## Long description

Synergy21 85498 is a compact LED bulb with a GX5.3/G4 bi-pin base, rated at 12 W and finished in white. With a diameter of 1.7 cm and a height of 10 mm, this single-pack lamp is designed for fixtures that require small low-voltage bi-pin lamps. The lamp is suitable for retrofits where halogen GX5.3 or G4 bulbs are being replaced by LED equivalents and can be used in residential and commercial task, accent or low-profile lighting applications when matched with an appropriate LED-compatible holder or driver.
Advantages
The small physical size and bi-pin GX5.3/G4 interface make this LED bulb straightforward to install in compact fixtures that accept two-pin lamps. Its 12 W rating provides LED-level energy efficiency compared with equivalent halogen lamps, and the white finish integrates visually into most fixtures. The single-pack format supports targeted replacements and maintenance needs while the standard pin spacing and secure contact design help ensure reliable electrical connection in suitable sockets.
Suitable for
 Replacing halogen GX5.3 or G4 lamps with LED equivalents
 Downlights, spotlights and display lighting that accept bi-pin low-voltage bulbs
 Task and accent lighting in residential and commercial interiors
 Low-profile fixtures with limited internal space
Key specifications
 Socket type: bi-pin compatible with GX5.3 and G4 bases
 Power: 12 W
 Colour/finish: white
 Diameter: 1.7 cm
 Height: 10 mm
 Pack quantity: single bulb
 Intended voltage class: low-voltage bi-pin applications (confirm driver/transformer compatibility)
How to use
Before installation, switch off power to the fixture and allow any lamps or drivers to cool. Remove the existing lamp and check the socket or adapter for compatibility with GX5.3/G4 pins. Insert the Synergy21 85498 lamp by aligning the two pins with the socket and pushing gently until the pins are fully seated. Restore power and verify the lamp operates correctly. If the fixture uses a separate transformer or LED driver, ensure that its output matches the lamp's requirements.
Usage recommendations
Use the bulb only in fixtures and holders rated for low-voltage bi-pin lamps and confirm compatibility with existing drivers or transformers. Avoid excessive force when inserting pins to prevent damage. Follow local electrical safety requirements and consult a qualified electrician if unsure about wiring or compatibility.
