Abstract: In accordance with the present disclosure, a control circuit may be employed for controlling delivery of energy from an input of a lamp assembly to a load of the lamp assembly. The control circuit may transfer a first amount of energy from an input to a load (e.g., comprising one or more light-emitting diodes) to cause the load to generate light external to the lamp assembly in accordance with a control setting of a dimmer indicating a user-desired amount of energy to be transferred to the load. The control circuit may also transfer a second amount of energy from the input to a second load to cause the second load (e.g., comprising one or more lower-efficacy light-emitting diodes) to dissipate the second amount of energy external to the lamp assembly, wherein the second amount of energy comprises energy present in the input signal other than the first amount of energy.
