But what happens to vdc? Is it still 31~62, or is it like a lpc 150-500 (600) 150~300vdc. So volts don't drop on a constant current driver. Even though it's running at 600ma does the vdc stay at 31~62? I've been told a couple of different things.

The 2450 is a constant current driver. 62vdc X 2.450a = 151w
Since its a constant current driver, you would divide 62/4 for voltage per string and 2.450/4 dor current per string to get the numbers of each string in paralell.

Thanks it's that + or - part that is needed
So max Vf is 13 on a string of 4???

Both are CC drivers. The higher current drivers are generally intended for running parallel circuits and higher voltage is intended for running series circuits but the way the current or voltage is split depends on the wiring not the driver. You could run a combination circuit where both the voltage and current was split, but a simple parallel circuit will split the current and a series will split the voltage.

Like you mentioned in your original post you can run a parallel circuit, but you will be leaving a lot of voltage untapped with CXB and will be using just over half the wattage. It will make the driver a bit less efficient... you can check the datasheet to see what efficiency you will get from running the driver at around 60%.
If for some reason you were going to use Vero 18s, since they only use 30-31 volts then you could run a combination circuit and get the whole 150 watts out of it.
Or you can do what I did when I made a similar mistake and leave it sitting on the shelf to collect dust

Perfect, run first parallel 1225ma on two then two in series, basically. I'm new to this and this site. I've posted this problem on several threads for over a day, your the first to give correct answer.

Ha! That's what I did with mine.Like you mentioned in your original post you can run a parallel circuit, but you will be leaving a lot of voltage untapped with CXB and will be using just over half the wattage.

Yes, that would work with Vero 18, you would be running 4 of them each at about 37 watts. You would split the + lead in two, each wire going to a cob, then a wire between each of those and the next two, then the wires coming off the second cob are joined together contacting the - lead.
But you have to consider whether it's worth it to use Vero 18s if that's not what you intended to begin with.

Collect dust or combo circuit?

Too bad we can't pool our our leftovers and mistakes here. I have enough bits, self tapping screws, hookup wire, grommets, pots, lever nuts, and mean wells for two more lights. I'll never use it.
