Thanks for the replies everyone. To clarify Im talking about Dual Arc Lamps, Metal Halide and High Pressure Sodium tubes are combined into one glass. So it would seem Iâ??m not losing any of the red or orange just picking up blue to go with it. Just wondering if they would be better for veg and or flowering?? Iâ??m not worried about cost as much as I am about quality and yield. I will replace bulbs when need no matter what they cost me. Two 1000W bulbs will cost me $287, if I get 4 bulbs to switch out it will cost me like $350= 2 Sunmaster MH Conversion Lamp - 600W and 2 Sunmaster Super HPS Deluxe 1000W.:rasta:
