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 bulbs are designed to retrofit easily into existing MR11 halogen bulb downlight fittings.

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