#What kind of LED driver is this? I'm looking for a replacement with Zigbee.

Hey friends, I was looking for a LED panel in a very specific shape. Initially I was looking for one with Zigbee, but couldn't find anything in the right shape. So I just gave up, ordered this one and resorted to control it with a Zigbee switch module instead. So far so good. But now that I have the panel in my hands, I notice that the driver is just this extra device (see picture). Surely I'd be able to replace it with a Zigbee driver IF I could figure out what exactly it does. It only says "Output DC165-240V" and there are three wires going to the LED. It controls CCT (I think there are only 2 settings - warm and cold) and brightess in about 5 or 6 steps. So nothing fancy. There's no description anywhere on how exactly the controller operates, so I'm hoping somebody here could provide some information? Or do you think this is completely propriatary? Thank you!
See picture for the controller; this is the device: https://www.aliexpress.com/item/1005007242936654.html

Hello @regal fjord,
I personally have never seen this ->

Output DC165-240V
on an LED driver, so it is something odd I think.
LED's themselves need 2 or 3 volts each, so there is some series / parallel shenanigans going on there or possible some other power supply action.

Hey mate, thanks for reply! My assumption is that it simply keeps voltage same as input but converts to DC? So for my 230 AC (EU) it would output 230V DC? Would that make sense or is that too naive? But yeah, I couldn't find anything remotely similar at all on Amazon/Ali/Google

This is a high voltage current controlled LED driver. The output is "Output DC165-240V 220mA+-5%". Meaning that it will make sure that there will be 220mA of current as long as the output voltage is in the range of 165V to 240V DC. The output voltage will depend on the number LEDs, with LED voltage roughly around 3V, you need between 55 to 80 LEDs in series to make this work. As the exact voltage over an LED will depend on the type of LED used, the temperature and the current, it is likely that you have something like 65 to 70 LEDs in your 'lamp'. It will be difficult to find a Zigbee controlled driver with the same spec, as it is quite unusal one, Warning, these higher DC voltage (>60V) can be dangerous, so do not touch exposed wires!

I was going to mention the danger thing as well. 200ma at a 160DC can actually kill you going hand to hand.
