The LEDs are good. I think they can be called "white" (but warmer would be better, these are not for any place). The direction can be adjusted almost 360°, although the fact is not obvious, some people think there is no adjustment.
The driver is overloaded. The transformer is more than 60°C hot with the lamp opened, LEDs moved away (the LED board is less hot, about 50°C).
I measured 7.9W AC, power factor 55%, 5.3W DC (18.9V 0.28A DC or 3.15V 20mA per LED). The driver seems to be only 67% effective, which defeats the "green" idea.
Not quite a replacement of 60W incandescent. Perhaps 50W.
