Number of strips/leds/watts required for a 3.5x7 growroom

[Kaduflyer]

It a parrallel driver
If you are getting 2 footer you need to wire to in series to increase the volt to 38.
Then each 2 strips in parrallel
So you need 16 strips to give 8 parrallel arms
That would give you upto 0.835 ma per strip
18 strips would give upto 0.744 ma per strip

Likewise eight or nine 4 footer would be the Same but just wire in parrallel
You could have 12 or 13 4 footers on a 320 watt driver.

The driver with the prefix A can be adjusted with a small Phillip's screw driver
The driver with prefix AB gives the option of attaching an external dimmer.

I would have two separate lights for convience but doesnt matter
You could have a 480 driver if all on the same frame but two 240s can be cheaper

Once again thank you so much, you've explained it in terms that a newbie like me can understand so for that I'm deeply grateful, I'll keep you all posted

In series.

Can I use 8 bridgelux in series in that same driver?

8x19.1v= 152.8v
And they have a max current of 1.7 amps

Would I have a safe setup if I do that x3 for a total of 24 strips?
