Through the test,, I tried out a variety of lighting scenarios, from interviews to still life, and even at direct-to-camera pieces. Through the test, I found that around the 30% brightbess at 1.5-2m was the best range and gave the light enough room to offer a decent spread of light.
I also found that the small, thin honeycomb filter had quite a dramatic effect on the spread of light, so if you want a more contrasty effect, then leave the grid in place, softer than just using the diffuser.
I started with some basic tests to just see how the light performed when it came to endurance, starting with setting the light to 100% brightnesssee how long it would last. The M60 Ultra lasted 28 minutes on a full charge in a timed test, which is not bad, but far from a full day’s shoot.
In practice, 28 minutes is limiting as a standalone battery-powered main light at full power, though it comfortably covers most interview setups. At 30% brightness, the runtime extended well beyond an hour, and 30% is more than sufficient to illuminate a subject at 1.5–2m, which is what I found was more realistic when I started to use this as part of my main kit on a couple of shoots.
I did, however, find a solution, and during a test shoot, I found that running the light from a USB-C power source was an ideal solution. As I had the BLUETTI Elite 300 in for review at the same time, I connected this via USB-C, and the M60 Ultra ran continuously between takes. Pass-through charging while the light is in use also worked without issue. Obviously, a smaller station could be used, with the max input being 17W, and using a smaller powerbank, it topped out at 6W.
The fan noise was surprisingly good or low, which, with the large fan on the back, I wasn’t expecting. It’s actually the quietest light at this power level and form factor I have used. In interview situations, the fan is not a concern for audio; it sits comfortably below the threshold where it would be picked up by a directional microphone at a normal interview distance.
Heat was kept in check, and I found that after 30–40 minutes at full power, the body is warm but still handleable. The front panel gets hot without the diffuser, as expected , but with the diffuser fitted, the working temperature is manageable.
