Guys i need help, i have 4 clu058 1825 c4 chips and i only have acces to the meanwell hlg120 series drivers.
I am thinking of using the MEAN WELL 320W 48V 0-6.70A SP320-48 driver to power 2 chips parallel,i know that if one fails the other will blow of too this way but i am willing to take the risk.Will it work? I can also buy this one MEAN WELL 150W 48V 0-3.20A SP150-48 to be safer.Open to any suggestions thanks.

From the data sheets it looks like running two cobs parallel could possibly be higher forward voltage than the sp320 can provide, even maxed out.
See figure 4.1
https://ce.citizen.co.jp/lighting_led/dl_data/datasheet/en/COB_5/CLU058-1825C4_P3704_0516.pdf
and
https://www.meanwell.co.uk/media/productPDF/SP-320-SPEC.PDF

I think there might be problems.

The sp150-48 only has a maxed out voltage of 52v so that wouldn't work with that much current.

The HLG120-54 would run one cob to 120w ish. That wouldn't be a problem.

Why cant you get bigger hlg series drivers?

thanks for the time corey, i see the problem with the voltage sortage of the sp320 .There are no hlg 120 or higher sold in my country that have more than 36v output and i dont want to go ebay, but i found this guy
MEAN WELL 480W 48V 0-11.0A SP480-48 and i think i can run all 4 chips in parallel,What do you think?

Yeah that should work, you would be running all 4 cobs at lower current so the voltage will be in range.

I have 9 of those cobs in 90cri. They are good. Make sure you give them enough heatsink.

look at the hlg120-1400. I think you can get 80w each running in series with this driver. I get 165 watts with this driver on the CLU058 3618.

You are talking about this driver..LED MEAN WELL HLG120H-C1400B 150W 54-148V, i think this is the one coreywebster first suggested, 1 cob per driver for more light output?

those open-frame drivers are less than ideal for our application for a number of reasons. lower efficiency, less suitable for humid/wet grow environments, less protection features than the HLG series, etc

it does have voltage adjsutment which is an easy way to avoid 'blowing your cobs' as you were concerned about. just set the voltage to an appropriate limit in the 52-55V range which will effectively limit current

more importantly, make sure your voltage is reduced to stay in the 'rated power' region, as these are only rated at 33% duty cycle at peak load, unlike an HLG, where ive never seen one that couldnt be run wide open

that works. -48A or -54B also works and are a little more bang for the buck (and foolproof at one properly sized cob per driver)
