Beacon
Beacon is a building that spreads the effects of inserted Modules to nearby buildings, albeit with reduced efficiency. Multiple beacons can affect a single building, even one that is full of modules.
As of 7.1, only Basic beacon exists.
Basic beacon
Basic beacon has a 9x9 area of effect in which effects of 2 modules are shared at 50% efficiency. 50% efficiency means that 2 identical modules in the beacon have the same effect as 1 module in every affected building.
The beacon is a 3x3 building and consumes 480 W. When the power drops, so does the effect of the beacon. Energy consumption is independent from affected buildings - a beacon that affects no buildings still consumes 480 W, unless it has no modules inserted.
Beacon itself doesn't benefit from the modules inserted, so the energy cost can't be reduced.
With 3x3 size and 9x9 area, the maximum number of affected 3x3 buildings is 12. Alternatively, a single 3x3 building can be affected by 12 beacons.
