The brightest smart bulbs I know are the LIFX.
The white only bulbs are rated at 890 lm, a 75 W equivalent, and happen to be on sale right now at Best Buy.
The color bulbs go to 1000 lm, but are more expensive. Those are the brightest I know.
Note, though, that these also run physically hot and are not a conventional A19 shape so they don’t fit all fixtures.
