1. A lighting system, comprising:
a housing having cavity, an area, and a support surface; the area being at least one item selected from the group consisting of a translucent area, a transparent area, and an open area;
a candle atop the support surface;
a plurality of discrete light emission points (DLEPs) positioned in the cavity for emitting light through the area, at least one of the DLEPs extending from a lower face of a substrate when the lighting system is in an operating configuration;
a power source; and
a controller in communication with the plurality of DLEPs and the power source to cause the plurality of DLEPs to simulate a burning wax candle;
wherein the controller:
at time T1:
actuates a first of the DLEPs according to a first intensity value; and
actuates a second of the DLEPs according to a second intensity value; and
at time T2:
actuates the first DLEP according to an altered first intensity value, the altered first intensity value being determined by combining the first intensity value with a first change value, the first change value being within a first predetermined range; and
actuates the second DLEP according to an altered second intensity value, the altered second intensity value being determined by combining the second intensity value with a second change value, the second change value being within a second predetermined range;
wherein an increase from the first intensity value to the altered first intensity value simulates an increase in optimal flame chemistry;
wherein an increase from the second intensity value to the altered second intensity value simulates an increase in optimal flame chemistry;
wherein a decrease from the first intensity value to the altered first intensity value simulates a decrease in optimal flame chemistry;
wherein a decrease from the second intensity value to the altered second intensity value simulates a decrease in optimal flame chemistry;
wherein an increase in absolute value of the first change value simulates an increase in turbulence;
wherein an increase in absolute value of the second change value simulates an increase in turbulence;
wherein a decrease in absolute value of the first change value simulates a decrease in turbulence; and
wherein a decrease in absolute value of the second change value simulates a decrease in turbulence.
