I've searched the world over and all I can find the A21 size.
From a quick google search :

Lowes sells this brand - but I didn't see this exact bulb on their
website.

I just bought some of those today at Menards, warm white instead of daylight,
and even though they say it replaces a A19 bulb it's really a A21 size.
I can use them but I'd have to buy new globes so the bulb doesn't hang out the
bottom. Bummer
Menards dot com only sells one Feit dimmable LED
if you trust their web site
.... it's a flood light not the one in the web link.
.... they do sell a lot of Sylvania, though ..
You probably bought the cheaper non-dimmable unit ..
