G4 LED Bi-Pin Light Bulbs, 3W 20W-Equivalent AC/DC 12V T3 Bulbs in Warm or Cool White, 10 Pack
G4 LED bi-pin bulbs replace compatible low-voltage halogen lamps in landscape fixtures, RVs, courtyards, puck lights, cabinets, post lights and recessed accents. Each compact 3-watt T3 bulb produces 240 lumens while using far less power than the listed 20-watt halogen equivalent, bringing useful light to small fixtures.
Choose warm white 3000K or a cooler white option in the ten-pack, then confirm the fixture has a G4 bi-pin socket and stable AC or DC 12V power. These bulbs are non-dimmable and slightly larger than many halogens at 0.47 x 1.42 inches. If an older transformer causes flicker, use a compatible LED driver or retain one halogen lamp in the circuit as the source guidance describes.

Frequently Asked Questions
Can these G4 bulbs run on either AC or DC power?
Yes. They are listed for stable AC or DC 12V systems. Do not connect them directly to household line voltage.
Can I use the bulbs with a dimmer?
No. The G4 LEDs are non-dimmable and may flicker or make noise on a dimmer or unstable 12V supply.
Will the LED fit where my halogen bulb was installed?
Measure first. Each LED is approximately 0.47 x 1.42 inches and may be larger than the original halogen lamp even though both use G4 pins.
What can reduce flicker on an older transformer?
The source recommends changing to a compatible LED driver or leaving one halogen lamp in the system when a full LED conversion causes flicker.
