New features / enhancements:

1.    New file format

The existing project file formats for Lighting Reality PRO Roadway and Outdoor has been in use for over 20 years, during which time there have been many changes and additions to the format. The move to LR Studio will require additional changes which the current format can not support reliably, so a new format will be used. Both Outdoor and Roadway from version 2.3 will support the new file format for export of projects. Import is supported, but there will be restrictions due to the addition of new functions in LR Studio which are not supported in Lighting Reality PRO. Files have the extension .LRSA for Outdoor exports and .LRSR for Roadway exports.

A new menu item under “File” allows access to this format.

2.    Licence mobility – ability to release licence & reactivate on new PC

Prior to v2.3 Lighting Reality PRO could only be activated on a single Windows PC at any one time. The transfer of a licence to a new or replacement PC is supported, but requires a request to Lighting Reality support to reset the licence so it can be activated on a new PC.

V2.3 now allows a user to release the licence on an existing PC and then activate the same licence on another PC. The purpose of this feature is to allow a user to move their licence to a different PC, in compliance with the Lighting Reality PRO EULA (End User Licence Agreement).

We understand that this feature may not be suitable for all companies due to restrictions by IT departments on how software is installed, licensed and used, so by default this feature will be disabled for all users. If you would like to take advantage of  the licence mobility feature please contact support@lightingreality.com with your name, email address and licence key to have this feature enabled.

To move a licence, first release the licence on the existing PC, by navigating to Help> Licence screen in either Roadway or Outdoor. Click the “Release Licence” button.

Install Lighting Reality PRO on the new PC and start Lighting Reality Outdoor or Roadway. When prompted enter the current licence key, and then click “Activate”. Licence releases and activations can only work when a PC is connected to the Internet, and all releases/activations are logged by the licence server for support purposes.

3.    Australia/New Zealand AS/NZS 1158  V Class 2022

Roadway has support for the AS/NZS 1158 V class standards. Use the Standards>Configure list to display or hide these new standards.

4.    Australia/New Zealand AS/NZS 1158  UWLR

Upward Waste Light Ratio (UWLR) calculation results have been added to Roadway for both the 3.1 standard and earlier 2005 P classes for AS/NZS 1158.

5.    Australia AS1158 staggered special case added

Staggered special case added to AS 1158 Roadway calculations.

6.    Glare class calculation (G Class)

Luminous Intensity Class (Glare class) calculation has been modified to use the definition in EN13201:2015, not EN13201:2003. The definition in Table A-1 of part 2 of EN13201:2015 now refers to Maximum luminous intensity at 70° and above, at 80° and above and at 90° and above. EN13201:2003 used the definition at 70°, at 80° and at 90°.
