

Operational Advantages

The luminaire features high light quality, with a colour rendering index of 90 and colour consistency of 3 SDCM. The 50,000-hour lifespan (L80 B10) ensures long service life and low maintenance costs. The shallow recess depth allows flexible installation in rooms with limited space. The use of aluminium die-cast for the heat sink ensures efficient heat dissipation, increasing reliability and lifespan. The luminaire is designed for indoor use and requires no additional protection against moisture or dust.
