For sure, I have a few random blurple drivers too and they're nice to play around with. Helps being able to actually see and do some things instead of reading and picturing the end result, at least for me.
Finally someone who understands this and is also prepared to go thru the length of explaining it (im damn tired of doing it myself, so hats off
). All good advice although i think you mix up the terminology re pulling volts or current even though the procdeure of how to set up your meanwell A-type dimming driver is correct. Again, but in other words: When you set or dim the voltage you consequently set a max current per board/strip; as you increase current thru a board/strip the corresponding forward voltage of the device will go up. As the voltage is limited by the driver you get an upper limit of current per device connected in parallel; the voltage of the driver sets up how much current each of the boards can draw. I figured I was off somewhere in my attempt at trying to help. Thanks for dropping some more knowledge for us though. I feel I have a little clearer understanding of it now as well. As always, much appreciated.Finally someone who understands this and is also prepared to go thru the length of explaining it (im damn tired of doing it myself, so hats off
Some things to keep in mind (and as per the 185w driver mentioned in the example above): follow this procedure and setup your driver to 48V so that each strip can draw 1000mA. If you connect only one strip at these settings to the driver, and keep current dimming to max: your 1 strip will draw 1000mA only but your driver will still pull power/over 200w from the wall as its still outputting full current, only that your strup cant pull that much(this as per my own experience with meanwells but might work differently). So in this case, i order to not waste power allways use the Io adjust as your main dimmer, the Vo adjust is more for setting up your whole system rather than controlling light intensity. But one needs to remember that inpractice the forward voltage of a strip is really the forward voltage and all its connecting cables/wagos: if theres a difference in cable gauge or length, extra wago connectors or what not between the different strings (this especially relevant with daisy chaining on the dc side) then you might see unequal light intensity between your strips even though your driver draws the same ac watts. Its allways best, if you can, to make sure each string is the same length in wire and amount of wagos as the rest.
Looking back at this it feels like more than explaining and simplifying ive muddled it more....
Do what loco said, and youll be fine. But if you see that even by doing so some of the strips are less.intense than the rest, then increase the Vo dimming ever so slightly till theyre all the same. After that use the Io dimming.
Not off, the procedure for the Vo setup is perfect, although i look at light intensity rather than killawatt.
Those Push In connectors never ever let go if your wire. Wagos are superior for a reason.
they have some stuff let me find some links
These strips are very cheap but they seem to be obsolete stock, if you have a look at the specs they seem quite low; i saw 137lums/w stated on one. The problem is that they use max amps as test current which makes it a bit complicated to evaluate them. Running them a bit softer might get those values a bit higher but id still compare them to other offerings, bridgelux eb being the first one to come to mind.
I'm actually just not sure where to find them all but interested mostly on a kickass deal on something like the f or h strips. You guys wiring in parallel or series?

Thank you sir. All that makes sense to me.
This is what i was looking for , thank you sir! i know you get 300 questions a day, thanks for your time!Finally someone who understands this and is also prepared to go thru the length of explaining it (im damn tired of doing it myself, so hats off

Not saying they aren't superior, just 4x the cost and not needed unless you are planning to assemble and disassemble multiple times. If we are trying to be budget friendly which with the price of these strips I assume most of us are, then regular push connectors work just fine. The 4ft aluminum channel I posted for $1 shipped isn't the most superior heatsink either but is a hell of a deal for anyone pushing a lot of strips at low wattage.
im still thinking parallel with little fuses just to make it easy.
while i have you here , are them 4ft er's still available ? Thanks man
