Edge lighting
The longitudinal spacing of runway edge lights must be uniform and be:
(a) for an instrument runway, 60 m +0 / -5 m;
(b) for a non-instrument runway, 90 m ± 10 m, or 60 m +0 / -5 m if there is an intention to upgrade the runway to an instrument runway at some time in the future.
(c) for non-precision instrument runways intended to be used in visibility conditions of 1.5 km or greater, where existing edge lights are spaced at 90 m ±10 m, it is acceptable to retain this spacing until the next replacement or improvement of the edge lighting system. (This situation typically arises from an existing non-instrument runway being upgraded to a non-precision instrument runway, but without re-installing the runway edge lights to the 60 m +0 / -5 m standard.)
Centreline lights
Runway centreline lights must be located from the threshold to the end at longitudinal spacing of approximately:
(a) 15 m on a runway intended for use in runway visual range conditions less than a value of 300 m; and
(b) 30 m on a runway intended for use in runway visual range conditions of 300 m or greater.
Source: Australian Manual of Standards Part 139 - Aerodromes Chapter 9: Visual Aids Provided by Aerodrome Lighting. These [new] OZ rules are aligned closely to ICAO.
But let me pull out ICAO Annex 14, vol.1, section 5:
Edge: not more than 60m for instrument runways, and not more than 100m for non-instrument runways.
Centre 7.5m or 15m on cat III runways. 7.5m, 15m, or 30m on Cat II or other runways.
There, that should throw some light on the subject (groan).
