The K7 Twist, Pipeline Reflect + Raw, and the CBL 1 are especially good for lighting museums. The K7 as well as the Pipelines are really easy to hide so they doesn't distract from what is being exhibited, and if you are dealing with high ceilings, the CBL 1 can light up exactly the object of your choice in a pretty small spot from a long distance. See for some examples here;-)
