Emergency light spacing

[horrorsix]

I was wondering if anyone knows the center to center spacing for the Lithonia ELM2 LED emergency light at a 20' mounting height?

I'd think the manufacturer could give you some recommendations. Initial thought is 20' seems rather high though. Just remember you'll need 1fc minimum along your egress path.

Yeah the regular lights with 9w bulbs show a center to center of like 23' at a 20' mounting height but there are nos specs for the LED's that high. I assume they would be the same but I'd like to see it in writing. Everytime I call Lithonia tech support I get an answering machine.
