What is meant when the NEC references electric light circuit? Is this a reference to a lighting circuit or a fiber optic reference?

I think if it was in reference to a fiber optic then it would be in a section of fiber optic or it would state fiber optic. Without knowing the section I am guessing it means a lighting circuit. Is this referencing art 725?

I did a search of the phrase "electric light circuit" in the 2011 NEC and found no such phrase.

Sorry should have specified this is from Mike Holt's NEC volume 2. I just checked the NEC and it's not in there. Mike is referencing electric light and power circuits. It's NEC section 725.139(F). Here's the sentence from Mike's book, "Audio output circuits [640.9(C)] using Class 2 or Class 3 wiring methods [725.136 and 725.154] aren't permitted in any enclosure, raceway, or cable with conductors of electric light or power circuits."

It says just what it says. Don't mix your audio wiring with lighting circuits or receptacle outlet wiring. Run separate conduits for your

audio equipment and separate conduits for lighting and receptacle uses.
