These are just the right brightness for your kitchen. They fit perfectly in my ikea led lamp. They are shorter than a regular bulb so they fit in my fixture easier.
They are of lower intensity and the more of them you have, the brighter they get. I believe they were largely meant to be decorative and ultimately to supplement lighting that came from separate decorative wall sconces.
The lights work but they do not stand up straight in the base some wobble and fall sideways. I have problems with the lights intermittently blinking, even when not dimmed. No flicker w/ filament bulbs.
