Very good brightness, pure white, slim design, sitting a little wobbly

These LED bulbs replace three about 5 year old 2W LED bulbs in a stairwell. The increase in brightness is enormous, what the progress of LED displays beautiful lighting in recent years. The color is a pure white with no discernible color cast.

Something negative is the fit of the socket. Properly fixed not sit the pears.
Positive is the small size. Some powerful lamps have enormous proportions, which is not likely to ever match.
