A couple of years ago, I was nearly ready to part with about four hundred quid for a decent floor-mounted reading lamp from Serious Readers, as advertised in all sorts of glossy publications aimed at the (ahem) "third age" market. (https://www.seriousreaders.com/) To cut a long story short, I ended up with one of these swan-neck LED things from Amazon: https://www.amazon.co.uk/dp/B07CZCVFLC/. Currently £42, but I think I paid about £25 at the time, before the Chinese renminbi started getting more expensive.
Flipping heck! Five different Kelvins, five light levels, and a remote control in case I change my mind about those 25 options after I've already sat down.

There seem to be loads of Chinese firms running exactly the same product under different names. Shop around. Not bad at all.
