If you're checking out the Godox SK400II-V studio strobe and want to know its power output, it's listed at 400Ws (watt-seconds) according to the manufacturer. This should give you plenty of light for a range of situations, like portraits or product photography.
Just a heads-up: this model doesn't have TTL (Through The Lens) capability, which means you'll be adjusting the flash manually without the automatic exposure settings some photographers like. But if you're someone who prefers to tweak settings yourself, this might not be a big deal.
One thing that's pretty neat about the SK400II-V is that it comes with the Godox 2.4G Wireless X system. This allows you to control flash power, the modeling lamp, and more from a distance, using triggers like the X1, XT16, or FT16.
From our research, this remote feature is pretty well-liked because it adds extra convenience, especially in studio settings.
The strobe offers 40 steps of power adjustment from 1/16 to full power (1/1), letting you fine-tune your lighting to get things just right. Plus, the LED modeling lamp helps with previewing lighting effects and is energy-efficient, so you won't drain your power supply too fast.
While the lack of TTL might push some photographers to look at other options, the SK400II-V is a good pick if you're okay with manual adjustments. It's got solid performance, and for a controlled studio environment, it delivers great value with its features.
If you're in a scenario where you need faster adaptive lighting, though, you might want to check out other Godox models that include TTL.
