## Summary description

Synergy21 S21-LED-000252 is a black lamp holder designed for E27 fittings and compatible with LED bulbs. Supplied as a single unit, it also includes an E14 adapter to fit smaller caps. Suitable for replacing or installing household light fixtures where LED compatibility and a compact, adaptable socket are required.

## Long description

Synergy21 S21-LED-000252 is a black lamp holder adapter that converts an E27 screw socket to accept E14 LED bulbs. Supplied as a single unit, the adapter preserves the electrical contact required for standard household voltages and provides a compact solution for using smaller-base LED lamps in fittings originally designed for E27 bulbs. The converter is suitable for table lamps, ceiling fixtures, chandeliers and other household luminaires where replacing the socket is impractical or unnecessary.
Advantages
The adapter offers a straightforward mechanical and electrical solution for fitting E14 LED lamps into E27 fixtures without modifying the existing lamp holder. Its compact design minimizes visual intrusion into the luminaire while maintaining reliable contact with the bulb. The construction supports repeated bulb changes and compatibility with a wide range of E14 LED lamp shapes and power ratings intended for household use.
Suitable for
 Converting existing E27 fixtures to accept E14 LED bulbs
 Fitting smaller-base LED lamps in chandeliers and decorative luminaires
 Retrofitting table lamps and floor lamps without replacing sockets
 Temporary or permanent installations where only the bulb base differs
Key specifications
 Input socket type: E27 (screw-in)
 Output socket type: E14 (screw-in)
 Intended lamp type: LED bulbs with E14 base
 Compatible voltage: standard household mains voltage (AC)
 Form factor: compact inline adapter for minimal clearance
 Material: electrically insulated housing with conductive contacts
How to use
Switch off power to the lamp or fitting and allow any installed bulb to cool. Screw the adapter into the existing E27 socket until it is firmly seated, then screw the E14 LED bulb into the adapter. Restore power and verify correct operation. To remove, switch off power and unscrew the bulb and adapter in reverse order. Do not force components and ensure the bulb and adapter are fully seated to maintain safe electrical contact.
Usage recommendations
Use the adapter only with LED bulbs specified for E14 bases and within the voltage rating of the fixture. Avoid use in fully enclosed luminaires unless the LED bulb is rated for enclosed fixtures. Monitor temperature during initial operation; if the adapter or bulb becomes unusually hot, discontinue use and check compatibility. Regularly inspect the adapter and contacts for wear, damage or corrosion and replace if any faults are found.
