Collection: Halogen GU10

GU10 halogen floods at 20W, 35W and 50W on 120V, delivering 400 to 700 lumens at a 30° beam, including glass-covered and cool-beam versions, in singles and two-packs.

GU10 is a line-voltage twist-lock base, which is what separates it from the 12V bi-pin lamps it resembles — no transformer, and it will not fit a GU5.3 fixture. Voltage, base and beam angle are stated on every SKU because that combination is where substitutions go wrong.

Track heads and recessed accent fixtures still run large installed bases of GU10 halogen. Buyers converting will find the direct replacement in LED spotlights; the 12V equivalent is MR16 GU5.3.
