Certainly, the diamension will be much bigger than a MR11 bulb, it need a
ballast so it is much bigger thana normall bulb, but the lumen efficiency of
engery saving lamp is batter than halogen bulb ( about 4 times ), I remember
MR11 is G6.3 base not GU4.

MR11s use GU4 bases. MR16s use, IIRC, GU5.3. Some low voltage halogen
capsules use G6.5. I have no idea what, if anything, uses a G6.3.
