Waste of money for me. Purchased 5 220v E17 Warm White bulbs. None of them turn on. Tried in both dimmed sockets and non-dimmed sockets. None of them turn on. I have sockets with 17 LED bulbs purchased from Aliexpress, and those bulbs work. I replace those bulbs with these, and no light shines. Beware.
Pretty good. When my touch dimmable lamp is on lowest setting ,the bulb flickers . When lamp off, bulb faintly glows. Apart from that, bulbs are great.
