Now I know those cheap Chinese things are a waste of money apparently, but I thought I'd start there and bring in better ones if I got on with them.
I ordered some capsule bulbs off a Hong Kong ebay seller, but at the last minute decided to get 12 LED G4 bulbs instead of the 24 bulb model. I only spotted as I hit 'Buy' that the pic had changed to a flat bulb from the cylindrical one I planned to order, but... too late!
Anyway, they only took a week to get here, cost £9 for 6 bulbs, and although they only project light from one side they seem to not only do the job, but are very bright. The 'one side' thing doesn't seem to be an issue in this application with the swivel spotlights.
My primary reason for change over and above the power saving was a safety issue, my halogen G4's burn extremely hot and more than once i've found my bed pillow touching the bulb in the overcab! ...could be nasty. These LED ones are only just warm when on.
