Two of the halogens have failed. First time I've had to replace any of 'em since we moved in.
There's a cupboard full of various CFL and LED GU10-equivs. Do any of 'em bloody fit? No, of course they don't. The CFLs are laughably huge, total non-starter. But the LEDs look like they should... Oh, wait a second... They curve slightly out from the edge, so the sodding retaining clip won't _quite_ fit.
Why is this not easy? The GU10 halogen package is not exactly news to bulb makers. It's been around for years. It's _prime_ for replacement with lower power equivalents. So why...?
