The problem comes with the GU10 CFL that are the same size as downlights. Due to the very small size you just don't get the efficiency needed. So you end up needing, as chuth mentioned, three times as many lights. If you want the best energy efficient option available today, nothing beats a 15W CFL in a larger than GU10 size. These are one-for-one replacement for halogen downlights. That is, you'll need one for every 4 square metres of floor space (4 for a 4 x 4 m room).
