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.
