Dimmable and bright yes, but often fail to light using a switch that has a soft on feature.

Nice bright bulbs that seem to be holding up well. However, the wifi enabled dimmer light switch that I use to control 4 of these with has a soft on feature, that can't be disabled, that these lights randomly will not illuminate with. Sometime all 4 will light when turned on sometimes only one, or two, or three will illuminate when tuned on. Cycling the switch on and off 2-3 times is sometimes required to get all 4 of my lights to turn on. I believe this problem is caused by my light switch which can only turn the lights on using a soft on feature. As these are dimmable lights you would not think that my switch that when turned on basically starts out dimmed and then ramps up to its setting would cause a problem, but these lights randomly do not illuminate when turned on with this soft on dimmer switch.
