Impact Diffuser Sock Overview

This 13" Diffuser Sock from Impact is a 13" nylon fabric light softener ringed with strong elastic for a snug fit around standard-sized light head reflectors. This convenient diffuser softens light output by creating a larger light surface across the face of the reflector, bathing your subject in a diffuse light that's perfect for portrait or beauty photography and video. It installs in seconds, and is a handy way to quickly diffuse a light source, when setting up a softbox or using a handheld diffuser is impractical.

Diffuser Socks are stackable, offering the capability to increase the diffusion effect by adding additional socks over the first. Each layer of diffusion reduces light output by 1-stop. The nylon fabric is heat resistant and won't yellow or burn from the heat of your flash, studio strobe modeling light, or a cool light source, like LED or fluorescent lights.

Note:
Intended for use on flash heads, LED sources, or fluorescent sources. Do not use on continuous hot light sources like halogen, tungsten, or HMI lamps.
  • Fits over 13" reflectors
  • Diffuses and softens light output by 1 stop
  • Stackable for increased diffusion
  • Heat resistant - won't yellow or burn

    Must have for smaller reflectors

    Quick to deploy and no major shifts in light quality. If you're using smaller lights like the Storm 80C, this is a must have.

    Asked by: Dom
    A Profoto Magnum Reflector is a bit larger than 13 , so this sock would have a very tight fit.

    Do you have this product in a size to cover a 7" reflector?
    Asked by: Ron
    Unfortunately they do not make it in a 7" size. The band is elastic so you could use a 13" and pull it farther back. It would not be very snug but it can function.
