Modifying Luminaire Definitions - Concepts

The Modify-Luminaire-Define command invokes the Define Luminaire dialog. Previously defined luminaire types can be easily redefined to reflect changes from simple (e.g., change Luminaire Watts) to complex (e.g., change associated photometric file). All luminaire locations previously placed in the graphics area will immediately be updated to reflect the changes made in the Define Luminaire dialog, provided that the luminaire Labels are the same. If the Label has changed, you have  in effect created a new luminaire definition. In this case, the original luminaire definition remains unchanged.

Be aware that many of the input cells have direct bearing on the AGi32 computations and will require recalculation when changed.

  1. The Total LLF is a direct multiplier to the computed values.
  2. The Lumens per Lamp value represents the lumens for one lamp, and is generally extracted and used directly from the selected photometric file. Changes to this value will result in proportional changes to your calculated values. However, if this value is -1, this indicates that the luminaire was tested with absolute photometry. In this case, the Lumens per Lamp cannot be changed.
  3. The Luminaire Watts cell is only used in LPD Area calculations (Lighting Power Density) and should represent the entire wattage requirements of the luminaire (lamps and ballast) not just lamp wattage.
