The KONE RL20 ceiling light is an optimized lighting solution for elevator cars. The design emphasizes universal form language, modular installation and a long service life. The unit’s diameter and circumference are carefully designed to fit most common car sizes, and to house a number of LEDs, as required. The LEDs are installed directly on the inner surface of the ring-shaped aluminum frame. The design directs the heat out of the structure, which extends the component lifetime remarkably. Timeless and minimalistic appearance suits most building interiors well, whether from decades past or highly modern.
