@caretak3r you had mentioned running 16 of the s02 4s4p is there anyway you could show me how to do that kind of wiring I get parallel and series now but doing them both at the same time I can't find any info on how to do that

@MrTwist1 the 1.813 profile is actually better if you don't want to use a fan they come in at 112 cm2 per inch just enough to run passive I know this is kind of a dead thread but just in case you now ya know

without looking at your specific application, its pretty easy to understand

parallel = current splits (for equal loads)
series = voltage doubled (for equal loads)
always

lets imagine you have a 1000mA constant current source
so lets take 3V LEDs

2 in parallel = 3V, 500 mA each. total load 3V 1000mA
3 in parallel = 3V, 333 mA each. total load 3V 1000mA
4 in parallel = 3V, 250 mA each. total load 3V 1000mA

2 in series = 6V, 1000 mA each. total load 6V 1000mA
3 in series = 9V, 1000 mA each. total load 9V 1000mA
4 in series = 12V, 1000 mA each. total load 12V 1000mA

pretend that any of the loads above are one single load when you combine them

i.e lets put 2 of the "4 in parallel" in series
"3V, 250 mA each" in series with "3V, 250 mA each" is now 6V, 250 mA each

alternatively, lets put 2 of the "4 in series" in parallel

these are "12V, 1000 mA each" individually but when you put two in parallel they are now 12V 500mA each

i hope that helps! there are simple equations you could use to calculate the current of two different loads in parallel, but when they are equal its pretty straightforward

@shake&bake , I think Bobby_G explained it better than I could, however, if you still need clarification let me know and I'll give it a try. I ended up with influx L04s, but still don't have them setup yet.

Know this thread has been left for sometime. But reading it has given me some ideas.

Anyway I've been wanting to add some side light to my lower canopy and thought I'd have a go.

Mark from cutter has made up 2 of these hard strips for me running XPG3 3000K x 15 (S3 Bin I think) on each 26cm (10") hard strip and I put them on some unequal anodized channel 40mm x 25mm 3mm base.

For testing I ran them on a Mars Hydro 750ma driver I have, but these will be going onto my coralux unit driven by 48v 7.3A meanwell power supply and LDD boards so that I can drive each strip at a desired level.

I plan to put a couple of 40mm 12v fans on these to keep them nice and cool.

Testing without fans saw a top temp. of 50c after a couple of hours in a very still room of 20c. so well worth putting little fans on there as with the 120mm 1300rpm fan it dropped the temps to 27c.

Mark is kindly getting a mix of 2700 - 3000 - 3500k that I'll have mixed on these hard strips.
I'm also going to get him to make up hard strips mixing 400nm 430nm 450nm 620nm 660nm and 730nm... I'm hoping we can make these strips so that each range is addressable with the coralux for some real control.

So couple of photo's of what I've got.

Did that ship with the bars? That's pretty cool!
