now have 6 lamps with almost identical function and size to this lamp, so I will refer to my experiences with those lamps for comparison. This is a small battery LED (bi-color and fully RGB) with probably the coolest design of all the lights I have, and very simple operating modes. This version of the light is stealth black on black on the back so if someone tries to use it the first time it's hard to read what each button does, but it looks cool and doesn't have the bright white paint if that happens in the picture. I would like the scrolling of the buttons to provide faster action (e.g. it takes a while to scroll to 100% or to 1%) and I feel like the brightness isn't as strong as some of my other similar lamps, but the color temperature measures very accurately and the battery seems to last very well. I have pictured the LEDs at 4000K with 1% brightness to show the number of LEDs and arrangement. I've owned MANY K&F products over the years, including tons of ND and VND filters, tripods, etc., and these lights fit the same high-end build quality as the other K&F products. There are two magenta on the back that you can slightly see through the transparent back. They hold REALLY well on nice flat metal surfaces, but even on a round post they can hold if placed properly. It comes with 1/4 20 screw holes on the top and bottom, and a 1/4 20 cold shoe holder is included. It's worth noting that there is no cold shoe slot built into the lamp itself (for stacking lamps), so you'll need a 1/4 20 to 1/4 20 screw to connect two together. Not a deal breaker, but I often plug my lights in during storage to keep them all together. The overall performance is great, and the build quality and style (if that matters) can't be beat. These are beautiful lights!

This is not my first video light, and I’m sure this is a good video light. Color of RGB can be changed easily and the battery last relatively long, at least 2 hours as I tested. Will buy the second one if needed.

As someone who makes YouTube videos, I’ve accumulated a lot of little RGB lights over the years, but this is by far the coolest, I’ve seen. The overall design is similar to what you’re used to in that it has a CCT mode, RGB mode and some pre-set scene modes, but it’s the overall execution of how these are employed that really sets this little light apart from the others. The style is quirky and cool. It comes in a package that literally looks like a box of tofu. And where others would have boring buttons or sliders, this light uses giant knobs on the side have a fun retro-modern kind of vibe that actually work just as good as they look. From the bottom knob, you can switch it on, turn to CCT mode, RGB mode or the scene modes. The top button allows you to change the intensity of the settings in the various modes, i.e.: brightness, saturation, etc. And of course there’s a magnetic back and not one, but two tripod mounts - one on the bottom and one on the top. This is a really well-designed little RGB light that stands out in a crowded market place of similar lights. This light both looks great and works great - definitely would recommend.

VERY LIGHT AND EASY TO USE I GIVE IT TWO THUMBS UP I USED IT THIS PAST THANKSGIVEING TO SAVE SOME MEMORIES

They screw on pretty smooth it have a quality threads, and it work just fine. Perfect for someone who's only going to be casually using their step up rings, I am a professional photographer & I was looking same filter Ring Adapter & I order this product which is very helpful for me when I use multiple filter with my Nikon 5300 camera lens. During photo-shoot many time we have to change camera lens along with filter also, so using this ring it is very helpful for me, these rings get there job done, and don't get stuck. Please note - these are step-Up rings also have Step Down Rings total 18 rings.

Up and running in less than 5 mins. So easy to use.

It is a variable and polarizing ND filter.
The ND is 5 steps, there are 2 steps, 10 steps (ND1000, 1024 to be exact).
The polarizing filter eliminates light reflections on surfaces, cars, water, glass and also enhances the colors of the sky, leaves, asphalt, etc... (for more information search the web) Personally, I use it for video so as not to reduce the depth of field by closing

the Losing membrane (f9 further, I can now go to f2.3 without burning the frames from excess light). Haven't removed it from my 35mm in a while, I love it.

The filter is made of metal and glass, presented in a hard plastic case for storage. The protective and anti-glare layers of a greenish color are appreciated and you can put the lace on top that holds quite well without staining.
The lever changes the density of the filter and the other ring moves the polarizing filter. You need to pay attention because you can move both carefree.

In the pictures you can see the filter attached to an adapter, (Step-Up 49mm to 67mm) this is because I have filters of 67 and 49, my advice is to buy big filters and then "Step-Up" adapters.

About the picture quality. Excellent: There are no dominants, no chromatic aberration, no loss of definition, no appearance of the gradual ND filters' terrible X.
I have a very expensive polarizing filter and I hardly notice the difference with this one.

As a negative point, although I said before, be careful when handling one of the rings so as not to move the opposite.
