How to choose a GU10 bulb

GU10 or MR16? GU10 bulbs have two thick pins with feet that twist and lock, and run straight off mains power. MR16 (GU5.3) bulbs have two thin pins that push in and usually need a 12V transformer. The two are not interchangeable, so check your old bulb first.

Warm or cool white. Warm white suits living areas and bedrooms. Cool white suits kitchens, laundries and workspaces.

LED or halogen. A 6W to 7.5W LED GU10 replaces a 35W to 50W halogen, runs much cooler and lasts far longer. Halogen is still handy where an existing dimmer is not LED-compatible.
