Modul Q 144 LED ceiling light with DALI dimmer The linear design of the Modul Q 144 ceiling light fits perfectly into modern interiors. The fact that the light was designed entirely in white harmoniously rounds off the purist overall impression. The numerous built-in LEDs have a wide beam and also ensure particularly natural lighting with an above-average colour rendering index. The integrated ballast is equipped with a DALI interface so that the module can be dimmed and the brightness adjusted to changing conditions.
