We bought these LED-filament candles as a substitute for normal 25-watt bulbs in our chandelier. From the optics, the LEDs are very nice to look at, though differently than incandescent bulbs, but really no worse. But above all, the tremendous energy savings makes the big difference for us. The specified Entprechung to 20-25 watt bulbs is alright, besides a Direction powered by a 25 watt light bulb lit both about the same brightness.
Small point of criticism: In rapid eye movements and the LED-filament candles as the only lighting in the room a slight flicker is noticeable. My wife does not see but I feel it is not disturbing.
Given the truly beautiful appearance and the enormous energy savings we can only recommend the LEDs.
