I’m just putting this page up here because I seem to need lots of these things. When I first moved into my house we had a lot of fittings for these GU10 – 220V bulbs. In particular the kitchen has 6 of these above the table and a further 8 in the rest of the room. Traditionally these bulbs are 25W which means we would be looking at a total power consumption of 350W, which is rather excessive. By replacing them all with these LED bulbs we are looking at a total of 32W. That is a considerable saving.
They do seem to come from China, so can take a week or so to arrive, but even so they are way cheaper than you can get in France.
