How is the Corsair K65 LUX different than the k65??

Solution
The less expensive bit is likely sales related. The keycaps are taking their cue from the Strafe series. There's a passthrough USB port, and something in the internals is supposed to better support the controls over the RGB LEDs.

Slight upgrade really. From what I've heard you wont have to be plugged in to the same computer for your profiles to work, they expanded the onboard electronics to hold on your lighting patterns. Slightly less issues with the RGB's that the K65/70 were having. And the cosmetics coming from the Strafe line up and the passthrough port.
