This is a Photek U-Series 60" (1.5m) Silver Umbrella with a removable 8mm umbrella shaft. Photek U-Series umbrellas are manufactured on a 10-spoke frame, giving them more stability than an 8-spoke frame used by most other umbrella manufacturers.

A white umbrella greatly softens and broadens the light output of any strobe or lower wattage constant light. Silver umbrellas soften, too, but they provide a slightly "harder" light, with specular features in the highlight areas.
