I really like this photographer
Achim Kluck
And I noticed that he has something novel a smart phone led on his lens. I think the idea is so that you can get lots of photos to stack so you don't need to wait for flashes to charge

Can't seem to see the shutter speed he is getting, lighting looks good though.

Nothing inherently wrong with LED lighting provided you can get good color cast (some light sources just can't be "fixed in post"). The down side to it is, with current tech, you won't be able to freeze motion with it. But since he's focus stacking he's not shooting moving subjects. One word of caution: Vibration due to mirror slap could be a problem with LED lighting...

If he is just stacking dead subjects in the studio then almost any light source will be Ok as long as all is solidly mounted and as noted mirror lockup is used.

I don't know what the spectral characteristics of white LEDs is, I guess it is not remotely black body like.

It makes sense that he is stacking because usually LED lights are just not bright enough to take single shots with a high f stop, so he would be taking lots of shots at probably f/2.8 which give a very shallow dof but bright enough images to stack. I also noticed that he has done some 4k stacks, these are quite popular and easy to do but usually not as detailed because the ISO is usually higher and a 4k image isn't that high resolution.

I use LED panels for stacking in the studio, bigger than those ones so they are self diffusing and they have a corrected colour balance but, when you start getting to high magnifications it is troublesome stopping vibrations, even with mirror lock up on, which is why flash is prefered.
