## Long description

Synergy21 74861 is a compact G4 base LED bulb that delivers 140 lm of warm white light at 3300 K using just 2.2 W of power. Designed for small fittings and low-voltage fixtures that accept a G4 capsule, this bulb provides steady, energy-efficient illumination with an expected lifetime of 35,000 hours. Its compact form factor and warm colour make it suitable for accent, cabinet and decorative lighting where a soft, comfortable light is required.
Advantages
This LED bulb offers low power consumption while producing a warm white output comparable to low-wattage halogen capsules. The long rated lifetime reduces the need for frequent replacements, and the stable light output ensures consistent colour rendering over time. Its small size and G4 base make it compatible with many small fixtures, and the 3300 K colour temperature creates a warm atmosphere without excessive yellowing.
Suitable for
 Accent lighting in display cabinets and shelving
 Decorative fixtures and chandeliers that accept G4 capsules
 Under-cabinet and spotlight applications in kitchens and work surfaces
 Small desk or task lamps with G4 sockets

How to use
Ensure the fixture accepts a G4 base and operates at the appropriate voltage for this capsule. With power off, insert the bulb into the G4 socket by aligning the pins and pressing gently until seated. Restore power and verify correct operation. Do not attempt to use this bulb in circuits or fixtures that require integrated drivers or dimmers unless the fixture specification confirms compatibility.
Usage recommendations
Use in enclosed fixtures only if the fixture manufacturer permits LED capsules; avoid exposure to excessive heat or moisture. For optimal lifetime and consistent light output, operate within the fixture's rated voltage range and avoid frequent rapid on/off cycles. Replace bulbs in sets simultaneously for uniform colour and brightness when used in multi-bulb fittings.
