Integral 3.7W Warm White LED MR11


The Integral 3.7W LED MR11 is a non-dimmable replacement for a 20W halogen equivalent, offering over 80% savings in energy. Its lifespan of 15,000 hours is up to five times greater than that of a 12V halogen bulb, so maintenance costs are reduced as well. This great-value bulb is compatible with most existing transformers.

Designed with a thermally efficient body using a plastic and die cast aluminium construction, the Integral 3.7W LED MR11 delivers a reliable performance. An anti-glare refractor ensures a comfortable, smoothly dispersed light.

An A+ energy-rated bulb, the Integral 3.7W LED MR11 uses four top-quality Nichia LEDs to emit 280 lumens of warm white 2700K (CCT) light. This equates to an excellent luminous efficacy of 76 lumens per watt, with a peak luminous intensity of 800 cd.

Warm white light is an excellent choice for most areas of the home (except perhaps a kitchen) and perfect for hospitality venues as well as some retail applications.

only bought the one to see if it would replace the Halogen ones in our motorhome, to save on the leisure battery. Fits and works perfectly, and will be buying more in a week or two!!
