So, wandering round Asda yesterday in the quest for cheap olives I discovered something I really didn't want to know. Not only are there lightbulbs with standard bayonet fittings, lightbulbs with small bayonet fittings, those with standard Edison screws and those with small Edison screws, it turns out that there's (at least) a fifth standard - 4 pins.
Meanwhile, I still can't find an energy saving bulb with oomph greater than "100W equivalent", nor can I find anything over "40 W equivalent" with an SES. In Vienna, domm had something >100"W", so they are made, but he'd said that he'd had to go hunting around to find it.
Meanwhile, the cheapest energy saving bulbs in Asda were at 4 for a pound. Is this a loss leader? Is someone subsidising it? Please can I have LED bulbs before we all get mercury posioning?
