The MR11 GU4 range from Integral LED is manufactured from the latest LED technology and components to ensure superior light output and to offer excellent energy savings of up to 85% when compared to halogen equivalent products. Integral LED MR11 lamps are designed to retrofit easily into existing MR11 halogen lamp downlight fittings.

MR11 lamps with a GU4 base are not to be confused with its larger cousin the MR16 lamp (with a GU5.3 base). The MR11 lamp is considerably smaller with a width of 35mm.
