My apartment formerly had traditional track lighting, but now all that's left is a live end connector sticking out of the wall (not sure if it's H, J, or L standard); even the track itself is gone. I'm thinking of purchasing Ikea's "Termosfar" track lighting system to use at the same location but am not sure how to figure out what additional parts will be needed to install the low-voltage Ikea system into the existing infrastructure. Help! :-)
