Daisy and I have used LED's in our Dutch Star for about 3 years now. Good for camping with no electricity as they uses one tenth of the current as other bulbs. We replaced the halogens first as those we used the most. Then replaced the fluorescence's in two short fixtures. At the time the strips did not have fixture parts to lock them in place - like Garys does. There is no heat so the strips just lay on the plastic lamp covers. I paralled strips until I got the right amount of light for the area and what they are used for. We also changed out the bayonet type on the four lamps using that style.
They are very expensive so we did not go for changing the lamps that get only momentary usage. The primary purpose is for dry camping. I found the installation to be very easy - halogens very easy.
