This is a 43" Umbrella with a beaded silver reflective surface from Impact. It will intensify and slightly soften the light output of a strobe light fixture.

Umbrellas soften, broaden, and diminish the light output of flash light source. Umbrellas with a white interior will soften and weaken light more than an umbrella with a silver lining. A white umbrella without a black backing may also be used as a makeshift softbox, although the use of the light will not be as efficient as with a lightbox.

Choosing umbrella size is determined by the size of the subject, and the strength of the light supply being used. Choosing an umbrella surface is as subjective as choosing a paint and brush.
