Stuck on wiring system

[LuLeta]

I am working on some archway lighting, after a finished install the contractor has changed his mind and wants all of the lights to come on at lux level 35 and half to switch off at 70 lux level via photocell.

I have wired the lights in a leap frog way as the lights are on both sides and the contractor wants a zig zag pattern when half are on.

My issue is I have 1 feed and no way of getting a new one. is this even possible or should I recommend a dusk until dawn photocell for one half and a time clock for the other?

first thing is to inform the muppet that the work will be chargeable. then enter a silly high price. that should change his mind.

The simple answer is that if he wants the 50% lighting to be split across the sides then you'll need two switched lines on each side. I'm reading it as though you've a run along each side, with each run only having one switched line ?
Assuming you've installed what was first asked for, then I'm with Telectrix - you are under no obligation to make changes to support something that wasn't in the spec you were contracted to provide, so pick a price that makes you happy and walk away if they don't want to pay it.

Any way of doing it with smart lighting?

Might be costly, but not as much as ripping it all out to start again.
