Even with the little brother who 3.5W 60 SMD LED GU10 of sebson (280lm, 120 ° coverage), we are more than satisfied (ten pieces are currently in use in various places in the house), but we have due to the very good experience a few more copies of the 420 lm GU10 spotlight indulged. These replace the previously used now easily 50W halogen spotlights exterior (roof overhang)! The beam angle of 110 ° is also perfect for this application.
For indoor use, these emitters are we even too bright, hard to believe, when I think of the many tested in recent years "Funzeln". We have a total of 19 GU 10 spotlights in use in the roof overhang would correspond to the power savings versus halogen solely incredible 855 watts (950-95 W). I call that real progress !!!
The E14 48 LED bulbs are the way better, here we have 120 W (3 x 40 W bulb) replaced by 9 W.
