Light

Most of the asteroid is dark. Light sources such as the Ceiling Light or Shine Bug improves Decor and gives Duplicants a boost to their productivity. Many plants are also sensitive to the amount of light they receive.

Light Sources

The Lamp and Ceiling Light produce a decent amount of light when powered. The Shine Bug naturally emits a halo of light. Strong solar light is available on the surface during daytime.

Measuring Light

The amount of light on a cell is measured in Lux. Lux has a dramatic range - A simple Ceiling Light produces 1800 Lux, while the sun can produce values as high as 80000 Lux. The Solar Panel generates power proportional to how many Lux it is exposed to.
