Automatic light control system for a Luminaire with a light source and beam forming light collector with and intense hotspot. The system includes a connector set and a base unit. Immediately thereafter, using the dark image setting previously set, a first dark image is recorded. The adaptive control characteristic is dependent on the signal level and the fixed control characteristic is independent from the signal level. The handrails, along with the footrest, provide the user with balance and safety while getting into and out of the bathtub. The invention concerns the field of micromechanical parts, particularly, for timepiece movements.
