thread I don't understand halogen bulbs
it's like someone took the basic concept of lightbulbs and then decided it'd be better if they had an average lifetime of a week, coupled with fittings that are almost impossible not to destroy when you try and replace the fuckers

I've got 4 such in the kitchen, I've literally gone through about 9 bulbs since we moved in at New Year, 3 are currently out cos I just can't be arsed any more

(although to pre-empt CI I'm guessing that the problem is probably dirt cheap transformers)
permalink GU9 is a horrible connection
GU10 is better but they are mains voltage so come with their own issues.
