A lamp (10) is provided comprising a light source (11) and a reflector (12) for redirecting light from the light source (11) into a main direction. The reflector (12) comprises a plurality of holes (13) for allowing part of the light from the light source (11) to leave the lamp (10) in a direction extending from the light source (11) through the reflector (12). The holes (13) in the reflector (12) have reflective inner walls (31, 41) and are dimensioned and oriented such that any light rectilinearly propagating from the light source (11) into the holes (13) is reflected by the inner walls (31, 41) at least once before leaving the holes (13).
