So in a sense, I'd still like an option to mount it differently and more out of the way before splurging €1.2k + ~30% customs/VAT on something like this.
This even prompted me to check out comparable video fill lights on Aliexpress, and they also run around $1k (some at $500 with possibly a few gotchas about actual light output) for comparable luminosity/wattage, so your price is actually not too shabby.
