Connecting 2 SANlight evo 3-100 with AC Infinity Controller 69 PRO

I'd send Ac infinity an email if I was you, just incase what you want to do doesn't work, no point spending cash unless it's guaranteed to do what you want.

I doubt that anyone would have same setup and would be answering questions here. Check your adapters slots and description. Worst case you can put both lights on analog timer and all problems sorted. I used pro69 for extraction, oscillating fan and humidity/temp controller, my mars lights were monitored manually .
