Successful replacement

I have replaced with these lamps -12 Pieces my previous 10 halogen lamps. I'm with the luminosity more than satisfied. The lights I installed in a wooden ceiling in the hallway. Make Me is a beautiful picture. They can also be swiveled. I wonder why I did not replace the halogen lamps for a long time. Previously 10x 50 Watt = 500 Watt and 60 Watt now. The lamp is also dimmable eighth -When buying it, if needed, as it they also "non-dimmable" are. Also note, that not every dimmer is suitable.
