There are 2 ways to go about wiring LEDs: series and parallel. In most cases, if you have a constant current driver, you’re going to want to wire them in series. If you’re using a constant voltage driver, chances are, you’ll be wiring in parallel. You may even need to combine both methods in order to hit a certain voltage or current to match to a particular driver (see my post on matching COBs to drivers for more info on this). This information applies to LEDs of all types, whether they’re COBs, boards, strips, or whatever.
