City Theatrical 2406 245MM Top Hat For Source Four Strand SL Fixtures

Lighting designers, production electricians, and venue technicians use a top hat when a fixture throws light where it does not belong. Weak optics or a poorly maintained lens can send stray light into the audience or across scenery, and a lens-end extension gives the crew a physical fix at the fixture instead of a compromise in the focus.

It also solves a sightline problem. Audience members and camera operators often find a bare, bright source objectionable, and shielding the lens narrows the angle from which that source can be seen. That matters on theatrical, concert, and broadcast rigs where house and camera positions look straight at the units.

City Theatrical lists this part for Source Four, Strand SL, Shakespeare, and Pacific fixtures, and it also works with S4 PARNel, S4 Zoom, and S4 14-degree units, so a mixed rig can share one accessory type. Skip it on 70 or 90 degree lens tubes, where light loss is extreme. For dedicated, repeatable spill and glare control, it is a more consistent choice than improvised flags or tape.
