Usually yes, within the same circuit type, and each product page states what a head is compatible with. What never mixes is circuit type: a single circuit (3 wire) head will not run on three circuit (4 wire) track, or the reverse. Low voltage 48V systems are a separate standard again and work only with their own track and driver. If you are adding to an existing run, send us a photo of the rail and live end and we will confirm the match first.
