Replacing my 600w hps with CBX3590 Cobs. Need help!

[bicit]

WOW... I have ordered already... 16 CXB 3500 72V...
Did I do something wrong? 4x (edited) MW 185-700c mA won't push them?

You should be good to go. Make four bars and distribute the light as evenly as possible. Should make a good lamp.

ETA: Or copy cat @REALSTYLES , that's a good one to emulate.

Just read REALSTYLES thread and you can see his design for the same setup. Btw You will get something like 870 ppfd in a 5x5 tent

Two lamps at full chat? Right?

Sorry,

I calculated what you bought the 16 cxb 780.8 dissipated ,if you tell me what's the area in fleets or m2 I can calculate what you need to cover it well.

The new room is huge something like 9x9ft but the tray i will build is 5x3 ft.
In a corner to use the reflection of the walls.

780.8w/16ft^2=48.8(w/ft^2)
48.8(w/ft^2)*0.55(est cob effecincy)= 26.84parw/ft^2
26.84(parw/ft^2)*4.8umol/s*10.7m^2=1378.50umol/s/m^2, or PPFD.

I'm really out of it so double check my units

5x3 is Near the same area than 4x4 so like I said something around 1400 ppfd but if I was you I will make a 5x4 area for the ideal 1050-1100 ppfd, sounds ideal for me!

Rough calculations based on some assumptions. Mostly a bit of educated guesswork.

These cobs produce good herb
