INSTRUCTIONS: The estimator assumes that the system can be operated at three settings: Full Power, Dimmming Setting 1 (for example, 70% power) and Dimming Setting 2 (say, 50% power). Enter the fraction of time the system is being operated at each setting, e.g. 20% of the time at full power, 50% of the time at 70% power, and 30% of the time at the 50% power setting. Then press "Calculate".
