The SmallRig RM75 video light is actually quite small. At 9.9 x 6.7 x 0.18 centimetres, it will not take up much space in your camera bag. Despite the small form factor, it delivers a CRI at 96 and a colour temperature in the range of 2500K to 8500K.
It is powered with a 4Ah battery, which I find to be a large battery especially considering the small size of the light. The spec sheet promises 3 hours of operation at full throttle, and if you ask me, that is a mind blowing performance! When I think back just a few years what a small LED light could deliver, then giant steps of progress have been made here!
The box with the light contains very little other than the light: a manual, a user guide, a USB cable and a light diffuser.
I must admit that I thought the light diffuser was a case to protect the light mainly, but when I tried to fit the silicone rubber case, I could see that the case is somewhat thicker than the light itself. This design to create a space between the light and the case, so the heat can dissipate. That said, the diffuser will also protect the light, the same way you probably have a cover for your smartphone.
I enjoy USB-C charging very much! It saves me from unboxing yet another charger, and it also means that I can charge the SmallRig when on the go, say via my power bank or the USB plug in my car. So USB-C charging is very welcome! And I am also glad to see that the SmallRig charges with a powerful 65W charger – not all devices can stomach so much power (for the tech savvy: it supports USB-C PD).
In use
There are not many buttons on the SmallRig and that is good news if you ask me! Other than the on-off switch and the USB-C connector, there is only a command wheel to control the light (it is named “SET”). It works simple and smart: push it once to enter/jump a menu, and long push it to exit the menu. Turn the wheel to change the value, say the strength of the light or the color temperature. The menus and options are displayed in a small OLED screen on the middle of the rear of the SmallRig light.
There are 3 main menus in the menu system and you can control all aspects of the light (light intensity, color temperature, saturation, hue, etc). There are also a number of predefined effects that you can choose between like fireworks and a police car. For my liking, it gets a little bit fiddly to choose between all those options with just a command wheel, and luckily there are 2 QR codes in the manual – one for OIS and one for Google. In other words: the SmartRig has an app! Everything seems to have an app this day and age!
The app is maybe not the most elegant software I have come across, but it certainly gets the job done, and it also secured that the software in the SmallRig was updated to the latest version, before I started to use the app in more detail. For my usage the most important is to be able to control the intensity of the light and the color temperature – and sometimes also to turn the light on and off remotely. So I have not deep dived into the more advanced functions, but it sure looks overwhelming with all the effects that are available and the way you can tweak the hue of the light.
Mount
There is a small 1/4″ thread in the bottom of the SmallRig so you can mount it on a tripod or a boom arm or whatever is to your liking.
As a new feature (at least for me), the SmallRig also has some magnets that makes it possible for you mount the light on a metal surface.
I found the magnets to be relatively weak when holding the 185 grams light, but if you find some metal that is sufficiently “beefy” and flat, then it definitely works.
Conclusion
The SmallRig RM75 here in late 2022 retails for around 80 USD which I think is a very fair price for a powerful light with lots of features and controls and a battery that will keep you with light for several hours on one charge.
The question is if the 5W of light the SmallRig yields (500 lux at 0.5m) is sufficient for you and if the surface of the light is big enough for your needs. That comes down to exactly what your needs are for lightning. But if you find that the size and the illuminance of the SmallRig will cover your needs, then I have no hesitation to recommend the SmallRig RM75.
