Replacing original LEDs with 1 W units on MK180

Dear Ladies and Gentlemen,

I have recently purchased an MK180 and would like to replace the original LEDs with 1W units per below specs (4 pcs. per channel if possible).
I am unfortunately unsure how to connect them and what I need for that. Ideally, the easiest way would be great to know :slight_smile:
Could you assist?

Forward Voltage 3,0 to 3,6 V
Power Dissipation 1,05 to 1,26 W
Forward Current 350 mA
