Compare Tool Overview
The Compare Tool in Photometric Toolbox allows
you to compare the photometric characteristics of up to three luminaires side
by side. The following capabilities are available:
- The Reports that contain any combination of calculated
metrics and extracted photometric data from PTB's Indoor, Roadway and
Flood reporting tools. The factory provided reports are as follows:
- Dark Sky Report - Includes
metrics associated with exterior light pollution concerns including LCS
- LCS Report - Includes metrics related to the
IESNA Luminaire Classification System (LCS).
- Indoor Report - Includes metrics related to
standardized interior analyses: efficiency, zonal lumens,luminous dimensions,
luminaire spacing, luminance data, CIE type, zonal lumens, LER, and luminaire
- Road Report - Includes metrics related to
standardized exterior analyses: downward efficiency, luminaire watts,
house side and street side zonal lumens, IES classification, longitudinal
classification, cutoff (deprecated), max candela angles and LCS data.
- Flood Report - Includes metrics related to
standardized floodlighting analyses: NEMA type, beam and field angles,
efficiencies (total, beam, field and spill), luminaire watts and max candela
- Visualize the overlapping candela distributions
using 2D horizontal cones and vertical planes or 3D transparent photometric
webs to get a better understanding of how the luminaire distributions
- Normalize the lamp lumens for the selected luminaires
to get an apples to apples comparison or to correct for inaccurate lumen
- Print your reports including specifiable polar
Compare Report - This tab displays
the metrics chosen for inclusion in the Compare Report.
2D Compare Plot - This tab displays
the overlapping 2D vertical planes and/or horizontal cones for the included
3D Compare Plot - This tab displays
the 3D photometric distributions for the included photometric files.
Settings - This dialog allows you
to select your Report Banner as well as specify the Tumble speeds applied
in the 3D Compare Plot tab.
Setup - This dialog allows you to select which metrics to consider
fin the Compare Report tab.
Print - The Print Details dialog
allows you to specify the report's content as well as printer selection
and number of copies.
