It is a decorative light fixture, so the lighting, as expected, is not very strong.
However, it is impressive, as well as how you can adjust it with the TNT piece.
It is only USB powered, it does not accept batteries!
After I opened it and did not find space for batteries, I confirmed it by carefully looking at the box and finding a more accurate description of it on a foreign site.
So the description is wrong, as well as the evaluation for the batteries. At least in the version I bought.
