After reading all the above, it seems many are having trouble cause they add the GE Link Bulbs to switched sockets, thus cutting power from the bulbs Tx/RX and creating status issues when switch power is cut.
I think a great solution for an example like a large basement with mutiple rows of lights would be to remove the actual standard switch and hot wire so the sockets are always hot. Install the affordable GE Link Bulbs to each socket, inplace of the removed standard switch, install a ZWN-SC7 zwave scene controler which has 7 buttons that can be configured to turn the lights on to any configuration you want (ie row, cols, area, ect). The large button is also nice to turn all off.
Despite being a zwave device, via SmartApp the ZWN-SC7 buttons can be captured and are able to be processed to change of state of any or mutiple devices (zigbee included) with a press of a button.
