Lumatek Duel ballast run 2 of the same spectrum lights at the same time. SO instead of buying 2 ballasts for 2 lights, only one duel ballast is required. See link:http://www.growlightexpress.com/gro...asts-13/lumatek-dual-600-watt-ballast-33.html. If anyone has any good or bad please let me know. As I said, one 600 W duel is about the same cost as 2- 600 W ballasts. I wonder if the energy consumption is the same too. Should be. One advantage is less ballasts and less wires.
