I'm thinking about upgrading to some 1000 watt ballasts and was looking for some suggestions. I am thinking I am going to go with the Sun light Super Sun II reflectors and was looking at the Sunlight budget grow II 1000 watt ballasts to go with them. I can get a MH/HPS switchable ballast for $5 more than just a regular 100- watt HPS, do you think its worth it even though I will most likely be using it just with HPS. Do switchable ballasts last as long? Anyone have any other brand/ model suggestions?
