In the scene, a white lamp and nozzles of different colors. To obtain a black lamp, just assign the material of the black nozzle to the "Rinbok_body" object.

Reflector object "Rinbok_reflector", by default without anti-aliasing. For visualization
from a near-angle perspective I recommend to apply the TurboSmooth modifier to this object.

Diameter: 95 mm
Height: 100 mm
