Best wire for lm301b QB build

I am doing my first build with 4 lm301b boards and heatsinks from Atreum Lighting. Driving it with a Mean Well HLG-480h 54A driver. Want a clean as possible build so using a 3 way junction box to split the power to the boards, running them parallel. Will this wire work to run from junction box to boards.
Power Cable LED Low Voltage Lighting Ul2464 18/2 Red & Black Pair 12 – 24 Volt Dc. This is 41 strand flexible wire and I know solid is recommended for connection at board so plan to attach a short piece of solid wire to end and cover the splice with shrink tubing.

I'm pretty sure that you'll need to use solid core wire unless you plan on tinning the wire ends. The push connectors need a solid wire for good contact. I also believe that the insulation on the wite you listed isn't rated for the 50+V the supply produces.

Was planning to connect a short piece of solid wire to the end to make the connection with the board.Think I found the wire that will work.
ALEKO LM15120FT 2 Core Electrical Wire Cable Conductor says 300v max

i've made 4 fittings with lm401b strips (QB22a). I found the best thing to do is just use the same wire you buy in long rolls for wiring houses. I use 1mm2 stuff - don't know what that is in AWG but it's good for 10 amps. just as long as it's hard drawn wire or solid core you're golden. don't use soft drawn wire like you're planning just buy hard drawn. Your plan to use soft drawn wire and solder a short length of hard drawn stuff on the end will probably work but man what a lot of labor. hard drawn wire is cheaper anyway. don't worry about the insulation, as long as it's got some kind of plastic sheath on it it will be fine, 50 volts is nothing.

@spirtwolf what's your location? My local Ace hardware store (Michigan USA) has a plethora of solid core wiring sold by the foot, all gauges and colors...Seems any Home Depot, Lowes, type store should have something suitable....

lol why would you want to do all the extra splicing and shrink tubing? Just get 18/2 wire. Stores like home depot sell this as Thermostat wire. They worked great on the Atreum 144.2 boards.
