I just purchased my first LIFX bulbs... a Z strip (experience version) and a BR30. Anything warmer than neutral (3500K) on the Z strip looks quite green rather than a warm white and does not look remotely close to the BR30 on the same setting. All three Z segments I attached to the controller seem to match reasonably well (i.e. all green).
It did a firmware update when I first installed today, though I did add 2 segments after doing the firmware update... which work fine after pressing the button on the controller.
