Abstract: The present invention provides a medical lighting system (1), in particular an operating lighting system, comprising: a set of light sources (2) for illuminating a determined area and having one or more modifiable optical properties; and a control device (6) for controlling the set of light sources (2), in order to modify said one or more optical properties as a function of a command from a user. In particular, the control device (6) is a control device having a gestural interface and comprising: two sensors (7, 8) mounted some distance from each other, each sensor delivering a signal corresponding to a detection zone and the detection zones of the two sensors (7, 8) including a common detection zone for detecting a gestural command from the user; and analysis means receiving as input the signals coming from both of the sensors (7, 8) and configured to modify said one or more optical properties as a function of said gestural command.
