Fluorescent lamps cast light by exciting mercury vapor with an electric current. While these are typically more expensive than incandescent styles, the fluorescent lamps efficiently convert electrical energy into useful light and lower energy costs in the long-run. The lights are designed for a strong working longevity and to meet even the most specific requirements. Varying in intensity, bulbs can be either mounted or strung from above.
