LED Drivers, COBs

[pupuniko]

Guys I've been researching for some days and have several questions about LED drivers. I'm going to get more lights step by step. At the moment I have 5x Citizen CLU048-1212. 2x 3500k, 2x 3000k and 1x 5000k. As for drivers I dont know what to get. I want to get around 60w from each of them.

Is it necessary to run them with constant current driver? What if I run them on normal switching power supply with Voltage adjustment?

For example power supply output is adjustable 36 volts (+/- 10% adjustable) and run COBs parallel. Set the output voltage on exactly 36 volts. Let's consider 2 possibilities:
1) power supply output power is the same as sum of 5x COB. In this case the problem may occur by thermal runaway. Or if one COB may gets damaged will the power will be divided to the remaining COBs or the COBs will only pull what their I-V curve dictates and it won't get any danger amount of Amps?

I just want to find any cheaper solution, Led drivers are kind of out of my budget

Thanks

And guys, if there is no way, I can get them work on normal power supply, can you tell me which LED driver will be best for 5x Citizen CLU048-1212? (want to get 60w from each of them)

Also, is it possible to run different kind of COB or strip light which isn't same volt / amps as CLU048 s? for example to get more powerful driver now and later if I add 24v LEDs to power CLU048s and new ones together on a single driver?

HLG-320H-36A. Wire them in parallel meaning run a wire from the positive wire of the driver to every positive of each COB and the same with the negative. That will get you 65w per COB about
