I performed a REAL World test of the Neo 2 after doing the power tests and found it to actually be a useful product for different types of photography.
Please check the thread here so you can make a much better evaluation of the product real life performance and determine if it works for you or not.
I ended up getting 2 of them.
So please check the follow up review here which I feel is a much more fair evaluation of the product capabilities and will let you decided if it is a product for you or not.
So I will be returning it soon since to me, it is extremely underpowered for my needs but just wondering if you guys want to see any particular tests with the Neo 2.
I have the eVOLV 200 and Xplor600 as well. I also have a Sekonic 858D in case you want some tests like that.
Maybe if I did more indoor/night stuff, it would be a better fit but for my regular work, I dont see how this light can work for me. I love underexposing backgrounds for my looks and with this thing I dont think I can even expose it correctly during anything but sunset or night shots.
No wonder lately all Jason Lanier does is indoor and night shoots..and even then he ends up increasing ISO often.
Updating with results of comparison vs Godox AD200:
Dark room with light meter at 6', 1/50, ISO 100.
The AD200 gave me F9 with bare bulb and F11 when using the back plate "mod".
The Neo 2 gave me F1.3 with batteries and F1.6 connected to the AC which gives an option of MAX+ for the flash.
Second Test results:
I decided to try another test this time using the Godox Ving V860II (the adorama rebranded one) vs the Neo 2.
Since the usual comment from the Rotolight rep when someone asks about the Neo 2 power vs a speedlight is that you need to diffuse the other flashes and lose a lot of power vs the Neo 2...I decided to put those claims to test.
To give the Neo2 all the advantage I decided to not use any modifiders with the Neo 2.
For the Godox I used a Mola Setti (White) in 3 configurations: with the mesh and the opal stack, adding the sock diffuser to those and finally without the sock diffuser but placing a solid metal beauty dish plate from my 56" Fotodiox beauty dish so that it was mesh+opal+fotodiox plate.
Settings were as before with light meter at 6', 1/50, ISO 100. The Godox was set to 24mm. The Neo 2 was set to its brightest temp 4110 and MAX+ as it was AC powered.
Neo 2 Results:
Once again it got F/1.6 at Max+ flash power at 1/50 (changes to 1/100?)
At MAX Constant light it did F/1.0
Mesh+Opal+Sock diffuser: F/5.0
Mesh+Opal+Fotodiox Metal plate: F/4.5
So much for the claims that because of all the diffusers needed to make the speedlight soft, the power differences were not as big as some may think. And to clarify, I personally would still use a diffuser with the Neo2 for softness but as you can see, even without one it is extremely weak.
If this was Mythbusters I would end with a...."BUSTED!"
Here is the video of the test:
I did a quick test (not on this video ) with HSS:
Godox at full power with the Mola Setti using mesh+opal = F/1.4 Shutter speed 1/2500 ISO 100
Neo 2 with no diffuser, temp 4110 for max output and with AC adapter. With Flash it got F/.8 and with 100 constant light .5
