Our purpose in going with LEDs had nothing to do with boon docking and everything to do with how hot those fixtures get. There is a light right above the couch. If the light is on and we sit on the couch you could feel the heat radiate off of the fixture. My wife would not leave them on if we were not in the camper.
We got the cheap e-bay replacement bulbs and couldn't be happier. Beware, you can buy from online retailers, but you will pay anywhere from $3-$12 each. I had to replace 14 bulbs. 15 from Ebay cost me $21.
