Abstract: The present invention relates to a horticultural lighting system comprising a first string (22) of at least one light element (16, 40), a second string (24) of at least one light element (16, 40), both strings being electrically connected in parallel with each other, a power supply unit (12, 50,60,70) providing an AC current/voltage to the parallel circuit of the strings, and means for energizing (26, 42) the first string during a first half period of the AC voltage and the second string during a second half period of the AC voltage, so that each string radiates pulsed light, said first string and said second string being arranged such that different areas (32, 34) are irradiated. The invention also relates to the use of the inventive lighting system in an environment where living organisms are irradiated with light, or a greenhouse for exposing plants to pulsed light. Finally, the invention relates to a method of irradiating plants in a greenhouse or other living organisms in a predetermined environment with pulsed light from light elements arranged in two parallel-connected strings, which strings are both adapted to radiate light to different areas, said method comprising the steps of: providing an AC current/voltage, energizing one string during the first half period of the AC voltage for radiating light to a first area, and energizing the other string during the second half period of the AC voltage for radiating light to a second area different to the first area.

The lighting system is also to be used in an environment where living organisms are irradiated with light, or a greenhouse for exposing plants to pulsed light. A corresponding method is also claimed.
