FAQ

This bulb is designed for fixtures that use a G4 bi-pin base and run on 12V AC or 12V DC power. It is commonly used in landscape lights, under-cabinet lighting, puck lights, RV fixtures, marine lighting, and decorative accent fixtures that originally used a G4 T3-style halogen bulb.
This 2W LED bulb is intended to replace a 30W G4/T3 halogen bulb while producing about 250 lumens of warm white 3000K light. It is a lower-wattage alternative for the same G4 bi-pin socket when the fixture uses 12V power.
No. This is a 12V AC/DC G4 bulb and should only be used in fixtures designed for 12-volt input. It is not made for direct use on standard 120V household power unless the fixture has the correct transformer or driver.
It is described as dimmable, but dimming performance depends on the transformer and dimmer already installed in the fixture. For best results, use it with a compatible low-voltage dimming system. If your current setup was designed for halogen bulbs, occasional flicker, limited dimming range, or dropout can happen if the transformer or dimmer is not LED-compatible.
A 3000K bulb produces a warm white light. It is softer and warmer than cool white bulbs, making it a common choice for accent lighting, cabinet lighting, decorative fixtures, and spaces where you want a halogen-like color tone.
Confirm three things: the fixture uses a G4 bi-pin socket, the system voltage is 12V AC or DC, and the bulb shape has enough room inside the fixture. If you are replacing a halogen bulb in an older low-voltage fixture, it is also smart to check whether the transformer and dimmer are compatible with LED bulbs.
The most common causes are an incompatible transformer, an older halogen-only dimmer, unstable low-voltage output, or poor contact at the bi-pin socket. In some landscape, RV, or cabinet-lighting systems, the original transformer expects a higher halogen load and may not regulate properly with low-wattage LED bulbs.
