The MR11 halogen is commonly used in spot lights, reading lights and extractor hoods and is easily replaced with an LED alternative. The MR11 halogen is easily identified as a conical shaped lamp with a 35mm diameter and two short pins spaced 4mm apart. If the diameter of your lamp is larger, please take a look at our MR16 section. The 6-LED MR11 is the 10W halogen replacement and provide a convenient replacement as the cap used is exactly the same size as the halogen. All control circuitry for the LEDs is located within the cap so it is just a case of remove the halogen and replace with our LED alternative.
