Strong aluminum alloy construction lens with heat-protective design and hollow design helps dissipate heat efficiently. When working with lights under 200W, the built-in heat dissipation system makes the temperature of this lens cover lower than similar products, which prevents your hands from being scalded when you are operating. And it makes the light system work normally, too.

*Please turn off the light first and detach the lens until the lens cools.

Four grooves are designed for easily inserting included shutter blades to cut or shape the light projected on the subject. And the fixed design shutter blades suit the grooves well.

Users can choose from 15 pieces of GOBO patterns and insert different GOBO patterns to the light to create various fantastic lighting effects, making the background rich.
