City Theatrical 2571 Short S4 Mini Standard Top Hat

Top hats solve two problems on stage and in broadcast: light landing where it should not, and the lamp being visible where it should not. When fixture optics are marginal or lenses are not well maintained, stray output can reach the audience or wash scenery. A top hat at the lens end gives lighting designers and electricians a fast, repeatable fix without recutting the rig.

This short S4 Mini version suits theatrical, corporate, and television lighting where fixtures sit close to sightlines and cameras pick up any exposed source. It is listed for Source Four, Strand SL, Shakespeare, and Pacific fixtures in the 19 to 50 degree lens tube range. Avoid use in 70 or 90 degree lens tubes, since extreme loss of light will result. For production shops stocking spares, a purpose-built top hat from City Theatrical is easier to standardize across a rig than improvised flags or tape.

Specifiers weighing top hats against barn doors or flags should note the difference: a top hat works evenly around the lens, so it trims spill and glare in every direction at once instead of one side at a time. That makes it a practical first choice for fixtures aimed near the house.
