P.S. With, say, 10 x 20W CFLs on the circuit, even the cheapest models would
have a stab at.

i.e. APC ES350, 350VA/225W. (~60GBP)

With 10 x 100W conventional, you need 1000W.

i.e. APC Smart-UPS 1500VA/980W (~370GBP)

Will almost do it, if you swap one bulb for a 60W!

Alternatively, you might get away with a power conditioner, which is
basically a UPS without a big battery. You get no downtime protection, but
they might help with the flicker and maintain line voltage during a
brownout. They'll also get you longer bulb life if you have habitual
overvoltage on your line.

It's a very bad idea to run a UPS at or near full load. It will shorten the life time of the electronics. And if the load
increases slightly the UPS will switch off due to overload.
Also most UPSs won't help with light flicker (except true online double conversion) - see my earlier post in this thread.
