LED Spotlights are designed to replace your existing halogen range. LED lighting is highly efficient as it uses 90% less energy than the traditional lighting sources - saving you more money. We aim to make choosing which product is right for you as easy as possible; whether you\'re looking for a particular size, colour, wattage or lumen output. This particular spotlight is non-dimmable, however, we do have dimmable GU10 spotlights available in our spotlight categories. If you are choosing a dimmable LED, you may require a Trailing Edge dimmer switch. Please contact us if you’re unsure on your dimmer switch compatibility.
