Provider Notes:Lighting is a critical concern for plant growth in an Advanced Life-support System (ALS). Electric lighting is energy intensive, but it is necessary when balanced against the hazards and limitations of plant growth under natural sunlight on the surface of the moon or Mars. The characteristics of different electric light types are reviewed, and functionality for an ALS is critically examined. Different lighting scenarios previously used in earth-based ALS simulations are highlighted. Light-emitting diodes (LEDs) are a relatively newer plant growth light source, but they are increasingly efficient and possess a variety of other benefits. Intracanopy lighting also has potential to save energy by lighting only areas where photosynthesis is occurring. When the benefits of LEDs are combined with the advantages of intracanopy lighting, electric lighting for ALS becomes increasingly feasible.
