Unfortunately, China scrap ....

These lamps are not suitable for my application.
The genes being 5 W LED are to be compared in any way with brands LEDs (Philips, Samsung or Toshiba) the same power.
The luminosity is significantly lower and (but in my eyes too garish "warm white" for) the light color is just about acceptable colors are pale and sallow.
I appreciate the color temperature to about 3000-3500K, which indeed goes through nochals warm white on paper.

After negative "aha-effect" wanted to send back the goods, but that would mean "back to China" with refund after X weeks and probably just as many mails. This effort is too stupid.
The seller has offered a 10% discount, but not much of help, if you need the goods can not.

I'll stop at the next purchase better eyes open where the goods come from.
This purchase you have unfortunately depreciate as "experience value".
