Is this G4 LED bulb compatible with my existing fixture?
This G4 LED bulb works with AC/DC 12V low-voltage systems only. It is not compatible with 120V fixtures, dimmer switches, or unstable transformers. For best performance, we recommend using a dedicated LED driver.
Why does the bulb flicker or make noise after installation?
Flickering or buzzing is usually caused by an incompatible transformer.
To solve this:
1. Replace your old halogen transformer with an LED driver.
2. Keep one halogen bulb in the same lighting circuit to stabilize the load.
Is this bulb the same size as a traditional G4 halogen bulb?
No. This LED bulb is larger than traditional halogen G4 bulbs.
Bulb size: 1.46 × 0.51 inches.
Please check your fixture clearance carefully before purchasing to ensure proper fit.
Can this bulb be used with a dimmer switch?
No. This G4 LED bulb is non-dimmable.
Using it with a dimmer or unstable voltage may cause flickering, noise, or malfunction.
Why doesn’t the bulb turn on?
Common reasons include:
Incorrect voltage (must be 12V AC/DC)
Incompatible or aging transformer
Loose pin connection
Please verify voltage and ensure the bi-pin base is fully inserted.
