Bridge the gap between different bulb standards with our E27 to BC Light Bulb Adapter. This essential lighting accessory allows you to use standard Bayonet Cap (BC) bulbs in existing E27 Edison Screw (ES) fixtures, saving you the cost and hassle of replacing entire lamp holders or buying new bulbs. Designed for a secure fit and reliable electrical contact, it is a must-have for any home or workshop.
Seamless Compatibility: Easily converts an E27 male screw base into a B22 female bayonet socket, expanding your options for bulb selection.
Durable Insulated Construction: Manufactured from high-quality, flame-retardant material with robust internal contacts for long-lasting performance.
Tool-Free Installation: Simply screw the adapter into your E27 socket, then push and twist your B22 bulb into place—instant "plug-and-play" functionality.
Compact & Low-Profile: The streamlined design ensures the adapter remains discreet within your lamps, pendants, or ceiling fixtures.
Stable Electrical Connection: Features precision-engineered internal pins to ensure a flicker-free power supply to your bayonet bulbs.
Versatile Use: Ideal for modernizing old fixtures, reusing existing bayonet bulbs in new screw-type lamps, or integrating specialty BC bulbs into ES systems.
This ES-BC Adapter is the perfect solution for:
Home Lighting Upgrades: Using inherited or bulk-purchased bayonet bulbs in newer screw-base floor lamps and pendants.
Temporary Lighting: Quickly adapting work lights or festive bulbs to available sockets on-site.
Smart Home Setup: Fitting BC-style smart bulbs into fixtures that only accept E27 screw bases.
Base Type (Male): E27.
Socket Type (Female): BC (Bayonet Cap).
Material: Heat-Resistant PBT and Brass/Copper Contacts.
Voltage Compatibility: Standard household AC power.
Will this make my light bulb stick out further?
Yes, the adapter adds approximately 2-3cm of length to the bulb base. Ensure your lamp shade or glass enclosure has enough clearance for the slightly increased height.
Can I use this with high-wattage bulbs?
While the adapter is built to handle standard loads, we highly recommend using LED bulbs. LEDs produce significantly less heat, which ensures the longest possible lifespan for the adapter.
Is the bayonet fit secure?
Absolutely. The internal female socket is designed with standard locking slots to ensure your B22 bulb stays firmly in place, even in overhead fixtures.
