Two Ecotech Radion gen2 $950 (mar manufacture date, purchased around april) will throw in AI light rail (36", works perfectly for a 48" tank). Also have a reef link for $100 with purchase of the lights. Decided to switch over to 48 giesemann infiniti fixture pr something similar (will trade if you have on).
These are the lights and rails over my 48" tank.
