Hi iFly738,
The runway centre line lights before the displaced Landing Threshold serve as Approach Lights so will be 30m apart. The CL Lights after the landing threshold will be 15m apart.
One of the requirements is that the centerline lights are spaced 15m apart and the runway edge lights 60m.
Check with your Company Ops manual.
Ours permits us to use the full take of length, despite the lights being 30m apart initially - provided we can see the required visual clues using "Pilot assessment".
