In my search for a replacement for the still "energy-guzzling" Halogen lamps GU-10 I've tried this. Good bright light, slightly whiter than halogen but quite pleasant and well ausleuchtend. Small drawback when used with dimmers; Lamp was in the dimming almost imperceptibly darker until shortly before the extinction; So m. Not recommended for E. "soft light switching" in the nursery or similar spaces; then prefer to use non-dimmable and buy a slightly more favorable light without Dimmmöglichkeit.
