Where to find hlg240-1750 or 2100 ?? Are they the same as 240-15 or 240-20?

It seems like running 3 Vero 29 on hlg 240-2100 is about the best way to go. Any idea how many vf a 320 holds.

Thank you unfortunately I have to buy veros. $$$. But I you have been very helpful. That chart seems a little dated though. Any idea where I can find a newer one. To me it seems like Vero lend themselves to a higher drive current.

But watts do come into play?

Ok f-in awesome!

Series, but I've looked at the data sheets. For a Vero 29 and for a hlg 185, where does it say how many volts does a Vero 29 but out. I find vf of a Vero29@ different currents. But how does one find out how many vf a certain hlg 185 has at different currents? That file isn't working. Thanks.

Does a 185 run 4 Vero 29 @1400? Moreover does anybody know what I need to run 3 Vero @2000 ? A 185 or 240?

Wondering if hlg185-20 will run 3 Vero 29, or do I need a 240???

Any info on open frame? Why so cheap?

These seem cheap? Like 600w driver is 60 bucks. Is there something wrong with them? And what are the posts on the front of these?

Collect dust or combo circuit?

Just figured out combo circuit, and it might be a $40 dollar fuck up collecting dust as well.

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.

Ok thanks. I understand. So a combination circuit would work. I'm not going to ask ya to explain. But… What would you do with it?

As you can see I'm getting 2 different answers

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

Yes but a lpc150-2450 is a cc driver. If a Vero 29 has 39Vf can ya run 3 on it. Lpc150-2450 vdc is 31~62. Does vdc stay the same???

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.

Parallel. I think I'm going to try to get as close to 150w and see what happens to a single
