I would try different wattages of Compact Flourescent - cheaper I believe than the type of Dimmer that would be needed.
Compact flourescents come in different wattages and different colours - makes a huge difference. I purchased 13watt CFLs in colour temperature s of 2700K (warm white) and 6400K (cool daylight). In our kitchen the 6400K give the sort of task light that we want. The 2700K seem much dimmer and we find unacceptable in our kitchen. We had to search a bit for 13watt - more common are lower wattages - starts at 7w.
I bought from here if you Google "liteworksuk.co.uk/replacement-lamps/mains-voltage-spotlight-lamps/energy-saving-gu10-lamp.html" . Good prices and range. I can't comment on quality / life as I only did this a few weeks ago.
Sorry - can't make the link work - any hints appreciated
