Environmental issues[edit]
Unlike fluorescent and high-intensity discharge lamps, sulfur lamps contain no mercury. Therefore, sulfur lamps do not pose a threat to the environment nor require special disposal[citation needed]. In addition, use of sulfur lamps has the potential to reduce the total amount of energy required for lighting.
Light distribution systems[edit]
Because the amount of light produced from one bulb is so great, it is usually necessary to distribute the light to areas far removed from the lamp. The most common method used is light pipes.
