I'm definitely in the LED camp. The light isn't natural, but like Ski, I like it better than fluorescent. One question: Do FWC/ATC still even offer an incandescent option? If they do, you might compare costs if you get the incandescent fixtures and add your own LED lamps. There are a few LED lamps out there that fit the 12 volt incandescent fixtures. Plus, you then have the option of keeping an incandescent bulb in one of the fixtures, if you want.
Our 08 FWC came with incandescent fixtures. I bought compatible LED bayonet mount bulbs and swapped out just one of the two bulbs in the interior lighting. So my fixtures can be super efficient when we use just LED or we can use some juice and crank up to max wattage. Generally LED is all we need. Swapped the porch light too, so we can just leave it on : )
