## Long description

Synergy21 78481 is a G4-base LED bulb delivering 3 W of power and 210 lm of luminous flux in a warm white shade of 3300 K. Engineered for compact luminaires and accent lighting, this lamp provides efficient illumination with an estimated lifetime of 35,000 hours. Its small G4 base and low heat generation make it suitable for enclosed or limited-space fittings where a warm colour tone and long service life are required.
Advantages
The bulb offers low energy consumption and a high lumen-to-watt ratio, providing clear warm-white light while reducing operating costs compared with equivalent halogen G4 lamps. With a rated lifetime of 35,000 hours and stable light output, it reduces maintenance frequency in display cases, under-cabinet installations, and other small fixtures. Its compact form factor and minimal heat emission improve compatibility with sensitive materials and confined housings.
Suitable for
 Display cases and showcases
 Under-cabinet and task lighting in kitchens
 Small decorative and accent luminaires with G4 sockets

Key specifications
 Base type: G4
 Power: 3 W
 Luminous flux: 210 lm
 Colour temperature: 3300 K (warm white)
 Rated lifetime: 35,000 hours
 Suitable for enclosed or compact fixtures with a G4 fitting
How to use
Ensure the fixture is powered off before installing the bulb. Insert the G4 pins into the corresponding socket, making sure the bulb is seated securely. This bulb is intended for low-voltage G4 circuits; confirm compatibility with the luminaire's supply and, if required, the existing transformer. After installation, switch the power on and verify stable light output. For replacement, remove the old bulb once cooled, and fit the new Synergy21 78481 following the same steps.
Usage recommendations
Use in fittings rated for G4 bulbs and compatible low-voltage drivers; avoid direct exposure to water unless the luminaire is rated for damp or wet locations. For best colour consistency, use bulbs from the same production batch in multi-lamp installations. Allow short warm-up time for the LED to reach full luminous output.
