"I learned that this limit is theoretical." So if i hooked them up like that is it theoretical falure or would it work just with a higher potential of falure in bad conditions? Or would it just not work at all?

There are several (lots, too many IMO) of examples of “working” LED Strip Lights with 200 - 300 Vdc wired circuits, but it’s done using “Circular Reasoning”. Just because it can be done doesn’t mean that it should, the Electrical Rating are there for safety reasons.
I haven’t built any high power COB fixtures but the “Other” Series / Parallel discussions may be an “holdover” from them. COBs often need Series wiring due to current / amperage requirements and higher operating voltage. LED strips are built a little different with different ratings.Horst wrote: ↑Tue Mar 09, 2021 9:25 pm@Popl111
Just wanted to show u second opinion. It’s funny somehow. In this Forum nearly everybody arguments for parallel. I read in another firing too, there everybody tells u ur led go to hell with parallel if ur temperature is not the same for every single one....
Both sides have their points and it’s Hard to rate the risks for myself too. My tendency is to do seriell and stay below 200v. U can always take two 120 instead of one 240 for example to make the whole thing smaller.
I respect this thing and install everything calm and carefully. I have good airflow too so it’s Never „wet“ in the room. And high ampere has its dangers to.....it’s a little dangerous no matter if parallel or serious when dealing with electricity.
Read many different opinions and build ur own. At the end it’s always ur own responsibility to decide.

What you describe here is Constant current control, this does no apply to Constant Voltage drivers unless you get an A or AB or constant power version, but not a B versionShimbob wrote: ↑Wed Mar 03, 2021 4:18 pmThey do this because they're designed to do it as part of being a LED driver. There's circuitry that monitors the output and adjusts the voltage to match what the LEDs want. The voltage the LED want is determined by the current.unclebilly wrote: ↑Wed Mar 03, 2021 4:59 amWhy will a constant voltage driver adjust its voltage down to 39? Is it only because there’s 10 strips and that will max out the current output and not allow it to reach 42 volts?
If you were to run one strip, yes it would fry but not because of the voltage, just the excess heat generated by the excess current.
