Thermoplastic flexible nylon (TFFN) fixture wire is a coated wire typically run through raceways that is specifically designed for fixture wiring. It's primarily used in commercial applications to power hardwired light fixtures in ceilings and walls. It's more flexible than THHN building wire but less resistant to heat, and it is only available in limited gauges (18 and 16 AWG).
