Emergency Lighting Requirement

[faresos]

Hello everyone,

I was told by a code reviewer that we need to comply with NEC section 700.16 (Emergency Illumination) where it says:
"Emergency lighting systems shall be designed and installed so that the failure of any individual lighting element, such as the burning out of a lamp, cannot leave in total darkness any space that requires emergency illumination".
"Exception: Alternative means that ensure that the emergency lighting illumination level is maintained shall be permitted"

My question, how we are to comply with this requirement if we are using LED lights? will dual driver or even emergency battery pack within fixture located at exit doors will suffice this requirement?

I believe the "Exception" above might require us to have two emergency lights at adjacent location to get the light level required.

Thanks,

If you don't consider the driver to be part of the "lighting element," then any multiple-LED light should suffice.

The e lights are UL listed and meet appropiate standards to be able to be sold.

Different inspectors may interpret this requirement differently. Most realize that LED fixtures have multiple LED's.

And I don't consider a driver to be a lighting element, but some inspectors might.

But some fixtures are available with dual drivers for the inspectors that require them. And if you have to, you can always use 2 fixtures to satisfy the most picky inspectors.
