I own the LF 3000K E series module. The tint was nice, but I got bored and decided to de-dome it. Now it's about 2400K as
@jon_slider shows in his line up shot. Still very nice for night time and indoor use.
I also ordered a custom programmable SingLED module from Tana with a Nichia 519A 5000K emitter. Tana felt the tint was so nice, he decided to add it to his line up of options going forward. He tried to convince me to leave it domed, but I still de-domed it. It is now around 4200K and one of my favorite drop ins to use because I like a bit of rosiness in my lights. If you're willing to spend a bit more for Tana's work and willing to wait a few weeks, I suggest you get one from him with the emitter of your choice.
As for aesthetics, I use the shrouded tailcap (Z68) with the hexagon-shaped head. To me, that head keeps the profile small and compact; the flats also act as an anti-roll feature. I can snap some photos if you'd like.
