The LED bulb replaces a 60W incandescent bulb with us. Overall, the luminance distribution due to design more downwards, but this is not a disadvantage. On the contrary: The 6W LED bulb appear even brighter in this way, than 60 W.
No delay, no flickering. Nothing. So I imagine the replacement of an old light bulb.
Strong buy recommendation. Beautiful shape, timeless and elegant.
