Kamerar 180° Adjustable Multi-Angle Light Stand Adapter with LED Panel Mount, 1/4” and 3/8" Threaded Screw on ⅝” Stud, Angle Adjustment Knob

The stitching came unraveled on the very first use and created a gap where the diffuser material is sewn to the side. Bummer.

These definitely defuse light as expected. Easy to set up. Appear to be of decent quality. However, the light that is output is reduced when these are on. There is a space between the barn doors and the filters that light escapes from. Not a tight seal. Also these are smaller than I'd prefer. I got the largest version, and they are still smaller than I'd like. Perhaps a larger surface area would help get more light on the subject? I found using these I need more power on the lights versus without these.

Bang for your buck, yes. I really like the locking ring on the pop outs too. Very portable and easy to use. Great diffuser. I bought 4.

The media could not be loaded.  LED panels do no angle down with barn windows. This basically allows you to do that and more since this is solid metal. Solves the problem masterfully and it is worth every penny.

I'm a professional videographer. Today's LED panel lights are great, but most of the widely used small LED panel lights provide very harsh lighting, especially when lighting talent. The so-called 'diffusers' that come with most of the panel lights provide very little diffusion because they're placed right on top of the LED panel. I was looking for a portable option for mobile setups. This diffuser works well. The key is to get the diffuser off the light panel for best performance, which this option does well while folding down into a very portable package. If your LED panel light has mostly-otherwise useless barn doors, you will not need to worry about using velcro straps to attach to the light as the barn doors will hold it on. I'm using this on a GVM 480LS or 800D as a key light. The size actually increases the light source significantly while providing a much softer quality of light. Fantastic!Those stating this does not make a difference are quite incorrect. The diffuser provides a much more flattering light source, especially for talking head shots, etc. Great product and will be purchasing at least one more.

These soft boxes do help to create softer light and they fit nicely on the Neewer 660 LED lights with having to take off the barn doors... The build quality is also of great quality However, there is a downside... The diffuser panels in the soft box in pretty dang thin, and I still sometimes can get too harsh of light so you do have to be very mindful with these soft boxes more than other brands. other than the learning curve of what their limits are they are a great buy for someone who is just starting out with lighting for photo or video, but if your more of a simi-pro or professional then you might want to look for something that has a little better diffuser to create that smooth softer light.

Man i love this Stand Adapter it the best one yet that does what i need. i will buy again from this seller

This seems to work great, soften the light and folds down for stowing/portability. I’ve had one issue already, my c stand took a spill, and this got a major gash across the white portion and some of the black. It wasn’t a terrible spill so I first didn’t even know it happened. I assume the light will now spill through the tear diffusion which means replacing at another $50, and I’ve only had it 2 weeks or so. I wish the materials were a bit stronger in this case.Also note: if you want to gain full control a panel light attached this this, you need a c stand. Otherwise the light is stuck in one position, as this diffuser keeps it from moving around in its u shaped bracket. I picked up a c stand and can now use it to really get the light where a I need it, but that ran $150 for the Neewer Heavy Duty.

Only issue that prevents me from giving it a full 5 stars is that the support arms don’t have pockets to sit in. They sometimes slip out. Other than that this is a fantastic collapsible softbox and works very well. I am using this with my neewer 660 led panels.
