very puzzled, went to a friends house last night, and 2 of their bulbs had blown, when i asked where the spares were, they said that they have to order them off the internet as they are 3prong bayonet fittings, as its a new build house (about 5yrs old i think) - given all the new houses being built, you would have thought tesco and such would be teeming with them - but i have never heard of them, is there a chance this could be a load of bull, and would their be any harm in swapping the pendant light fitting back to "normal bayonet" fittings so they can use the normal stick low energy bulbs ??
