Lamp

Lamp is an item in the special category (subcategory circuit-network) with a stack size of 50; it is a placeable entity that interfaces with the circuit network to serve as a visual indicator and local light source for player-built systems. As a circuit-network device, Lamp can be connected to combinators, wires, or other signal sources to change its on/off state based on signal conditions, allowing it to display status or trigger lighting in automated factories and control setups.
