Rendl NONO DIMM R14345 is a round, white LED downlight for recessed ceiling installation. Its broad trim surrounds a slightly recessed light surface, leaving no hanging shade below the ceiling. This white version combines a 3000 K warm-white light source with TRIAC dimming.
Check the opening as well as the visible diameter
The outer diameter is 8.3 cm, while the required ceiling cutout measures 6.5 cm. These dimensions are not interchangeable: one describes the visible trim and the other the opening that receives the fitting. When replacing an existing downlight, compare both measurements before choosing the new fixture.
The drawing shows a body height of 3.2 cm, but Rendl specifies a recess depth of 7 cm. A shallow body therefore does not mean that the same shallow installation space is sufficient. Check the space reserved for the complete assembly and its connections above the ceiling. The installation drawing shows spring mounting.
An included LED source with adjustable brightness
The integrated LED is supplied with the fitting, rather than being a separately selected GU10 bulb. Rendl lists 7 W power and a luminous flux of 560 lm. The 3000 K colour temperature means warm white; consider that colour when combining several downlights with other lighting in the room.
TRIAC dimming allows brightness adjustment using compatible controls. Have the installer check the intended dimmer instead of assuming that every existing controller will work. The declared LED lifetime is 20,000 hours. This is a light-source lifetime figure, not a warranty period.
A recessed option for humid interiors
The manufacturer specifies IP65 and permits use in humid environments. NONO can therefore be considered for a bathroom, as well as ceiling lighting in a kitchen, hallway or garage. A qualified electrician must assess the specific bathroom position. Its unadorned white ring suits modern and minimalist interiors. The fitting operates at 230 V, and the manual requires qualified installation with the power disconnected before work begins.
