2-600's or 1000 hps

[Zandor]

HPS 1000 Watt (140,000 Lumens),
HPS 600 Watt (92,000 Lumens), x's 2 = 184,000 lumes
HPS 400 Watt (50,000 Lumens),
HPS 250 Watt (27,500 Lumens),
HPS 150 Watt (16,000 Lumens),

but wait there is more.........

Sorry dude but the math does not work like that. It power dude and power is log rhythmic not proportional. 92,000 is still 92,000 you can't add them up and say they share the same space thus give you double the results. 600w lights will still degrade just like any other bulb will. They still have the same par watt sorry but the math is solid and true.
You donâ??t need to move them and they will cover a good area and yes they put out less heat. If you deal with the heat the 140,000 lumens on a track mover is hard to beat.
