A light emitting device configured to tunably emit light with a total color temperature (CTtot), comprising: a carrier comprising a first major surface and an opposite second major surface, a first light source, arranged on said first major surface, and arranged to emit light with a first color temperature (CT1) tunably adjustable within a first range from a first low to a first high color temperature, a second light source, arranged on said second major surface, and arranged to emit light with a second color temperature (CT2) tunably adjustable within a second range from a second high to second low temperature, a controller configured to individually control the first and second light sources so to tunably adjust CT1 and CT2 from a first state to a second state according to a preselected scheme, by increasing CT1 and decreasing CT2 between said first and second states, such that CTtot remains unvaried.
