Very consistent, and the slight change in decimal point is more likely down to the subtle movement of the meter during the test. Pretty much bang on. I'm under the impression you aren't a working pro. There's no getting through to you, so I'll post for the people who read this so they won't get swayed by your misinformation. Overall, the AD400Pro and AD600Pro are both amazing portable flashes that perform very well in both indoor and outdoor settings. So Flashpoint are currently lookinginto different 7″ reflector options that may suit the 600 PRO better. Godox 600 Pro all-in-one outdoor flash has stable color temperature (variations within ± 75K full range of power in color temperature mode), you can maintain accurate color temperature even at full power; Small, Light Weight and Portable.

The flash head itself has had a bit of a redesign, with a little extra added sleekness. It now has cleaner, rounder curves, with an easier to see read button layout. You’ll note that while both strobes are Bowens S-Fit, the new design features a new style of reflector. And inside that reflector is a newly designed bulb & fixture design, too. It’s been speculated, although we won’t know until we can get one in our hands, that this adds potentially up to a stop of output due to better efficiency. The controls are familiar. But the innovation is outstanding. News breaking features like: recycling in under a second at full power, super stable color output, real modeling light power from an LED, and integrated reflector while maintain the classic Bowens mount, and superior flashtube performance.

Transmitters

The colour consistency is now matched by other Off-Camera Flash (OCF) units, such as Elinchrom with their ELB 500 TTL, which I reviewed previously HERE. 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 shot. These are all worthwhile improvements but if you don't benefit from them then good news you get to save half your money, you win either way. The Flashpoint XPLOR 600PRO is a solid contender for the higher priced flash models. The upper echelons still have name recognition, brand trust, and in Profoto’s case, rental house ubiquity, but Flashpoint is definitely making a splash with this strobe. It takes a leap of faith to take a budget-priced strobe on an important shoot, but I did it and survived to tell the story – and it’s a victorious one. New power button sequence prevents accidentally turning it on and wasting power (or burning anything) while travelling to or from a shoot

A major feature of theGodox X / Flashpoint R2 Systemhas become the cross platform support forCanon, Nikon, Sony, Fuji, Olympus / Panasonic, Pentax, and Leicacamera systems, supporting both TTL and HSS. But regardless of whether we were shooting within sync or at 1/1000th of a second, the AD400 Pro never missed a beat. Of course, most of us wouldn’t expect it to, but this is possibly the first time that anybody has tried it on a Pentax camera outside of the Godox test labs. The Godox AD range of flash heads is by far the most popular of the Godox flash series and for good reason! Every light is powerful, portable, lightweight and exceptionally high quality, so it's no wonder that photographers are all looking to expand their kit using these lighting solutions. However, a few of the questions we often get asked are, what exactly is the difference between the lights in this series, what can each power level of the AD range get you, and which modifiers will these lights work with? To answer these questions, and more, we have created a comprehensive guide to buying your Godox AD flash head!

Cons

This XPLOR 600Pro TTL can be linked and synced to be triggered wirelessly in complete TTL operation with any R2 transmitting member of the R2 Family: The prodigious Flashpoint models of Streaklight 360, Zoom Speedlights, R2T and R2Pro Remote Transmitters - all work seamlessly to clear the path onto the challenge of mastering the light, wherever you go. Absorb it well, and the mighty lighting tool you have before you will become a beacon of power in your arsenal of creative photography. In summary, though, it feels like a good solid light, and it seems to have all the features that were added to the AD600 Pro in a recent firmware. The first XPLOR600 proved the power of R2 to master the light wirelessly, and now, the XPLOR 600Pro goes beyond, with sleek design, practical control consolidation and keen responsiveness. True accurate TTL, lithium powered mobile imaging that spurs your creative imagination to conquer distant vistas, solve the challenging lighting situation in any environment, adapt to multiple camera systems right out of the box.

My idea would be to have 1 Pro as the main light where even in a box at 12 feet you could get f8 to f11 on full and still keep 1 sec recycle. Then a couple of the less expensive versions for the other bits where at lower power outputs they will keep up easily.COMPLETE COMPATIBILITY - The Godox AD600 Pro is completely compatible with major camera brands. With full TTL connectivity for Canon E-TTL II, Nikon i-TTL autoflash, Sony, Fujifilm, Olympus and Panasonic TTL autoflash systems, the AD600 Pro also has full support for 1/8000s High-Speed Sync for compatible cameras But the AD400 Pro proved to us that it could handle the vast majority of situations any of us would find ourselves in for both our personal and paid photography work.

CRI readings (Ra) are mostly around 97.6, andaslightGreen tint is starting to show around 1/16 and 1/32 power. The AD600 Pro also offers a very powerful modeling lamp, meaning that this light can also be used as a video light alongside its flash capabilities! Offering a 38w light, as well as a 4-hour battery life from a single charge, the AD600 Pro is a great tool for both videography and flash photography.Ok, so maybe Paul asked me to add that last one. I’m curious to see what will happen, actually, with 3rd party flash support with Sigma’s new Panasonic/Leica alliance. Wow! 13 kelvin short of hitting the nail on the head. Now that's 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. Whilst the AD600 Pro is a wireless flash, powered by rechargeable Li-ion Batteries, an AC adapter is available to create a mains-powered flash head. This AC adapter is great for studio work as it means that neither you nor your work is restricted by battery power on longer shoots. By offering the choice between mains or battery-powered, the AD600 Pro becomes an even more versatile, lighting option for all shoots! TT600 and V850II: Full-size speedlights with no TTL, and are only HSS capable when used off camera. Again, the TT600 uses AA batteries while the V850II uses a lithium-ion battery for faster recycle times.
