Using 48V 300W CV driver

[Skaumannen]

Hello

I got a few inventronics EBV-350S048SV and Hahga 300W 48v LED drivers for free that i would like to use for a flower light.
I am comfortable soldering and making a DIY light, but i am having difficulties pairing LED's to drivers, and not the other way around.
It will be used in a 3x3ft space, and i don't need to use the max power from the drivers. I have a suitable inrush current limiter available, so i can use 2x350W drivers to power the lights even if they only use 400W or less.

I am in Europe, so will have to purchase from a supplier that ships here.

Link to Inventronics spreadsheet:

EBV-350SxxxSV - Inventronics 350W Constant-Voltage IP67 LED Driver

The EBV-350SxxxSV series of constant-voltage, IP67 LED drivers that operate from 176-305Vac with a maximum output power of 350W.

www.inventronics-co.com

Hahga specs 48V constant voltage, max amperage 6.25A.
Does anyone have any suggestions on what would be a good fit for either of these drivers?

Since EBV-350S048SV driver is a constant-voltage (CV) driver with a 48V output and up to 7.3A of current. To use it effectively, you need LEDs or COBs that are:

• Designed for a 48V input voltage.
• Compatible with the driver's available current, ideally with an internal current regulation mechanism or through proper parallel wiring with current balancing.
  

For example COBs Designed for 48V:
Bridgelux Vero 29C SE 48V COB, Citizen CLU048-1212 48V

LED Modules with Built-in Drivers:
Samsung H-Series LED Modules

It seems like this is a pure CV driver, meanwells CV drivers are actually CV/CC drivers. Im not sure how this would affect the build.

This is the samsung led product simulator it may be usefull. Remember you could also use 2 x 24V strips in series.

Actually the engine simulator is probably better for you, its all the strips cobs and such. Maybe you can try cobkits web, he still has 48V cobs i believe.

Clu 1212 is 36V i believe. Its 12s12p. Youd want something starting with 18, 1812,1818 or clu1825 but always check the datasheets.

Thanks for the replys, doing 2x24V strips in series is what i would prefer, i was just not sure if that would work out ok.

What i have not really found out is what happens if i run say 5x clu1825 on one of the 350w drivers. It can output max 7,3A, will it then give 1/5 of the max amperage to each COB? So each COB is 1,46A and the driver runs at 100% load at all times?

Ive only dealt with cv/cc drivers, not sure how it would work with a pure cv driver. My guess is yes but i dont know the citi datasheet very well.

Do you have specific strips in mind?

It would depend on which specific clu1825, I'm seeing typical voltages of 51.1 and 52 at 2.25 amps. The data sheet with a typical voltage of 52 shows around .5 amps at 48v. Scroll down in the data sheet for a graph of forward current vs. forward voltage.
