However, the council's transport group manager, Richard Saunders, is remaining steadfast the council is on the right track.
The council has been trialling new 3000-Kelvin lights in several South Dunedin streets since last year, as part of a plan to replace the city's 15,000 ageing and failing high-pressure sodium streetlights.
The project was expected to cost about $12million, up to 85% of which would be covered by the NZ Transport Agency.
Concerns have been raised about the potential impact of the 3000K lights on human health, wildlife and the night sky, and calls from some submitters for warmer, 2400K lights instead.
The council was yet to announce which company would install the lights, or exactly what - if anything - would change.
But, at yesterday's DCC public forum, Dunedin Dark Skies spokeswoman Kyra Xavia, renewed her group's call for a rethink.
Ms Xavia, who is also New Zealand's representative on the International Dark-Sky Association, told councillors the 3000K lights being trialled in South Dunedin were not ''fit for purpose'', and the rest of the city was now set to get the same.
The NZTA should ensure 2700K lights were the maximum allowed along state highways, and even lower Kelvin, warmer lights elsewhere in the city, she said.
If the city made the wrong call, by rolling out 3000K lights, it would be ''locked in'' for years to come, she warned.
''They are not the lights that Dunedin deserves,'' she said.
Cr David Benson-Pope, chairman of the council's planning and environment committee, responded by asking for staff to report back on the issues raised, which council chief executive Sue Bidrose said would follow.
However, Mr Saunders told the Otago Daily Times later yesterday the issues had already been well canvassed.
An announcement on the contractor to do the work was expected within ''a couple of weeks'', and there was no chance of a last-minute change to the types of lights being planned, he said.
''We're happy we've canvassed all those options as part of our business case, in taking previous reports to council.
''We still think we've come up with a really good balance between those aspirations and the traffic safety, and having a light that's fit for purpose on the network.''
