6 strips would be good for that size. make your fixture 24 x 24. 150W should be all the power you need for it.

Does the 150w mean the each strip is about 20 something watts?
If so 12 would give me 300 watts?

At 6.25 square feet, I'd shoot for 200w, or even a little more, just in case you can use it.

Assuming we are discussing the 2ft- F series, single row Samsungs, driven at nominal current, then yes....Volts x Amps=Watts
The single row F series is a 23v emitter. Take the V- 23V, multiply by 1.12A (the nominal current draw) = the W draw per strip....
If you provide higher current, Amps per strip, the Watts consumed will rise.

I’ve been reading up on this for days and I couldn’t figure it out. This has been the best answer I’ve seen by far. Thanks so much.

I started with the DIY LED videos on YouTube by Growmau5. I had a background in hobby electronics, so I guess I had an advantage, but learning the nomenclature for this stuff was necessary.
Glad to help.

yeah, roughly. BUT, IMHO 300W of Samsung Strips would be overkill. Check out my Black Gorilla grow thread - 150 watts in a 24 x 39 inch space. - roughly that same area as yours:

Using this math. Bridgelux EB forward V 22.1 max current 700ma. 22.1 x .7 = 15.47. So these strips are r15.5 Watts a piece. 10 would give me the 150 Watts I’m looking for?

EB forward voltage is 19.5 at 700mA pretty sure. You can use 3000k-3500k for both veg and flower

@700ma the Gen1 EBs are 22.7v, then Gen 2 has the 19.5v, so you are both correct.
Nothing wrong with mixing spectrum versions, but in my opinion it is unnecessarily splitting hairs, say in between 3000-4000.
I just use 3500K for everything, mostly because they have generally been much cheaper than the 3K or 4Ks.

I see, I didnt realize the gen1 were 22.7fv

So I’m thinking 12 of the Bridgelux 22.1 volts would give me roughly 185w. On to the driver. What values am I looking for or if anyone has a specific part number for a driver that would be great.
And one more. With 185w in my small tent with these types of LEDs what kind of results am I looking at? Not asking about yield but rather quality of light this set up will give my ladies.
