IME the Philips 'professional' ones (PLET range[1]) are excellent. The
local John Lewis used to sell them but alas they only seem to carry the
subsidised stuff now. The better lamps do cost a bit more, but lamp
cost is down in the noise once you factor in the lifetime electricity cost.

Try something decent like Osram, using 23w for 100w, 15w for 60w, and
11w for 40w.

Agreed - Osram 'Dulux' types are also very good and 4:1 ratio is about
right.
