The dimming function works very well. These are not flimsy lamps. Have converted 8 multi light fixtures to these so far.

The light is immediate and there is no flicker. No flicker and brightened up my mom's house.

Watt incandescent lamp provides 1600 lumens of light. If you can deal with the decreased lumens from what you would expect in a 100 watt bulb, this is a good a great bulb. Brightness is good and have not had to replace a bulb yet.

People have a hard time believing that it is led because the warm color looks so good. Within the limits of an led trying to emulate the look of a filament bulb, these do a very admirable job.

they are not dimmable! As soon as it's less than 100% power they flicker like crazy. They are about as bright as a 40 watt light bulb.

They are pricey, but nowadays especially, quality comes at a premium. Also, they dim nicely without flicker. Durability seem good.
