OK after giving this some consideration, I think the better option would be to go for these small Lumecube 2.0 lights.
As said it is especially for macro photography. I needed something small (so no big led panels) and directional (I am not a fan of too diffuse light when shooting macro - I have a ring strobe and don’t like it) and reasonable autonomy and high output (to be able to shoot with small apertures).
It was a bit simple, thinking I could do this with a couple of cheap flashlights.
OK I will keep you informed, I just ordered a Dual pack. But there are a lot of reviews and videos around about these lights.
There is an alternative that is nearly the same (Litra Torch) and a bit cheaper. https://litra.com/products/litratorch-2-0
Both have pros and cons.
A third alternative is the Mirfak Moin. Costs only half as much but some user reviews I read, did not convince me. https://www.mirfaklight.com/
Interesting thread. I just stumbled on it since the 3D I received seemed quite green. Still quite a deal, but definitely not as neutral as I’m used to. I’ll try it outside when it gets dark.
