i found them in home depot in canada in the same isle with household extension cords and timers and a bunch of "make our own lamp" shit, light sockets, adaptors, plugins etc. and the Y ones come in two pieces, the Y part and then it screws into the other piece that allows you to plug into a regular power socket, now i just put one Y setup on a little 6 foot extension cord from hd they cost 3 bucks and have three plugins and a hole to screw into shit. the Y adaptor pieces cost 3.50 each here but i just screw them together. hope this helps-- so in total for one complete Y setup with power is like 9 bucks canadian plus a lightbulbs but i think i seen some american on here say they were like 2 bucks for the Y adapotor pieces. Peace Sirus.
