Lighting designers use City Theatrical Top Hats for three primary reasons:
- To decrease the viewing angle to the lens so the audience doesn't see the bright and potentially distracting source of light.
- To block spill light caused by optical deficiencies in the lighting fixture.
- For decorative purposes, to make a lighting fixture look more "theatrical."
City Theatrical Concentric Rings, Egg Crate Louvers, and Cross Baffles are often used for this purpose as well. Those three reasons illustrate the concept of why designers use Top Hats, but why are Half Top Hats used?
For Standard Half Top Hats, the first three reasons are the same, but there is an important fourth reason to add to the list:
4. To make a lighting fixture "disappear" in the lighting rig.
This is easy to see in a theatre or light lab.
Standard Half Top Hats, like all City Theatrical beam shaping accessories, are made at our factory in Carlstadt, New Jersey, USA.
