Rendl SOLIS 40 DIMM R14344 is a black LED ceiling light with a circular frame and a milky diffuser set slightly behind its lower edge. Rather than exposing individual bulbs, it presents one broad light surface with a clearly defined black outline. This is a surface-mounted fitting with integrated LEDs, not a recessed downlight or a pendant on a suspension cable.
A 39.5 cm diameter and an 8 cm projection
Use the 39.5 cm diameter stated on the manufacturer's product page when planning its position. The number 40 in the name identifies the size variant. Its body projects 8 cm from the mounting surface, without needing room for a hanging cable. This is a useful distinction when comparing a ceiling-mounted fitting with a pendant above furniture or a circulation route.
The plain circular shape and absence of decorative arms support modern and minimalist interiors. Its black perimeter surrounds a light centre, so consider the contrast against your ceiling and the appearance of nearby fittings as well as the overall diameter.
Warm light with TRIAC dimming
The integrated LEDs are rated at 50 W, with a colour temperature of 3000 K and a declared luminous flux of 3750 lm. There is no separate screw-base bulb to choose. The milky diffuser covers the light source, while the warm colour temperature distinguishes this version from neutral-white ceiling lighting. Brightness can be adjusted using TRIAC dimming. Plan for a compatible dimmer rather than assuming that any lighting controller will work.
Placement and installation
The manufacturer lists ceiling-lighting applications in living rooms, bedrooms, kitchens, hallways, children's rooms, offices and shops. Choose SOLIS for general illumination; its lumen figure alone does not determine how many fittings a particular room needs. Room dimensions still matter when planning the lighting layout. The installation instructions require a qualified installer and disconnection of the power supply before work. Handle the diffuser carefully: the manufacturer specifically warns that it can be damaged during installation.
