The Überschrfift says it almost everything. The light color is absolutely fine, the promised brightness comes out well. Only sometimes flickers slightly and she is hotter than some other model. Okay, 6 watts you have taken away with this small heatsink times ... The development in this area is indeed currently so fast that I can not say whether I would buy the lamp again. For the current price probably already because I'm to blame, that I my copy (I have just one) due to the sporadic slight flicker not send back. The other 3 lamps (from other manufacturers - I test different) in my lamp cover up the beautiful. ;-)
