Frequently Asked Questions

Q: What does "G4 bi-pin base" mean and will these G4 LED bulbs fit my existing fixtures?

A: The G4 bi-pin base refers to the two small metal pins spaced 4mm apart at the base of the bulb. These G4 LED bulbs are a direct drop-in replacement for any standard G4 halogen or G4 LED fitting. Simply pull out your old bulb and push in the new one — no tools or adaptors required. Always check that your fixture operates at 12V before installing.

Q: Are these G4 LED bulbs dimmable?

A: No, these bulbs are non-dimmable. They are designed to operate at full brightness at all times, providing consistent, flicker-free light. Using them with a dimmer switch is not recommended and may cause flickering or reduce bulb lifespan.

Q: Which color temperature should I choose — 2700K warm white or 6000K cool white?

A: Warm white (2700K) produces a soft, golden glow similar to traditional incandescent or halogen bulbs — ideal for living rooms, bedrooms, and anywhere you want a relaxed, cozy atmosphere. Cool white (6000K) produces a bright, daylight-style light that enhances focus and clarity, making it great for kitchens, workspaces, display cases, and task lighting areas.

Q: How much energy do these LED bulbs save compared to halogen?

A: Each 3W G4 LED bulb replaces a 30W halogen bulb, delivering approximately 90% energy savings per bulb. Over the lifespan of a single bulb and across a 10-pack, the cumulative savings on your electricity bill can be significant — especially in fixtures that are left on for extended periods.
