1. The bulbs are quite a bit in direct comparison darker than the previous 20W halogen capsule lamps. At the above-mentioned bathroom lamp with only 3 pieces more LEDs similar type not get the sebson LEDs far off!
2. Three of the four ordered lamps have an unpleasant greenish line. Thus, the food and objects look totally unnatural. These three are also darker than the one that is still quite pleasant color and a little brighter.
3. Although an electronic transformer is used which is suitable for the performance of the four lamps, these flicker constantly light, which is unpleasant in the long run.
I guess no-name LEDs are used in the Far East and thus may occur quality, brightness and color variations.
It will probably not be long before at the same price brand goods with Philips, Osram, Nichia-, Samsung, Seoul- or Cree LEDs offered. I will definitely buy until then no cheap China goods more and can also only recommend other buyers, unless the still relatively high price they do not care.
