Ya so I just look at this and it says led power 1200w but average draw is 520w that’s so shitty that they can advertise it as a 1200w
G'day mate,
I'll agree with everyone here.
This particular brand won't keep up with HID at all. I personally have exactly the same series, as the one in your pic of the manual.
I bought the "900watt reflector series". To cut a long story short, 600watts of HID in a 4x4 totally smashes it. 400watts out does it as well, by a very obvious amount.
I think your decision to change to 1000watt HID in your 5x5 is a good one.
Even two 600's...? Personally i'd probably choose this, with 2 aircooled hoods.
7'ft of hight isn't a lot for a 1000watt HID, temperature would be a bit of a battle without using AC.
Apparently the new DE HID fixtures require a lot of hight as well, which mightn't suit a tent either. But i can't speak from experience.
If you'd like to use LED in the future, i'd definitely say save a little more money. Then buy one of the LED's suggested above.
Good luck with your decision, and enjoy the rest of your grow.
Peace.
