Dupes will attempt to sleep in unlit areas if they pass out on the floor. Light interferes with Duplicant's sleep, so lights near Cots will negatively affect their stamina recovery.Mess Table, Lavatory, and Sink count as workspaces and benefit from the Lit Workspace speed bonus.Printing Pod has a large light source, making it a good area for recreational building in the early game.Algae Terrariums gain a minor efficiency bonus in direct light.In the remaining 87.5%, it follows a sine wave with a half-period of 0.875 cycles and a maximum of 80000 Lux. During 12.5% of the cycle (during night) the intensity is 0. The intensity of sunlight gradually changes by time of day. This is in most part due to the fact that the game maps the light exposure percentage (1 - the sum of the effective absorption of all cells above) to an integer between 0 and 255, truncating the decimals, and in lesser part because of floating point conversion errors result in slightly off values in the elements' potential light absorption factors (). The actual proportion of unabsorbed light is on average around 0.2% lower than what the above calulations would suggest. Hence, shaded light doesn't just approach 0 intensity, but can quickly turn pitch black. The resulting percent of absorbed light is relative to the base intensity of the sunlight (), not the intensity of the light present in the cell (). An element's effective absorption () is its potential absorption factor () multiplied by its mass () / 1000 g for gasses, kg for liquids (maximum 1). Unlike other light sources, which either have a circular or a cone shape, and lose their intensity with distance from the lightsource, the sun's light travels downwards indefinitely, if not absorbed by some element. Sunlight shines down from the top of the world. Natural sunlight can be found in the Space Biome.The Printing Pod provides a large amount of light.Floor Lamps, Ceiling Lamps, and Sun Lamps can be used to create light using electricity.Light Levels Brightness Ībove 40000 Lux: Bright and Cheerful status for DuplicantsĪbove 72000 Lux: Intensely Bright status for Duplicants and Sunburn 'Dim' light is sufficient to provide the 'Lit Workspace' work speed bonus. Use the Light Overlay to see which tiles are lit at any time. Light can also be converted into power using Solar Panels, and some plants (Bristle Blossom and Gas Grass) need illumination to grow (while the Dusk Cap needs darkness and doesn't grow when exposed to light). Light increases Duplicant work-speed by 15% and improves decor, which reduces stress. You can help Oxygen Not Included Wiki by expanding it.
