We have a large variety of halogen bulbs, from PAR and MR lamps to small bi-pin, large AR111, and ALR elevator lamps. Halogen bulbs are still prevalent (despite the rise of LED) because of their high luminous output and small size. When replacing a halogen bulb, do not touch the bulb with bare hands. When it heats up, the oils will burn and cause damage to the bulb, decreasing it's life.
