Best Cost-Effective Way to Power Egress Lighting for Warehouse?

[cryptonenologist]

Building out a TI in a 40k sq ft warehouse. Adding cleanroom suites. Warehouse has existing 277v high bays with individual motion sensors. Whoever built it wasn't worried about egress, if I cut power you're just in a giant dark shell. For the TI permitting, they wanted a photometric map of egress, so now I have a bunch of bugeyes covering the path.

Of course in a normal room, it would just be off the unswitched lighting circuit. But in this warehouse I've got 28 separate 277v breakers powering ~150 lights.

My main concern is, how to power them so they comply with code and actually work to provide coverage in the appropriate areas. Secondary is how to do this in a cost effective way, as before I did the design I didn't think about the cost of running power from that panel all over the warehouse when it currently only runs up to the 36' roof.

Bugeyes are cheap and easy to install / service. Why do something else?

I'm planning on doing bugeyes, my question is how to power them since what I've normally seen is off the area lighting circuit. Or are you suggesting 100% battery operated bugeyes with light sensor? I haven't seen those but it would make sense if they exist.

Look up Dual Lite's ELSS system.
I have used them on the last five projects and they are great.
100A power units you can place anywhere. They power very bright emergency lights and the exit lights.
One project had 11 power units that eliminated over 125 batteries strung out over three floors.

I've used Iota Engineering central inverters with low end, name brand LED wraparounds several times in warehouses. The wraparounds are at full output so each one usually covers a large area.
