On 5 November 1999 AS/NZS 1158.3.1:1999 was published as a further revision to the Australian/New Zealand Public Lighting Code.  This standard introduces Category 'P' (Pedestrian Area) lighting which supersedes category B & C from AS1158.1-1986 and Minor Roads of NZS 6701:1983.  Accordingly the Spacing Graph Generator has been replaced by a Windows application known as the Pedestrian Area Lighting software.

September 1997
Release of the revised Public Lighting Code AS/NZS1158:1997 (in April 1997) has required changes to be made to the Luminaire Performance Assessment Software - Major Roads , the current version now being 2.01. The changes are quite significant with alterations and additions to the Light Technical Parameters (LTP's) in Table 2.1 of the Code.
July 1997
Two new photometric data conversion software programs have been added to the already extensive range of programs available. These programs convert between the B-Beta and C-Gamma versions of the popular IESNA format.
April 1997
Release of the revised Public Lighting Code AS/NZS1158:1997 (in April 1997) has required changes to be made to the SAASTAN -User Interface, the current version now being 3.84. These changes are quite significant with alterations and additions to the Light Technical Parameters (LTP's) in Table 2.1. You will have to obtain a copy of the Code to see how the changes impact on the work that you do.
April 1997
One of the new LTP's introduced in AS/NZS1158:1997 is the Upward Waste Light Ratio (UWLR). The SAASTAN- User Interface software now encorporates suitable calculations for each SAASTAN run carried out. However, if a more detailed report on the UWLR for a particular photometric data file over a range of upcast angles is required then use of the Upward Waste Light Ratio software will be necessary.
