Widely used in ceiling downlighters and recessed spotlights, choose from our Osram Decostar 51 dichroic range or our Osram energy saving IRC MR16 bulbs. The Osram IRC energy saving light bulbs give an impressive energy saving of up to 40% and last 5 times longer than standard MR16 bulbs. If you have a 50 watt halogen bulb installed the equivalent Osram IRC only uses 35 watts of power but has the same brightness.
