I've a balcony which gets very little direct sunlight, and the back
gets pretty much none at all. I recently bought some plants and,
surprise surprise, those at the back aren't doing too well. I was
wondering whether I could substitute for the lack of sunlight by
installing a floodlight with a 4000K bulb (and have it switched on a
timer).

Google finds me zillions of websites selling "grow lights", which seem
designed for people growing pot in their basements, cost a fortune, and
look like they're supposed to be mounted right above the plants rather
than in the ceiling. Problem is that the balcony is about six foot by
six foot, with a nine foot high ceiling, and the floodlight would have
to be mounted in the middle of the ceiling.

Was wondering if anyone here knew if what I'm trying to do is remotely
achievable and, if so, whether there are any recommendations for
suitable lights/bulbs.

Somewhat offtopic, I know, but the pot-growing newsgroups all looked a
bit cultish for my taste...

thank you!
