I would only use a sauna rated light fixture, ones for this height will have to be a filament bulb, and are often encased in glass. I would also use silicone cabling. LEDs don't handle heat very well, and most sauna ones are only rated for lower levels.
I would use the regular sauna vapour barrier too, and I would run a heat proof silicone cable for a safe distance, rather than a PVC or rubber one.
