LED bulb Synergy21 S21-LED-TOM00070 Warm white 3500 K 5 W GX5.3

Synergy21 S21-LED-TOM00070 is a 5 W LED retrofit bulb with a GX5.3 base that delivers warm white light at 3500 K and a luminous flux of approximately 480 lm. Designed as a low-voltage replacement for small halogen lamps, it provides a wide 120° beam and an estimated lifetime of 40,000 hours, suitable for general illumination and accent lighting in homes and commercial settings.

Advantages

The bulb offers energy-efficient 5 W consumption while producing brightness comparable to low-voltage halogen equivalents, with long rated life that reduces replacement frequency. Its 120° beam provides broad light distribution for fixtures that require wide coverage, and the warm white 3500 K colour gives neutral-warm illumination suitable for living spaces and display lighting.

Suitable for

• Low-voltage fixtures that accept GX5.3 (G4-style) base bulbs
• Accent and display lighting in cabinets, showcases, or retail displays
• General ambient lighting in small luminaires, bedside lamps or task fixtures

When it may not be suitable

This LED bulb is designed for low-voltage fittings with a GX5.3 base and will not fit standard screw or bayonet sockets. It may not be appropriate where very high colour rendering or specialised dimming behaviour is required unless compatibility is confirmed with the fixture or dimmer. For applications needing a narrower beam, higher lumen output, or different colour temperature, choose a different lamp type.

Key specifications

• Rated power: 5 W
• Luminous flux: 480 lm (approx.)
• Colour temperature: 3500 K (warm white)
• Beam angle: 120° (wide beam)
• Estimated lifetime: 40,000 hours
• Base type: GX5.3 (G4-style low-voltage pin base)

How to use

Ensure the fixture accepts GX5.3 low-voltage bulbs before installation. Switch off power to the luminaire, insert the bulb into the socket by aligning the two pins with the fitting, and secure it in place. Restore power and verify operation. For safe operation, use with compatible transformers or drivers rated for LED retrofit bulbs and follow any manufacturer guidance for dimmer compatibility.

What to consider before purchase

• Verify the fixture uses a GX5.3 (G4-style) low-voltage socket
• Confirm transformer/driver compatibility and dimmer support if required
• Check desired colour temperature and beam angle match the application

Usage recommendations

Use this Synergy21 5 W GX5.3 LED bulb as a direct replacement for low-voltage halogen lamps in cabinets, display cases, and small fixtures; verify transformer type and dimmer compatibility for reliable performance and expected lifetime.
