In an example, a light-control system includes UV light sources for emitting UV light when activated, a power sensor for measuring an amount of power available, and an activation-control system. The activation-control system can: (a) determine a subset of the UV light sources that are ready to be activated, (b) indicate, in a queue, each UV light source of the subset, (c) arrange, in the queue and based on a hierarchy, the subset in a sequence, and (d) activate, in the sequence, each UV light source of the subset by: (i) determining an amount of power required to activate a next UV light source in the sequence, (ii) determining when the amount of power available is equal to or greater than the amount of power required, (iii) responsively activating the next UV light source in the sequence, and (iv) repeating acts (i)-(iii) until all of the subset has been activated.
