1. A circuit for a lighting assembly comprising:
a power supply;
a first light source connected with an output of the power supply;
a second light source connected with the output of the power supply, wherein the first and second light sources are connected with the output of the power supply in parallel;
at least one integrated circuit including a driver, wherein the at least one integrated circuit is configured to regulate current to each of the first light source and the second light source; and
a switch configured to select a brightness level of each of the first and second light sources, wherein the at least one integrated circuit, in regulating the current to each of the first light source and the second light source, is configured to:
reduce a first current to the first light source at a rate of reduction;
increase a second current to the second light source at a rate of increase, wherein the rate of reduction is greater than the rate of increase; and
reduce the first current and increase the second current until a predetermined dimming cycle is complete.
