The good ...

Is favorable.
The light of this and the cool white (both for testing the same day ordered) are top.
Even after 2 months still flicker no failures or, as with other LED models.
Is not warm.
Fits perfectly into the mount, what is of low Spot LEDs also can not always be expected.
Beam angle is very large, not a SPOT.
Not dazzle as well distributed through the diffuser.

The only disadvantage, something disturbs the radio, I test the time now with ferrite cores.

Addendum: I now have a total of 7 of the daylight and 7 of the warm white. None of them shows any abnormalities and all of the same model and make the same light and have the same dimensions. Since I've already real experiences with others so cheap lamps.

I have paid the 6.50 per piece. that's okay! I see here but already partly call now some retailers twice. That's no longer okay!
