Our kitchen has under-cabinet lighting that uses halogen 20 watt G8 socket bulbs. With 15 bulbs in the kitchen that is 300 watts. I'd prefer to replace them with 3 watt LED bulbs.
I've been searching but I haven't found any 120 volt AC G8 LED bulbs that will work. The only ones that I can find are over-sized like this one. I wrapped one of my dead halogen bulbs in newspaper strips until it was 1.25" in diameter like the over-sized bulb and tested it. It wouldn't fit in the light fixture.
Do I need to replace all the fixtures? There seem to be a lot of G4 LED bulbs on the market, but very few G8 bulbs.

Your G8s are probably 120VAC, right ? As such, you are not going to replace with LED without switching to LOW DC voltage. Most are 24V.
If you want dimmable LED (a good feature), you'll need a dimmable constant current driver and a magnetic transformer and a magnetic rated dimmer. You can use a standard dimmer, but the current surge will burn it out. (ask me why I know...)
Bottom line.. rip out the sockets.
