Cree manufactures LED emitters, which flashlight manufacturers buy to build flashlights with. Cree doesn't manufacture flashlights.

The design concept for multimode flashlights is that LEDs are very flexible, and some folks seem to really like that. However some flashlight manufacturers seem to have realized that there's a market for simply-operated lights, and have come out with lights that can be programmed to use simple user interfaces (Hexbright, HDS), have simple UIs with programmable levels (Quark Tactical), or have UIs that can be used very simply (Maelstrom, EagleTac).

For myself, my EDC light has a reasonably complex UI (Quark Regular) but I've been really digging the twist-head mode change lights I have (Maelstrom, EagleTac).
