Attracive Deck Lighting/Outlets How?

Preparing to run lighting and outlets to an expansive and lovely deck under construction. I planned to use THWN/THNN in conduit attached to the bottom of the deck, but how can I make it look good, i.e. avoid exposed conduit above the deck surface? There will be receptacles as well as BOTH 12V LV lighting and a couple 110V lights on tall posts.

I have heard of using the posts as raceways for wiring, but can this be done to code, and how would you transition from conduit to the posts?

The deck is composite (trex) and the posts will either be trex (hollow center) OR specialty surface mount steel core posts with vinyl casing that go with vinyls rail system, OR 4x4 with vinyl casing. The type of post chosen will depend on the wiring options available.

Ideas? Must be code compliant.

I'm not sure I understand what you mean by that. Can you explain further or give an example?
Wiring in framing has to be 1 1/4 inch from the edge of the framing to ensure a screw/nail won't penetrate the wire. If it's closer then in has to be protected from 'physical damage.' I am uncertain what form this physical protection must take in your application.
Maybe do low voltage for the lights and regular 120V for the receptacles. Lot's easier to work with LV if you are doing deck lighting.

A link to one person's solution.
