The UV ledstrip are all driven by this board here:
From what I can see, it's very likely these leds are 12V UV strips, and it's a matter of identifying the pinout of the LED connectors to the board.
Then this board connects directly to the rest of the Spike system, so you instantly get native UV kit control. So with this board and proper wiring you could use the Pinstadium UV kit. Or build your own using cheap Aliexpress UV leds.
At least in theory.
[EDIT] Looking at the manual and available information: this board connects directly to Node 9, through CN14, which is a transistor driven output of node 9. This means it's simply a digitally controlled switch from CN14. This UV led board essentially converts 48V to 12V, and use this digital input to turn on/off the UV ledstrips, you can see on the board picture there are two identical section, one for each side. Frankly, I'm surprised Pinstadium could not figure it out and build a custom board.
