## Summary description

Synergy21 S21-LED-000349 is a white lamp holder adapter converting GU10 fitting to E14 compatible with LED bulbs. Supplied as one piece, it enables use of E14 LED lamps in fixtures with a GU10 socket, simplifying retrofits and replacements in home or commercial lighting where socket conversion is required.

## Long description

The Synergy21 S21-LED-000349 adapter converts a GU10 socket into an E14 fitting, allowing E14 LED bulbs to be used in luminaires originally designed for GU10 lamps. This single-piece, white adapter is intended for retrofit and replacement situations where changing the existing fixture or wiring is undesirable. It provides a compact mechanical connection that lets small Edison screw (E14) LED lamps work in twist-and-lock GU10 housings commonly found in spotlights, downlights and track lights.
Advantages
The adapter provides a straightforward mechanical conversion from GU10 to E14, enabling quick bulb interchange without modifying the luminaire. It supports LED lamps so energy-efficient lighting options are preserved, and its compact design minimises space used inside recessed or surface fixtures. When installed according to instructions, the adapter maintains stable electrical contact and helps avoid the need for rewiring or socket replacement.
Suitable for
 Retrofitting spotlights, downlights and track lights with GU10 sockets to accept E14 LED bulbs
 Homes and apartments where an E14 lamp option is preferred without rewiring
 Retail and display lighting that requires alternate bulb shapes or lower-wattage LED replacements
 Temporary or trial installations to evaluate E14 LED bulbs in GU10 fixtures
Key specifications
 Adapter type: socket converter from GU10 to E14
 Compatible lamp technology: LED bulbs with E14 base
 Form factor: compact inline adapter suitable for recessed and track fixtures
 Connection: fits GU10 twist-and-lock socket and provides E14 screw fitting
 Material: electrically insulated components with heat-resistant housing for lamp sockets
How to use
Switch off power to the luminaire before starting. Remove the existing GU10 lamp, insert the adapter into the GU10 socket until it seats securely, then screw the E14 LED lamp into the adapter by turning clockwise until firm. After installation, restore power and verify correct operation. If alignment is difficult or the adapter does not seat smoothly, switch off power and re-seat the components to avoid damaging contacts.
Usage recommendations
Use only E14 LED lamps that comply with the adapter’s expected wattage and temperature limits. Confirm that the chosen LED bulb’s physical dimensions and heat dissipation are compatible with the fixture enclosure. Do not use the adapter in damp or wet locations unless the luminaire is rated for such environments and installation follows local electrical codes.
