I am going through changing my fluorescent tubes to LED's in my basement where my layout is located and settled on 4000K LED's, but swapped panels from an opaque white to a clear frosted and like the effect; so you also have to consider whether the bulbs are going to be covered and, if so, with what type of panel.
If you go to the fluorescent/LED light bulb section of Lowes, most stores have a series of comparison photos in that area that show the difference in how various "K" values make the scene look.
Although the "color" or "K factor" of the light is important, you should also look at the number of lumens produced by each type of bulb. The LED's I bought are 1,750 lumens which was bright enough for my use.
