In my lounge I have two light fittings, both with three globes. These seem to go out with annoying regularity. Last time, I bought some long-life low watt bulbs and put these into one of the light fittings, sticking with normal bulbs in the other fitting. This was, oh, maybe as long as four months ago. The normal bulbs are still going strong and the long-life ones just died, all within two days of each other. So, since the long-life ones are approximately 10 times the cost of the other ones, I guess I'm back to buying the old sort again. Strange, and annoying. Meanwhile, until I get to buying some more, I sit here half in the dark typing this.
