The tiny size of these halogen capsule bulbs means that they are often used in decorative light fittings with small shades where standard bulbs wouldn't fit.
(When installing a halogen bulb, make sure that you do not touch the glass part of the bulb with your bare skin - e.g. fingers, as the natural oils from your skin can considerably reduce the life of the bulb)
