Incandescent bulbs are notorious for being inefficient, as they produce more heat than light and burn out quickly, explains the California Energy Commission. It's unusual for a regularly used incandescent bulb to last more than 1,000 hours. They also begin to dim over time. These bulbs are still, however, a common type of light bulb used by consumers. The bulbs come in a variety of sizes and shapes, though the bulb most often used is the A-shape with a medium base.

Halogen lights give off a brilliant white light and are far more energy-efficient than regular incandescent light bulb options. They last up to three and a half times longer than regular bulbs. Halogens come in a variety of shapes and sizes including the same size and shape as the A-shape incandescent bulb.These bulbs also do not flicker or dim with age. A disadvantage to halogen light bulbs is that they are very hot and should be kept away from children.
