Aluminum Flashlight

Dark blue anodized flashlight angled downward in a black room, its beam cutting through the air and spreading across the floor below.
Close view of the flashlight's knurled head, the beam pooling brightly on the ground just beyond it.

An anodized aluminum flashlight lighting its own scene — the beam is volumetric light inside the render, thinning as it travels and pooling on the floor. Modeled, lit and animated in Blender.
