The Summary tab provides the cover page for the IES Flood Report. Three sections are shown in this tab: the IES file description, calculated characteristics for the photometric file and axial candela.
Banner
You may append a custom banner to your report by clicking in this graphic box. Once in the Banner dialog, you may paste a banner image from the Windows clipboard (use Ctrl-V) or import a graphics image from anywhere on your computer or network. The graphic image must be in BMP, WMF or JPG format.
Luminaire Image
You may associate a luminaire image with this report by clicking in this graphic box. Once in the Luminaire Image dialog, you may paste a banner image from the Windows clipboard (use Ctrl-V) or import a graphics image from anywhere on your computer or network. The graphic image must be in BMP, WMF or JPG format.
Note: If the photometric file was obtained from the InstaBase, the luminaire image from the InstaBase is used.
Descriptive Information
This section extracts all descriptive information above the TILT=NONE line in the photometric file. The type of information displayed and completeness of the description is at the manufacturers discretion.
Photometric files using the IESNA 95 or 2002 format will have keywords at the beginning of each line. Keywords are bracketed words used in photometric files to label data. Any number of defined keywords may be used to describe a file.
The descriptive information displayed in this section is not editable here. You must open the photometric file with the Edit Tool to make any changes to its contents.
Characteristics
The characteristics displayed in the Summary tab are calculated directly by Photometric Toolbox or extracted directly from the photometric file.
NEMA Type - The NEMA typing is determined by the location of the 10% maximum candela value in the axial angles of the Type B web. For example: If 10% of the maximum candela value falls between 46 and 70 degrees the designation is NEMA Type 4 in that direction (horizontal or vertical).

* NEMA Type 0 is actually considered a spotlight instead of a floodlight.
Maximum Candela - This value is the maximum candela value found in the IES photometric file. This value is important as it relates to the computation of the NEMA beam spread (calculated using 10% of the maximum value).
Maximum Candela Angle - The angular location of the maximum candela (degrees horizontal by degrees vertical).
Horizontal Beam Angle - The "Beam" of the floodlight is defined by the location of 50% of the maximum candela in the horizontal and vertical (Axial) directions. Horizontal Beam angle is provided in total degrees left and right of beam center.
Vertical Beam Angle - Vertical Beam angle is provided in total degrees above and below beam center.
Horizontal Field Angle - The "Field" of the floodlight is defined by the location of 10% of the maximum candela in the horizontal and vertical (Axial) directions. This is the same as the IESNA Type designator. Horizontal Field angle is provided in total degrees left and right of beam center.
Vertical Field Angle - Vertical Field angle is provided in total degrees above and below beam center.
Lumens Per Lamp - The manufacturers rated lumen output per lamp. This value is not applicable for or absolute photometry.
Total Lamp Lumens - Lumens Per Lamp * Number Of Lamps. This value is not applicable for absolute photometry.
Luminaire Lumens - Total Lumens exiting the luminaire (this is a calculated metric).
Beam Lumens - Accumulated total lumens within the "beam" designated by the 50% maximum candela.
Beam Efficiency - The percentage difference between the beam lumens and the rated lamp lumens.
Field Lumens - Accumulated total lumens within the "field" designated by the 10% maximum candela.
Field Efficiency - The percentage difference between the field lumens and the rated lamp lumens.
Spill Lumens - Accumulated lumens outside the "field" boundary.
Total Lumens - The summarization of Field Lumens and Spill Lumens found in the candela exploration.
Total Efficiency - The ratio of the accumulated Total Lumens (Field + Spill) to the rated lamp lumens.
Total Luminaire Watts - The luminaire wattage extracted from the photometric file. It may be modified by using the Edit tool.
Ballast Factor - The ballast factor extracted from the photometric file. It may be modified by using the Edit tool.
Axial Candela
This section displays the Axial Candela which is the candela for vertical angles along 0-degrees horizontal and for horizontal angles across 0-degrees vertical. This data is used to generate the Axial Display graphs.
