I had the following concerns when purchase: erstahlt 1. The scattering angle is too small, and only the ceiling nice. 2. real dimming. 3. Color rendering
I am thrilled with this LED. All my concerns were unfounded. The lamp gives a nice, comfortable, cozy light again. I can sit and read to the coach under the lamp. The scattering angle is as good as before with the light bulb. Certainly, this lamp is not as bright as a 60 watt bulb. That was clear to me before you buy. This is not possible with 470 lumens. But you definitely replaced without problems a 40 watt bulb (rather even a little more) and is just right for my needs.
Many providers I had read about a humming noise ducks in the dimming and was therefore particularly critical when dimming. But even here there is nothing to complain about. The LED can be easily dimmed progressively (as with the light bulb also) and it is noiseless. My sense is that it turns a little bit later than the light bulb. I mean, in the lowest part of dimming the LED is dark. The bulb would probably have been even a dull flickering light. I find but not particularly disturbing.
We have this now LED for a 1/2 year in operation and are very satisfied. I recommend it more definitely, because in addition to good performance is also good value for money.
