This will give you a precise pattern for where your light will be thrown, it also gives you an idea of drop off and voids.
The Blue Ring Gaffer’s Glass is also used to check the condition of light filament, and to locate the sun when it is behind clouds. The Blue Ring Gaffer’s Glass is not designed to look directly at the sun. Use it only to locate the sun through clouds.
