If you’re thinking about using this as a spotlight for your photography needs - grab it don’t wait
I will say though, it died at around 50 minutes and it was fully charged, it also gets VERY hot.
But it was very easy to use!
And the brightness was perfect and had different settings. Also the rubber band that goes around the light also is capable of making the light “smaller” or “larger”

The first thing I noticed about the K&F Concept SP25C is that this thing is hefty. The second thing I took note of is that the claim this is RGB is false. When you are using descriptions to make decisions on whether a piece if equipment is right for your application, you want that description to be accurate. It's not the only discrepancy: 70 minute operating time, metal magnetic GOBO filters, 10° spotlight to a wide 60° floodlight, included ball-head mount... these all either describe an alternate product or are remnants of a concepts features that didn't make to production and someone forgot to update the marketing kit.
This incredibly affordable, high quality device is a portable, 25W cylindrical projection light that is perfect for the budget conscious photographer / videographer. Highly versatile for its size, it's compact and easy to use in a variety of situations both in the studio and in the field, thanks to the dual rechargeable 4500 mAh batteries and the ability to use continuously while plugged in. It's a good, sturdy piece of equipment that feels very durable owing to it's aluminum alloy casing. It has a clean design with built-in heat vents and cooling fan, an included mount, two 1/4"-20 threaded mounting points, a USB-C port capable of 30W fast charging, and one-knob operation.
One-Knob operation is simple and intuitive. Pressing the knob for ~3 seconds will turn the spotlight on, while a quick press will alternate the four color chips (cool white, red, a very warm white, and blue). The four color selection can be limiting, but I actually appreciate being able to use this without need of an app or software. I mentioned before that this is not a RGB light despite being listed and advertised as such. You can't even rationalize it away as "available colors," as there isn't even a green light beyond the ring light that circles the control knob. Intensity is controlled by turning the knob, up to a brightness of ~1000 LUX. Focus adjustment is achieved by a sliding lens head, tough this feature feels a bit stiff and awkward and doesn't adjust the beam very much (~45° to ~55°).
While this can work as a key light, it seems better suited as back-lighting for a small studio or mood lighting. You get 20 85mm shape stencils, called GOBOs, three of which are uncut and ready for you to make your own, which are held by an attachable silicone holder. When using the GOBOs, the position of your projection will change position somewhat. This may not be a deal breaker, but it is something to take not of if you are particular about positioning as it will require adjustment. The projected image isn't very sharp but is good enough for small spaces or close placement to the wall.
As a great value light for smaller studios that aren't running 300w lighting, the SP25C does what it's intended to do and makes for good accent lighting.

This is a great light. I’ve considered buying a snoot many times, but this is far more portable and multi-purpose, so I’m pretty happy with that. It feels like a professional piece of photography gear.
You can turn the dial to make it brighter, and I think it gets quite bright. You can also pull the end out to decrease the diameter of the light, so you can get more light focused in an area if you like or soften it up for wider areas.
The main drawback is really only that it feels a little delicate and I worry about breaking it. But that’s like any photography gear I suppose. I like that it comes with so many different stencils too. I’ll probably only use the more popular ones, but the others will be fun to use on special occasions.

This is a specialized lighting device, used primarily for photography, but could also be used for scene lighting if powered continuously via the charging cable (supports up to 30 watt charging). It is a little unusual in that it is compact and battery operated. Think of it as a focused, high power flashlight with a choice of 4 colors and a hood that holds GOBO (goes between) disks of different designs to create shaped shadow patterns. The kit comes with a set of 20 black plastic GOBO disks, 17 of which are pre-cut with patterns (e.g. window frame, wings, text), and 3 of which are blank, to be cut with your own custom design (like a wedding greeting). They can be cut with a razor knife, or ideally with a laser for more intricate designs. Additional GOBOs can be made with black cardstock or plastic sheets. The end of the light cylinder slides in and out to narrow or widen the spotlight-like beam. A silicone hood slides onto the end of the light cylinder to hold the GOBO disk. The light is charged via a provided USB cable, but the USB power supply is not included. A standard threaded mount is included to attach the light to a camera tripod. It is fairly heavy (1.5 lbs) due to the battery, so it requires a stable tripod. A rotary knob on the side is the only control. To prevent accidental turn on, you must push the rotary knob in AND rotate it quickly to power up the light. Once on, the light intensity is adjusted by rotating the knob. There are no stops on the rotary knob. Once the max or minimum intensity setting is reached the light will flash. Pressing in on the knob repeatedly changes between the four color modes (cool white, warm white, light blue, light red). Holding the knob in turns off the light. The battery life depends on the brightness setting, but it is rated at 70 minutes at full power. There are four different LED chips behind the lens, one for each color, and the light is rated at 25 watts. The unit gets hot, and there is a cooling fan built into the light. The fan is pretty quiet and should not be a distraction. This is a spotlight that creates a circular light pattern with no GOBO disk in place. It is not optimized for broad area lighting, though it can be used to focus high intensity light on a subject within a scene. The light itself is very well made with a quality aluminum housing. The silicone GOBO hood is a little flimsy, and inserting the GOBO disks in this hood is a little awkward due to this flexibility. The disk fits in a groove inside the lip of the hood, which must be stretched over the disk. But it does work, and the design assures no light leakage around the edge of the disk. If you have not used a GOBO to create shadows in photography, you will find this greatly expands your creative options. It is compact enough to easily transport, and does the job of larger, heavier equipment. I also plan to use this for scene lighting (for indoor Halloween decorations) supplemented with a 40 watt charger.
