Depends on the KL1 really. The LS*-P's use hand-picked LED's so you have a great chance of getting a nice white one all the time. The KL1's are not hand-picked so you might get one that's whiter, or greener, or it might have purple in it. It really depends. My KL1 is pretty bright, but has quite a bit of purple in it (compared to my LSH-P). The way I see it, when you get a LS*-P, you're paying extra to be able to "choose" a whiter LED.
