Halogen Bulbs Halogen bulbs have some differences from standard incandescent lightbulbs. They are generally smaller, the filament runs at a higher temperature, and they have a quartz (rather than glass) envelope. They may also operate at lower voltage. Consider a 12 V, 50 W halogen bulb for use in a desk lamp. The lamp plugs into a 120 V, 60 Hz outlet, and it has a transformer in its base. Suppose the transformer in the base of the lamp has 500 turns of wire on its primary coil. How many turns are on the secondary coil? A. 50 B. 160 C. 500 D. 5000
