Fluorescent light bulbs last much longer than incandescent bulbs, saving money in the long run. While the upfront cost is higher, fluorescent bulbs can last 6,000-15,000 hours compared to 750-1,000 hours for incandescent. They also use one third less energy, reducing electricity bills and greenhouse gas emissions. However, fluorescent bulbs emit an annoying buzz and contain mercury, requiring safe disposal.
