Sylvania GU5.3 LED bulbs are also known as MR16 bulbs. These light sources, also called spots, are used both as accent- or as generic lighting. The beam angle of 36 degrees is suitable for both and makes this spot very easy to apply. Replace your current, conventional lighting by LED lighting and start saving energy! Because of the same fitting, replacement is very easy. But you will need to check your light color and wattage, to retain the same light effect as your current bulb when buying your Sylvania GU5.3 LED bulb.
