Okay, so I know the Godox AD600 Pro and it’s variants have been around for quite a while. ( It became available at the beginning of 2018), and it was certainly a highly anticipated bit of kit. When it was announced, there were a number of key features that caught my eye, such as the 0.9sec recycle time at full power output, new bulb design and dome, better bulb positioning, flash duration indication, colour consistency and more.
Four years on, and how is it holding up?
Lets just take a quick look at the head itself.
I always rather liked the original AD600 incarnation (launched two years earlier), although I did find the stand locking mechanism a bit clunky due to the ratchet like system. That had been replaced with a none ratchet system that is smooth as silk, and locks very quickly and solidly. The overall look and feel is best described as “slick”, and somewhat reminiscent of the last Bowens lights to be manufactured, the X series. Well, if you squint a bit.
It feels incredibly solid, and the standard reflector feels like an integral part when fitted. It doubles as a tube protector when the protective cap is fitted to the reflector. I found that to be a nice touch, as I would no longer have to take a cap and a standard reflector on location. Less space and weight is always good. Talking about the bulb, with the dome in place, it does look kinda mahoosiv! But looking at it carefully, the frosting is applied to the front flat face of the dome, which definitely helps with the light dispersion from the tube coils when compared with the original. The dome seems to fill the standard reflector, and your eye is soon drawn to the rather large yellow circle behind the flash tube. A 38w LED modelling light. As modelling lights go, it’s damned bright! It’s much brighter than a lot of my standard studio heads, so it has real world application, as opposed to a number of modelling lights found on some location heads. It can be set to a pre-set level, or vary according to the power output of the head.
The one thing I found a little awkward when it was first released, was the fact there was no handle, so it tended to be a two handed affair when handling the head, such as fitting it to a larger softbox etc. Now we have an optional handle available, that bolts on to the underneath of the head at the rear. The lack of a handle was a definite downside on the original AD600, and something I regularly lamented at the time.
Now, as a commercial photographer, I tended to stay away from IGBT lights for the more colour sensitive work, basically because they drift towards blue as they are turned down. Some heads are worse than others, and if you mix IGBT heads with voltage controlled heads, you can see the colour difference, sometimes quite dramatically.
So, the colour accuracy mode that featured quite heavily in their launch press release, was something that piqued my interest, to say the least.
According to the specs, in standard mode, the colour temperature is only supposed to fluctuate by +/-200k from the stated 5600k. Yeah, I kinda smirk to myself when I read that, because, at the time of the launch, every manufacturer tended to state the same, come what may. However, I will come back to that later.
I had a Sekonic Spectromaster C-700 colour meter to hand. Well, to be more accurate, Marcin Wozniak had the meter with him when he brought the light for review. We used both the standard reflector, and one of the studio softboxes to check the output, bearing in ]mind an ageing silk on a softbox can warm the light.
With the standard reflector fitted, and the power dialled down to the lowest output possible, which is 1/256th and in standard mode, the colour meter gave us a reading of 5759k, which is definitely within the promised +/-200k of the stated 5600k. Bearing in mind what I said earlier, I have to admit I was quite impressed even with the standard colour mode. Particularly when the light has been dialled down to minimum, which is where the greatest variance tends to occur.
Switching to the colour consistency mode and re-testing, the meter gave us a reading of 5587k.
Damn! 13K short of hitting the nail on the head. Now that’s pretty impressive.
And using the softbox gave us 6076k in colour consistency mode, and 6134k in standard mode, so my softbox was about 500k out. I’m not that surprised, but it wasn’t a particularly cheap box 🙁
But what does it actually mean?
The first image is using colour consistency, whereas the second image is using standard mode. There is a very subtle blue shift on the pillow with the AD600 Pro frame left. There are two voltage controlled heads in use, one frame right and also frame top. I have to hold my hand up, and point out that this is actually a very small shift to blue compared to a number of other IGBT based heads I had used prior to the launch of the AD600 Pro, and I was very impressed with the colour consistency, even in standard mode. I did wonder if using the colour consistency mode made any difference to the recycle time. Nope. It still nailed around 0.9sec at full whack.
So, what about output accuracy when changing power output levels?
Using the standard reflector, and a Polaris Karat lightmeter (Yes, Mr. Wosniak’s again), placed thirty inches from the front of the reflector, I recorded the following results with the meter set to a sensitivity of ISO200:
Very consistent, and the slight change in decimal point is more likely down to subtle movement of the meter during the test. Pretty much bang on.
I did wonder if the HSS mode would be an issue with the colour temperature, because when HSS is selected, it automatically disables the Colour Consistency mode. At full power output with the standard reflector and in HSS, we recorded 5627k, and at 1/256th output, we recorded 5696k. Personally, I found that very impressive.
The last thing to do was to basically shove someone in front of the light and see what sort of a job it does with skin tones. Meet Marcin Wozniak, reluctant model.

In conclusion, I found I had a light that delivered exactly as promised, and outperformed an awful lot of the also rans, particularly those that promised the old +/-200k consistency rubbish. Even in HSS the accuracy was there. I loved the aesthetics, the recycle time, the displayed light duration, the LED modelling light, the menu system and far more than I can actually recall.
So, those were my thoughts at the launch of the D600 Pro. How has it held up in the four years since?
The colour consistency is now matched by other manufacturers, such as Elinchrom with their ELB500, which I reviewed previously. I have to say, the AD600 Pro has stood the test of time extremely well. I used it in various scenarios such as the following product shoots.
Textiles are a good litmus test for colour consistency, mainly because textile clients will know if their product is correctly coloured, or not. And they can spot a 100k difference a mile off, I kid you not!
And it was a textile shoot that showed up a bit of a challenge for my style of shooting.
For this image of a bolt of cloth, I had a large overhead softbox, and then a large gridded reflector frame right. The issue I had, was down to the weight of the head, which meant I had to counterbalance with a sandbag etc. and I still felt a little uneasy working below it.
I ended up swapping out the overhead light for an ELB500, which weighs little more than a gasp of air, and the AD600 Pro was used for the accent light. Now bear in mind, this is my personal choice, because I’m lugging kit all over the country most days of the week, and a lot of my shoots end up requiring overhead lighting, such as food etc.
And I have to say, the weight was the only negative aspect I found with the kit. Although the weight isn’t particularly heavy at 3Kg, taking four or five on a location shoot could be tiresome. And you also have to take 3Kg of ballast to counter weight the boom arm too.
Where the head is simply sat on top of a lightstand, it was fine, and gave excellent results every time.
I certainly have a great deal of respect for the AD600 Pro. It set the bar when it was launched, and it’s still holding its own admirably.
