DOF 23.3inch Softbox Diffuser Kit for F&V K4000 K4000S / Aputure Lightstorm LS 1S 1C LED Studio Panel Light

This is a nice softbox, but it doesn't fit the LS 1C. The LS 1C is rectangular, and this is square; I had to build a 12" x 12" DIY LED panel to use it. BUT, that said, I like the build of the soft box & honeycomb. Wish it had fit my LS 1C, but if you've got a 12"x12" panel in need of a softbox, this is a good fit.

I sent this back because it didn't fit (and I really wanted it to fit!). It was inexpensive for the quality. I'd buy it again in a heart beat if my LED's were 1 inch smaller.
