Halogen Light Bulbs. Halogen light bulbs provide a cool white light and are usually used in under-cabinet lighting, pendant lighting or recessed lighting. They can be dimmed, but run quite hot, and shouldn’t be touched with bare hands, as the oil from your skin can cause the bulb to heat up too quickly and burn out.
