GU10 LED bulbs (Formby Village)

I have a number of GU10 LED small spotlight style bulbs that are surplus following the replacement of some lights.

There are (roughly) two sets of 10, one set rated at 6.3W and the other set rated at 3.6W, plus a few other IKEA ones rated at 4W. (The IKEA ones have the slightly protruding lens as seen in the picture, all the others are the flat style).
