Cool, same here!! Love that attitude man, one gets up the ladder, we all get up the ladder!

Are you using solid or stranded wire?

Right now that two inch connector is 16ga stranded. It's only spec'd for 18ga solid so I didn't want to try to cram 16ga solid in them. But I'm going to use both driver outputs to directly drive the strips with no jumper. I'll drill pass-through holes for the wiring in the middle of the strips and use short lengths of 18ga solid to the board connectors.

I'm curious as to what the voltage drop would be like on the 4ft strips using HLG-240H-48A driver to power 3 of the strips.

I'm not sure how I'll going to roll this grow. They're in the big tent for now.

Maybe ~1v drop between 25 and 85°C or ~0,5v at 50°C. The droop because of the strip length are negligible. They have thick copper layers, no comparison to 5m rolls of 12v adhesive LED strips at least as long as there is no serious temperature difference between the strips.
I've seen builds with 10 strips in parallel running well with no issues.

How's the grow going?

Hurry up and wait seems to be the order of the day. The Thai cross seedlings are chugging along but won't be ready to transplant for a while. And the G13 is stubbornly refusing to germinate. I've got something that looks interesting from Dave at Golden Coast Genetics that I'm considering dropping soon. It's a BOEL Skunk x JohnnyD Cambodian Thai. I'll give the G13 the benefit of the doubt for a few more days.
Would 6 of the single strips 4 foot give better photon coverage from multiple directions ?

What do you mean by multiple directions?

If you're referring to having more points of light dispersed across the canopy, then yes. And the cool thing about running the strips in parallel is that you can add strips very easily. It helps to understand that the voltage is relatively constant and the current can be adjusted within a specified range. Whatever current you adjust the driver's output to is shared equally by the strips. If you adjust the driver output to 10A and have 5 strips each strip will see 1/5th of 10A or 2A, 6 strips would see 1/6th of 10A or 1.67A each, and so on.

Just to add on. Each one of the FB24B has 288 diodes. Same as the QB288 but in a strip. 16S 18P.

Exactomundo, Eph3m3raL. Each of my 4xFB24B strip systems is the same diodes and diode count as an HLG550. So in essence, I'm running two 550s in a 4x4 area but will be able to run them softer and closer to the canopy in a scrog. Or I can reconfigure the lights to cope with an uneven canopy. For a DIYer or for someone who can't wait for HLG to restock it's a win.
HLG hit it out of the park with their systems. Beautiful, elegant, and efficient in design, and dead simple to assemble. They've taken all of the guessing out of the game and provided a turn-key LED light that's a winner. I'm sure that they're wishing production could keep up with demand!

Wonder how this would compare to taking 6 HLG 120 boards and running in 2x4 ..?

If you ran 3 strips in a 2x4 you would get 144 more diodes than 6 HLG 120 boards. I am planning to build a 3 strip for my mother plants using the HLG-240H-48A in parallel which will give me about 240W at 1667mA. You could use a different driver and get more power as well. The boards are tested at 2100mA I believe. HLG has a great product though if you are able to take the DIY route I believe these strips are a great option.

The FB24B is spec'd at 2240mA. Max is 3600mA. With three strips you could conceivably drive them to 10A with a 480H running wide open and be hitting 480W. That's the system I recommended to a friend because: A. You only need a voltmeter. B. You're unlikely to exceed the strip's rating. C. Easily expandable by adding more strips. D. Dimmable to 240W. You could actually run six strips on that driver and maintain 240W.

looking to replace HPS, either strips or COBs. leaning towards F series strips. could get them vertical in the corners of the tent also.

still waiting to see if multiple single samsung strips can deliver enough oomph to flower well..compared to panels
i just have not done that yet..but have made some custom strips and bars
.. have indeed acertained that the strips do well with veg and therycan get very close to the canopy because they are a not all
grouped tightly together..ie awesome coverage..dunno about
penetration..this pic just has them laid across the frame..

Well, if we call penetration the ability of the light to reach down under the canopy with sufficient energy to be beneficial, I think dispersed LEDs are a decisive winner over single point light sources. First, the inverse square law doesn't apply, as was corroborated by my and other's tests. Second, a dispersed uniform-intensity light source exhibits almost no shadows because light comes in obliquely from many directions. A good corollary would be a store with one big light in the middle or multiple smaller lights arrayed over the ceiling. The one factor missing in LEDs is the far reds that HPS has in abundance.
