Review on 6-Pack 60W Equivalent LED Edison Bulbs - 4000K Neutral White, Dimmable ST19 Vintage Filament by Mark Holloway

Very fast shipping. The bulbs are packaged in a clear plastic clamshell for protection. We had swapped out most of our incandescent lights years ago, but couldn't use the non-dimmable LEDs in several locations. One was a 4-light fixture over our bathroom vanity. These have the same pleasing color as the incandescents they replaced, but I had to leave one incandescent bulb in the fixture until I swapped out the high-end Leviton MicroDim switch with a Lutron Maestro dimmer compatible with LED lights. These LED bulbs work perfectly over the full range with the new dimmer switch. Then as a test I tried one of these bulbs to replace a LED bulb in a hallway fixture controlled by a Leviton DHC dimmer switch. The new bulb worked fine over most of its range, but at max switch setting its brightness dropped about half. This again must be some sort of interaction with the old dimmer switch.Interestingly, these bulbs work fine over their full range in another location fed by a low-end dimmer that has a slider to set the brightness. The nice thing about these bulbs is that unlike incandescent bulbs the color temperature remains constant over the full brightness range. Since these are only a week old, I can't comment on their longevity.
