You have to cut back anyway, the two contact pins that are lagging considerably too long, but afterwards you can see the glasses of the spots no longer fit or close. The light is not directly 3000k thermal insulation, rather "ledwarmweiss".
The brightness is very good, which (are possible) 1 Watt G4 from Ikea, which I had also tried unfortunately are just too dark.
So I will therefore continue to search ...
Because of the large size to the LEDs are not recommended.
