The invention provides a lighting device (1) comprising: —one or more light sources (10) configured to provide light source light (11); —a luminescent element (5) comprising an elongated luminescent body (100) having a radiation input face (111) for receipt of the light source light (11), the luminescent element (5) comprising a first luminescent material (120) for conversion of at least part of the light source light (11) into luminescent material light (8); —a light guide element (850), configured downstream of the first luminescent material (120), and configured to light guide at least part of the first luminescent material light (8); —a second luminescent material (1120), configured downstream of the first 10 luminescent material (120), at a first distance (d1) of at least 0.5 mm thereof, configured to convert one or more of (i) at least part of the light source light (11) and (ii) at least part of the first luminescent material light (8) into second luminescent material light (1128) having a spectral power distribution differing from a spectral power distribution of the first luminescent material light (8); 15—a light transmissive optical element (24) configured downstream of the light guide element (850), configured to receive at least part of the first luminescent material light (8) of the light guide element (850) and to receive at least part of the second luminescent material light (1128), and configured to transmit the received luminescent material light (8) and the received second luminescent material light (1128), and configured to beam shape at least part of the received luminescent material light (8), and to provide lighting device light (101) comprising one or more of the light source light (11), the first luminescent material light (8) and the second luminescent material light (1128).
