Dimmable LED ceiling light Francis with high light output The metal strip that meanders near the ceiling forms the lampshade of the LED ceiling light Francis. It is fitted with LEDs on the upper and lower edges, providing indirect Deck and ambient lighting as well as direct downward light. Highly efficient SMD LEDs have been installed to generate a high light output. The brightness of the light can be reduced to the desired level using Switchdim, practically via the conventional wall switch: When switched once, Francis shines with 100 % luminous intensity, when switched twice it still shines with 50 % and when switched three times, the brightness is reduced to 25 %.
