with two 600s your getting more points of light, and i believe its more energy efficient
12Kwatts = 12 100w light bulbs burning at once.
1K watt = 10 light bulbs burning at once.
Now, where is the
"savings"?
OK, I run 5x5 tents for a perpetual harvest with 1K digital ballasts and I can still "burn" my girls depending on what I'm running in that tent. I can reduce my wattage as needed and that is still reaching peak effect for exceptional outputs.
I have other area's that run 2 1K's on a "racetrack" (light mover) that keep my full size plant's at peak, no shadow.
The real point is what size area is he going to be working and the goal of that (or any) grow is to produce a premium product at the lowest cost.
2 600's in anything but a 4x8 is simply overkill in the cost to benefit equation !
Why? Because I can produce, on average, more dry product in 250 sq ft (5x5x

with 1Kw then I can in 350sq ft (4x8x

with 2 600w at a lower cost!
The method you use x the nutrients x the media, makes all the world of difference to the final quality, period.
I prep my own soils, split my grows 1/2 pure organic using my own tea formula's and half a mix of synthetic and organic alternating daily.
This comes from decade's of experience and experimenting. Keep DETAILED note's on everything you do and review them regularly!
And yes, Induction lighting is great! Initial cost is high and can be daunting to start-up grows.
If you can afford it - GO FOR IT!
I am slowly switching over and I LOVE the results so far!
Go forth and grow effectively !!
