Yes, I have a dedicated OS to control garden lighting, and some zones on my other 2 are also used to control lighting. All you need is a 24V AC relay per individual zone, which you connect in exactly the same way as a water solenoid, there are some details here: https://opensprinkler.com/using-24v-ac-relays-with-opensprinkler/
Make sure you choose a relay with enough current rating to switch the entire load……if you have 600W transformer @12V that’s up to 50 Amps !!!
Or break up the lighting into zones so you can use smaller relays, or even convert halogen into LED to reduce power consumption.
