InTheShed Grows Inside & Out: Jump In Any Time
Yup. We're coming at it from several directions and they all converge on that 0.35-.040 watts per diode area. That's 7, 8, 10 strips for that 2x4 space. It's what PGR recommended, and the range most people choose.
Remember that 625 diodes range? I run 2100 in that space.
So, you're talking to a crazy person.
At $15-25 a pop, you should get enough strips to max out the driver. Now it's just a matter of crunching some more numbers - between F-series and H-Influx, and deciding what amperage to drive the strips.
A 240H driver supplies 250 watts. The strips run about 22-23 volts at the current you'll run, and the C1050 driver can supply 238 volts, so you can run 10 strips at 1050ma, or 8 strips at 1400ma (179 volts max).

At 1430ma, the L06 3500K is 5800 lumens at 32 watts. A 240H-C1400 can run 8 strips. 8 x 5800 = 46400 lumens - right in your ballpark.
They don't show lumens at 1050ma, but it's probably around 5100 at 23 watts, so with 10 strips, you'd get 51000 lumens.

Aaaaaaaah! I don't want to talk about drivers yet! Drivers are the easy part that I can understand: you're running x milliamps so you need x driver...I've get that part I think. Of course I have no idea how milliamps relate to anything on the strips and I'm pretty sure I don't want to. I also now know why most people don't build their own lights 
.
I thought everyone was recommending 3000K.
Was the difference in price between what you recommended yesterday coming in under $250 all in, and PGR's recommendations today coming in at $250 for just the boards, the F vs H series? If I spend the extra money for 10 H series boards vs 10 F series boards, what's the difference in price, lumens, and wall watts that will help me decide between the two?
As my friend Richard used to say...gak!

This is a lot lol !
Ok, here's the F-series datasheet.
https://static6.arrow.com/aropdfcon...dc55ced38/f-series_gen3_rev0.0_2017-01-05.pdf
You can go with any temp, but for now, as long as I already did the L06s in 3500K, I'll stick with it.
At 1120ma the F562Bs do 4400 lumens at 25.8 watts, so you can only get 9 on a 240H. 9x4400 = 39600 - kinda short.
They don't list the other current levels though, dammit, so we can't be sure, but it's probably 7 strips at 4800 lumens and 15 watts. 7x4800 = 33600. Whew, way short.
It starts to look like the H-Influx may be worth it.
Double check my numbers though.

LOL! The data sheet confirms your input numbers but you'll have to check your own math!
The H-series data sheet has the following:
L04 3500K is 4060 lux, 22.3 v, 22.3 w
L06 3500K is 5800 lux, 22.4 v, 32.0 w
Does that tell you anything?

Waaay too much work, so many possibilities, but it's pretty easy with strips, just get CV drivers at the correct voltage and calculate the current
Don't worry about those lumen number, just look at the number of diodes.
64 diodes vs. 88 diodes
L06 is the better priced unit, L04 runs cooler because of the fewer diodes, that's the reason they're slightly more efficient.
You don't driver them at 100%, but 50% - 75%.
I think they're supposed to stay above 80% of out of the box output after 5 years.
The strips have to be mounted on a heatsink. U-channels make fine heatsinks.
Prices at Digi-key for 560mm strips:
F-series - $ 17,38 (72 LM561c diodes)
L04 - $ 18,50 (64 LM301b diodes)
L06 - $ 24,51 (88 LM301b diodes)
General rules of thumb: 800 diodes per m2, driven at 50% - 75% of the max rating.
There's a difference between H-series and H inFlux, H-series are old strips with few LM561c diodes and H inFlux are new strips with many LM301b diodes.
Rule of thumb diode count for 2x4 (120cm x 60xm = 0,72m2) 0,72 * 800 = 576 diodes.
Cheap way - 1 lamp: 6x H inFlux L06 on a HLG 240h-24A, up to 75% of max (~280w AC) 528 diodes.
Path of full blast - 2 lamps: (2x) 4 H inFlux L06 on a 185h-24A, up to 88% of max (~230w AC, but keep them at 200w max) 704 diodes.

Now you got the recipe for some lights! Go shopping, it's still Black Friday!

What's a "lamp" all of a sudden? Don't start throwing new terms at me this late in the game
.So you're saying 6 L06 3000K strips at 75% is 280w at the wall, 528 diodes, or 8 L06 3000K strips at 76% is 200w at the wall, 704 diodes.
L06 3000K at 75% is 4,222.5 lux * 6 strips = 25,336 lux. L06 3000K at 76% is 4,278.8 lux * 8 strips = 34,230 lux.
8 strips @ $24.81 is $198.48. How am I doing so far? We're sticking with 3000K still yes?
...my brain hurts......cheerz...h00k...

......cheerz...h00k......
Sounds like PGR is suggesting two seperate fixtures in th second option. With 2 drivers each supplying 4 strips. (Lamp = fixture ?)
Anyways - this whole discussion has actually very nicely documented the two different approaches I mentioned earlier. It’s helping me understand it

Remind me of the two different approaches again? I'm getting lost in the weeds. Was it efficiency vs something?
Well yes, those who build for efficiency/with efficiency in mind (which means you pay a little more at build for more diodes but you end up getting more of the required kind of light power for the Watts you use - I think, and that’s trying to say it without using the tech terms, but learn them if you can ) ... and then those who build for max power from less diodes, which I don’t know so much about, but things run hotter.
I like more diodes because of the spread. But there’s equally good reasons to choose either option.
If you lay out the builds that Gray and PGR are suggesting, and look over what G said about lumens per watt in relation to how hard you drive the diodes, maybe you’ll see the picture I’m seeing. I’ve been wrangling the territory bit by bit for a little while tho ...
so, yeah. It’ll come - you do get it, I can tell

Now you are pulling legs again Shed. Order the dam thing now. You are talking about one dollar here and one dollar there. The difference is not that big. Tomorrow Samsung, Osram or Cree will have another super chip in their machines and then you got another variable to hesitate over. The most important thing of this is the driver. It's with that you power your future leds with, it will definetly survive your leds. If you get a MeanWell that is.

These wholesale companies rarely have sales....
A single unit that emits light and is plugged into an outlet
You basically make a lamp for each driver you use, so the wiring is on a single platform.
Yes
No
It's two lamps each with 4 strips, so the total intended max draw is 400w and yes in the high 70's % of max.
Don't worry about these numbers, check out PPFD measurements for QBs and such that use the same diodes to get an idea of the output.
Also these calculations aren't linear, so you have to know the curve, and I still haven't found any for H inFlux, only the diode itself.
Yep, sounds about right, then you just have to price in heatsink, drivers and bits.
If you're on a tight budget go for 6 strips, it's gonna be well nice for 2x4.
My dad has H inFlux 3000K in his shed, he refused the cold 3500K F-series. so they're going to be my veg light
