Lighting sensible loads are selected and automatically added to the calculation through the Lighting form accessed by clicking on the Lighting Button. LED or Tungsten (incandesent) and fluorescent lighting types may be selected either simultaneously or exclusively. Default typical Wattage values are automatically entered for either LED or flourescent lighting type but these may be over written simply by typing new values in the appropriate input boxes. Typically, Wattage values for LED (Light Emitting Diode) would be entered at around 20% of values entered for Tungsten. Multiples of different lighting types may be simultaneously selected by repeating clicking on the Add button. Similarly, by highlighting previously entered selections, clicking on the Delete button will remove from the calculation only the data corresponding to the highlighted selection.
