I was searching for flicker-free dimmable E12 candelabra bulbs and came across a light bulb database that I haven't seen mentioned here before.
While it isn't as extensive as Lutron's LED compatibility database, the flicker-free ratings on OptimizeYourBiology's light bulb database seem to be very reliable.
I found E12 bulbs and E26 bulbs that are reliably flicker-free with Zooz dimmers, whereas the Feit bulbs they replaced would occasionally flicker.
Here's the database:
They also have a smart bulb database, with flicker ratings.
