Luminus CXM-32 Meanwell HBG Driver

Hi, I am looking to do a single cob build with the Luminus CXM-32 and a Meanwell HBG Driver attached to a circular heat sink. I am not sure if there is a Meanwell driver that can do what I want.

I would like to have it be dimmable with the ability to run it on a high max end. From what I have gathered so far the Luminus CXM-32 can run at a max 3,960ma and requires 50-56 volts. Could I get by with the Meanwell HBG-160-60B or would the 60 volts be too much? 2.6 amps seem like a good high end and the option to dim would allow it to run as cool as needed.

Sorry for the noob question, just not sure if this driver works at that voltage. Maybe there is a better way to go.

Thanks!

You should be fine using that driver, it's a CV/CC driver so as long as your below 60v and above 36v you're good.

"Should be". Sounds about as confident as I am lol

youre gonna need some serious active cooling at that wattage. driver on top of heatsink sounds impractical, usually those setups are lower wattage and passive cooling

I think I would max out at 2.1amps or around 100 watts. That seems feasible on a beefy heat sink no? The Migro 100 has a similar setup and I am trying to do something similar DIY.

What about the 60 volts, is that ok for the CXM32?

Thanks in advance.

Possibly I should just go with the heatsink on the side? The Meanwell ELG-150-C2100A seems like a pretty good option for that

You could mount the driver outside the tent(remotely) and connect the COB using longer dc wires to avoid additional heat on the heatsink. A 93% efficient 150w driver means 11w pure heat and connect them directly to the heatsink will vause higher case temps.
Also the driver could be damaged if the heat goes into the driver.

And about the 60v. The driver CAN deliver up to 60v but the CXM32 TAKES only 54-55v at max. current.(2,6A or 2,1A)
To see 60v you need at least a 5 or 6A driver but since they only have 2.6 or 2,1A(HBG/ELG) it would be fail safe and you don't need to worry about too high voltage.
If you connect LED's directly to CV/CC drivers the driver is switching to constant current mode. The COB only takes as much voltage as needed depending on current flow.
