A multi-LED device comprises a transparent substrate, a plurality of light emitting diodes, LEDs, arranged for emitting light of a plurality of colors and disposed on the transparent substrate, an integrated control circuit in connection with the LEDs and comprising a plurality of photo sensors optically connected to the LEDs. Each photo sensor is provided with a color filter. The integrated circuit is arranged for receiving via the plurality of photo sensors information on a light intensity of the plurality of colors of the LEDs and for regulating the light intensity of the colors of the LEDs based on the information on the light intensity. The transparent substrate with the plurality of LEDs is flip-chip mounted on the integrated control circuit.
