The Photoflex LitePanel Translucent Fabric Diffusion (39 x 39 ) included with the Photoflex LiteReach Plus with 39 x 39 LitePanel Kit offers one (1) stop of diffusion per layer.

The Photoflex Frame for Litepanel Frame/Panel Reflectors - 39x39" - PVC, B&H # PHFLP3939, is a 39 x 39" PVC frame only, which will hold in place an assortment of Photoflex panels, available separately. As indicated under the "In The Box" section under the Overview tab on our website, only the 39 x 39" PVC Frame and the 2-Year Manufacturer's Warranty are included with the purchase of the Photoflex Frame for Litepanel Frame/Panel Reflectors - 39x39" - PVC, B&H # PHFLP3939. There are compatible accessories listed under the Accessories tab on our website. If you are looking for a kit which includes additional accessories packaged with the frame, you would have to consider purchasing one of the kits we list on our website, such as either the Photoflex FirstStudio LitePanel Kit - 39 x 39" (99 x 99 cm), B&H # PHLP3939K, or the Photoflex LiteReach Plus with 39 x 39" LitePanel Kit, B&H # PHLPLR3939K.

It is about a one stop diffusion.

The diffuser in this kit would have a 1 stop light loss on it.
