This dome cover arrives standard with each Einstein Flash unit. For use with Einstein E640 flash units ONLY. Arrives with instructions for installation. | The Buff Dome Cover is a frosted pyrex dome that lowers UV emission from the flashtube while shielding the Einstein lamp and tube from harm. | The modeling lamp filament is in the exact same focal point as the UV-coated flashtube, resulting in an incredibly close relationship between the flash and modeling light. The Buff Dome Cover equalizes the effective size and shape of the modeling lamp and flashtube. | Lowers color temperature by approx. 300K
