Halogen bulbs contain a small capsule filled with Halogen gas, which emits a bright white light. Long life and full spectrum Halogen bulbs use less energy and last longer than standard incandescent bulbs of the same wattage. The life of these bulbs is around 2,000 to 10,000 hours or two to five years.
Linear fluorescent bulbs, also known as fluorescent tubes, are more energy efficient than incandescents or halogens because they don't produce much heat. These are the thin, long tube lights often found in kitchens for under-cabinet lighting, or in garages, workshops, and basements. The tubes can last from 10,000 to 44,000 hours—10 to 40 times longer than incandescent lights. Fluorescent bulbs require and are powered.
