The above couple paragraphs were essentially a rundown of my thinking as I was testing. I REALLY wanted these lights to work. So, having decided that maybe I could live with using one or two power settings and modifying the lights with gels, I decided to test the color consistency between shots. This is crucial now. If the consistency between shots at say 1/8th or 1/16th is not good enough then the lights would be completely useless for freezing motion.
To test this, I took 10 shots of the gray card at each power setting, then color corrected the ten shots. The range was calculated by subtracting the largest result with the smallest, simple. As you’ll note the results were very respectable up until 1/32nd where everything completely fell apart. I was recording Kelvin shifts of over 1100K between photos! I got a pretty stable result at 1/128th power but the exposure varied by over 1 stop and hence was completely useless.
Final Thoughts – Is the Godox QT600II A Worthwhile Purchase?
I am currently on the hunt for the best studio lights within my budget which can freeze action. As such, the results of this test were important to me, and I am very sad to say that I cannot get behind the Godox QT600II. The color consistency in SPEED mode across the entire power range was so bad that you would be limited to using only one power setting, 1/16th and below. Granted, my results for the Godox in COLOUR mode were far far better, excellent in fact, but the whole point of this is to bring action stopping flash durations within a reasonable budget.
One Godox studio light currently costs £450. When you consider that (in the UK) one could import Einstein’s for roughly £560 each the argument for these lights becomes almost pointless. Having to only work with one power setting in SPEED mode is a massive inconvenience. Not only that but the Einsteins have a better color consistency across their entire power range. I honestly wish it were not the case, but I can in no way recommend these lights.
What about the Lencarta Superfast series? This one is a little tricky. Given the reports of users on Photigy I can say that they are adequate to freeze action. From my tests, while not being able to give a precise figure I can say that the minimum flash duration is above 1/8000th. However, I have also heard negative reports concerning the power consistency which I can unfortunately also confirm. I did not go to the same, table creating, lengths as I did for the Godox QT600II but I took many test shots and saw quite big fluctuations between pops.
In summary, if you need studio lights with action stopping flash durations and respectable color consistency at a reasonable price. The Paul C Buff Einstein’s are still king of the hill. On the other hand, if you can live without 1/10th stop adjustments, something I cannot, then perhaps take a look at the Godox AD600.
If you’re interested in learning product photography, then be sure to check out all of the education on offer in the Photigy store. The courses can take you from product photography amateur to pro, take a look here. If you have the budget, I fully recommend either a Pro club or Studio basics membership. Both are excellent options for those serious about product photography.
