In studio use, 300Ws is a substantial amount of power; during testing, the flash was typically run at around 200Ws, at which level recycle times were just under 1 second. At full power, recycles were comfortably under two seconds, which is more than fast enough to keep pace with a natural shooting rhythm.
Battery performance comfortably met and slightly exceeded Godox’s claim: a full-power endurance test reached 362 consistent exposures, while working at reduced power produced well in excess of 400 frames.
Another point here is that while many flash units of this size also give you the option to be mains powered for use in the studio, the AD300 Pro II is battery only, so an additional battery would be a good idea. In this test, around 400 shots per outing were more than enough, especially without the head being used at full power.
Through the test, I used a Sony A7 IV and Godox X3 Pro as the flash trigger, which enabled me to control the power and flash mode from the camera, and gave a good professional feel to the workflow.
One of the issues with some cheaper flashes in the past has been colour consistency; however, here that colour temperature did seem consistent, and for any pro, it will be one of the most important features.
Having allowed the unit to acclimatise to the studio environment and warmed the light through with a series of initial test frames, colour temperature remained stable throughout the session. For me, this is of particular importance, especially when shooting fashion or product for books, as you need that consistency of colour, and in the past, this meant the expense of a Profoto or Broncolor head.
TTL metering performed well in balanced studio conditions, though, as with any TTL system, scenes with complex or contrasty content required manual compensation. HSS functioned as expected, enabling synchronisation at shutter speeds up to 1/8000s.
Outdoors, 300Ws at close proximity is more than sufficient to make a visible impact on the scene, especially with the rather grey and overcast weather conditions that we have been experiencing so far in 2026. With these slightly subdued illuminations, the modelling lamp proved to be not only a reliable guide for lighting positioning before switching to flash, but also as a video light.
On the front holding the light modifiers to the flash is the Godox mount, which works well with native modifiers, and the optional Bowens adapter opens access to a wide range of third-party light shapers, though it is worth noting this is a separate purchase and not included in the box, which is a shame.
Ignoring the price, this flash is able to compete with some of the best on the market, and the build quality and durability have taken a massive leap forward. When you do start to consider the price, you realise what exceptional value this head is, and for someone who has, for the past five years, used Profoto lighting gear and the superb B10S, these units offer a very viable, cheaper alternative, and I can buy three for the price of one of the latest B20S.
