It would be nice if you could adjust the intensity of the effect, eg. with beacons being affected by only half of the stated energy consumption offsets. This would mean that it'd take 2 rare efficiency 3 modules to reach the optimal energy consumption of -80%, while also reducing the penalties for speed only beacons.

Oh, and when playing with only negative bonuses enabled, a modifier like 0.2 (ie. a legendary efficiency 3 module only reducing power usage by 25%) would also be more balanced.

This used to be the case with the apply distribution efficiency setting since the efficiency of standard beacons was 0.5. I'll consider changing that setting to a universal multiplier since beacon efficiencies may not be consistent now that half their effective efficiency is based on their profile for diminishing returns.

I've replaced the old apply distribution efficiency setting with a multiplier setting in the newest version. If you were using the old setting, you may want to disable the active mod setting (to force all beacons to their original versions) and save your game prior to updating, then enable it again afterward.
