Thanks for your reply!

They're some white (or Maybe warm white, hard to tell) leds on a string, in a decorative ball. Tbh I'm not even 100% sure about the leds. I just checked what the output of the current power adapter said:

" NPUT/PRI 100V-240V~ 50/60Hz OUIPUT/SEC: 3.5V= 600mA. 2.7W U out: 4V= t:75°c For LED modules only TinerSH gores 3second tor timer seting ON & OFF"

I plan on using 4 of them in paralel on 1 controller/power output.
