Time for an update.
Worked on the light last night. Trying to get my second set of drivers organized for the "Parallel" part of the build.
Got plugs onto the three HLG150H-48B's and also setup the fuses and resistors for the strings.
The empty spaces on here are for the controller power-bar (whichever one I end up buying) and the dimming controller module (again based upon whatever controller I buy)
I have some quick connects coming that will allow me to disconnect the strings from the board and also at the light. Once they arrive and I see that they will work, I'll get pictures of them up.
