Low Voltage Replacement Bulbs

LED Replacement Bulbs for Low Voltage Landscape Lighting — MR16, G4 & Bi-Pin

Keep every fixture in your low voltage landscape lighting system performing at its best with GLE professional-grade LED replacement bulbs. Available in MR16, G4, and bi-pin configurations, every bulb in our collection is fully compatible with all standard 12V low voltage landscape lighting fixtures — making them the reliable replacement choice whether you're servicing GLE fixtures or maintaining fixtures from any other brand across a larger installation.

Every GLE replacement bulb is LED — no halogen, no incandescent, no compromise on energy efficiency or bulb life. LED technology means dramatically longer service intervals, lower energy draw on your transformer, and consistent light output that doesn't degrade the way halogen bulbs do over time. For installers that means fewer callbacks for bulb replacements. For DIYers that means less climbing around in the dark replacing burned-out fixtures every season.

Choosing the right replacement bulb:

  • MR16 — check your existing fixture for the MR16 designation or the two-pin twist-lock base. The most widely used landscape lighting bulb type across uplights and spotlights
  • G4 — smaller two-pin straight base, common in compact path lights and accent fixtures. Pins are parallel and close together
  • G4 bi-pin — similar to G4 but confirm your fixture's pin spacing before ordering. When in doubt check the existing bulb or fixture spec sheet for the correct base type

Not sure which bulb your fixture takes? Check the existing bulb base type or look up your fixture model — every GLE fixture with replaceable bulbs includes the compatible replacement bulb type in the listing for quick reference.
