A lamp system is provided, comprising a lamp with a lamp housing accommodating a plurality of light sources for emission of visible light, including blue light, a time keeping unit, a light sensor for sensing intensity of light incident upon it, and a light controller configured for controlling the plurality of light sources in response to the intensity of light sensed by the light sensor and the time provided by the time keeping unit, characterized in that the lamp emits blue light for a selected time period, wherein the blue light has a luminous flux ranging from 50 lux to 200 lux and, preferably, an irradiance that is larger than 5 mW/nm/m2 in a selected wavelength range, such as in the wavelength range from 440 nm to 500 nm, as measured at a distance of 3 metres from the lamp.
