Flashes are used in photography to produces an instantaneous flash of artificial light at a color temperature of about 5500 K to help illuminate a scene. This strobe light is simple to use and can be added to almost any lighting system simply by adding to a standard light socket. The front cover works well to diffuse the light, creating a soft, even light for your subject. Please charge your strobe on its AC socket for at least one hour prior to its first use.
