wiring cobs parallel

I am doing my first cob wiring

i want to go parallel [dunno if i can go series because that may alter the wattage i can end up with]

i am using nichia cobs and td holders and 20 ga solid wire..

thing is from what i know about parallel they are attached to each other and that means doubling the wire
up to pass on to the other ones..there is only one + and - on the holder

is this photo correct..?

***also is there another way i can wire it parallel by joining two reds and whites between cobs via marrettes and still remaining proper?***

they are 36 v cobs and the meanwell is a hlg-120-48a [which is constant current]

i need advice before i plug it in..again the + and - are very difficult to push a pair of wires into..

i feel i should/could be doing it another way

i would like to hook up 3 or [4 if i can]nichia j130b..at about 30 w each

a yes or no or diagram would help but words are ok

thanks

If i do not try to daisy chain them and just marrette the three reds and three whites to go directly from the driver to each cob
is that parallel?

the holders just don't enjoy me trying to push two wires in each + and - insert hole

what about just putting one wire into the holder and then 6 or 8 inches back from there a wire nut would tie 2 or more wires together,instead of trying to push both wires into the holders

This is also parralel.

Hope that solves your problem.

i have 5 pole wagos on my site that would make your life easy

never try to put two wires into any single terminal slot- theyre not made for that and youre asking for trouble

Or just cut out a little piece of your main lead, wrap a piece of another stripped wire around the spot, solder it, then bend it down and heatshrink it.

thanks AW..i do not solder well


thanks bob kits..yes i should get some wago's

but
is this way ok?

is it necessary to use the A version drivers for parallel so that you get the adjustable voltage so that you can limit it so that you don't get thermal runaway?

or can i also use the B version and the drivers max voltage?

I guess it'll work. It looks right. But that's a lot of wires crammed in that Nut.

Yeah that type of connection has been my bane

why do you say that? It's so simple...

It is easy, I just hate the cutting between lines.. To me I would rather cut them, strip and then heat shrink... But I continue to take forever doing is as you showed.. I'm sure there is an easy way other than some pressure on wire cutters spinning around till enough shielding is off to connect the wire... Idk maybe it's me

Heaven forbid - use wagos if not for safety then for sanity.

I soldered my connections between my COB's myself and used the wagos to make the connections inside the junction box, was not too bad and I had never soldered anything before in my life

Solder is the bees knees. Love it, but I'm too lazy for a whole light

Wasn't that bad to me and I had never done it before lol.......no fires or explosions so far I just wanted certain connections to be as solid as possible is all especially those that would be "exposed"

It's not that, just time consuming is all. Years of doing it makes me not want to

Dude.. you take the wire between your thumb and pointer finger and roll it across a box cutter. Then move your wire 2-3mm away and roll it again. Then take the blade and cut between the cuts and it just peels off.
