FAQ

These bulbs fit light fixtures that use an E12 candelabra screw base. That commonly includes chandeliers, wall sconces, decorative ceiling fixtures, some ceiling fans, and certain night-light or accent fixtures that specifically call for an E12 bulb.
B10 refers to the bulb shape, which is a decorative candle-style bulb. E12 refers to the candelabra screw base size. To confirm fit, check your existing bulb markings or the fixture label for an E12 socket.
Yes, these bulbs are labeled dimmable. For best performance, use them with an LED-compatible dimmer. If a dimmer is not designed for LED bulbs, you may notice flickering, limited dimming range, or buzzing.
Make sure your fixture uses an E12 candelabra base and supports LED bulbs. Turn off power before installation, allow the old bulb to cool, and avoid overtightening the new bulb—just screw it in until snug.
Typical signs include the bulb not turning on, intermittent flickering after confirming the fixture and switch are working properly, dim output compared with the other bulbs in the fixture, or color/brightness inconsistency within the same set.
Not necessarily. Flickering can also be caused by an incompatible dimmer, a loose bulb connection, a worn socket, voltage fluctuations, or a fixture issue. First try tightening the bulb gently, testing it in another compatible fixture, or bypassing the dimmer if possible.
