I changed all of my main lighting to 8 watt Thin lights and have been very happy with the results. I used an 8 watton each side of each fantastic vent and a third red/white in the front. I kept the original fixures for the sink light and for the dresser area. I put in a second switch on each and use a red LED board on the second switch and I use a stadand 1141 in one socket of the fixture and a white LED board on the the other. The bathroom has two 8w flourescents.
These all proved good light and use far less power. I also have a
12v plug in reading lamp with a gooseneck if I need more light. After that I would have to drag out my LED lanterns.
In any case, I am very happy with the flourescents.
I set my fixtures up for secondary red lighting for night work

, actually it helps prevent night blindness from bright lights, which is handy for either using the telescope or getting out the nightscope for watching wildlife (may try that outside of the RV park some day!

).
I definately recomend the modern lights. Installation was not difficult either, though I did find out how far "out of sqaure" the vent locations were relative the the interior seems.
