1. A light, comprising:

  • (a) a light source including at least one LED;

    (b) a power source configured to provide power to said at least one LED;

    (c) a sensing element configured to sense at least one of voltage and current at said at least one LED, and configured to output a feedback signal to said power source based on the sensed at least one of voltage and current; and

    (d) a control circuit connected to said sensing element and configured to control the feedback signal output by said sensing element, wherein said control circuit stores data points of a dimming operation of an incandescent light source and controls the feedback signal output by said sensing element to simulate the dimming operation of the incandescent light source based on the stored data points.
