Dimmable LED ceiling light Francis with high luminosity The metal band meandering near the ceiling forms the shade of the LED ceiling light Francis. It is equipped with LEDs on the upper and lower edge, so that both indirect ceiling and ambient lighting as well as direct downward light results. Very efficient SMD LEDs have been installed, which produce a high luminous flux. The brightness of the light can be reduced to the desired level via SwitchDim using a 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 %.
