Unfortunately pretty cool ...

Contrary to the promise of a "pleasant warm light color", but the light is very cool, and has an unsightly blue cast, the environment is dull and sallow. If I had to make comparisons, then I would say that it is similar to a relatively weak, cold white neon. For my purpose in living room unfortunately unsuited because the color rather than well-being auslößt discomfort, and therefore I will also return again.

Due to the relatively low angle of radiation and the cold color, it's hard to tell whether the brightness really a 60 watt incandescent lamp, or a 30-40 watt halogen lamp equivalent, subjectively I did it anyway as noticeably darker in comparison to the previously used 60-watt light bulb felt.

Otherwise, in order, the heatsink is quite hot, the glass but only lukewarm, only a very short delay when switching on, no flickering, no humming.
