I will admit the "dark ceiling" effect can be take a little getting used to.
Last year I replaced the hall lights in my house with integrated LED fixtures. They're boob type lights, flush mount to the ceiling, with all the emitters pointing straight down.
I also put three of the same light type in my kitchen to replace the 4" fluorescent tube fixture that was in there.
I'm EXTREMELY happy with the change in that there's a lot more light, and much better quality, in the halls and in the kitchen, but the "dark ceiling" effect is there, especially in the kitchen. It's not remendous, but you really notice it when you open the cabinets.
