Donut, 17.5in Source Four Reaches operational temperature in 30City Theatrical Donuts are used in the color frame slot of an ellipsoidal reflector spotlight to sharpen gobo projections. Similar to the way the human eye sharpens focus when it squints, a donut reduces the aperture and sharpens the output of the fixture. There is some reduction in brightness to achieve this increase in sharpness, but this is often a tradeoff that designers are willing to make. Note: white painted donuts are Make to Order.
