## Long description

Synergy21 S21-LED-TOM00159 is a compact G4-base LED bulb that provides warm white illumination at 3300 K with a power consumption of 1.3 W. Designed as an energy-efficient replacement for low-voltage halogen G4 lamps, it produces 84 lumens and has an estimated lifetime of up to 35,000 hours, making it suitable for small decorative fixtures and retrofit projects requiring a small, warm light source.
Advantages
The bulb combines low power consumption with a long rated lifetime, offering reduced energy use and less frequent replacements compared with traditional halogen G4 lamps. Its small G4 base and compact form factor allow use in tight fixtures and decorative lamps while delivering a consistent warm-white colour temperature of approximately 3300 K.
Suitable for
Low-voltage lighting fixtures that accept G4 bulbs
Decorative lamps and display lighting
Retrofit replacements for halogen G4 lamps
Small task or accent lighting where warm light is preferred
When it may not be suitable
This LED bulb is intended for low-voltage G4 fittings and may not be compatible with mains-voltage fixtures or fittings that require a different base type. It provides modest luminous output (84 lm), so it may not be suitable where high brightness is required for general room illumination.
Key specifications
Power: 1.3 W
Light output: 84 lm
Colour temperature: 3300 K (warm white)
Rated lifetime: 35,000 hours
Base type: G4
How to use
Install the bulb into a compatible low-voltage G4 socket, ensuring power is switched off before replacement. Use in fixtures with appropriate voltage and compatible dimmers only if the bulb is specified as dimmable by the fixture or manufacturer. Handle the bulb carefully to avoid damage to the pins or glass body.
What to consider before purchase
Check that the fixture uses a low-voltage G4 base and the supply voltage matches the bulb requirements
Confirm the light output (84 lm) meets your brightness needs
Verify dimmer compatibility if dimming is required
Ensure physical fit in small or enclosed fixtures
Usage recommendations
Use the Synergy21 G4 LED bulb in low-voltage decorative and task fixtures where a compact, warm-white light source is required; replace halogen G4 bulbs directly in compatible sockets and consider grouping multiple bulbs for higher overall illumination.
