  •  Lamp Depreciation: Set using the Lamp Depreciation field in the Light Fixture Project Schedule command.

  •  Total Lumens (General): Equal to Lumens/Lamp×NumberofLampsLumens\>/\>Lamp \times Number\>of\>Lamps set in the Light Fixture Project Schedule command.

  •  Total Lumens (Egress): Equal to EgressModeLumens/Lamp×NumberofLampsEgress\>Mode\>Lumens\>/\>Lamp \times Number\>of\>Lamps set in the Light Fixture Project Schedule command.

  •  Total Lumens (IES): The total lumens set in the IES file for the fixture.

    If a number is displayed, the light output from the IES file will be scaled based upon the ratio of the Total Lumens (General) or Total Lumens (Egress) value to the Total Lumens (IES) value.

    If Absolute is displayed, the IES file uses absolute photometry. The total lumens for the IES file are not provided. The light output for the fixture will not be scaled based upon the Total Lumens (General) or Total Lumens (Egress) values.
