What it boils down to is this: if you know which type of LED you will be using in your application, you can select the right driver by its operating window. Divided by the LED's 3.5V forward voltage, this means you can connect a maximum of 20 LEDs (instead of 30). B If the 30 LEDs are more important than Get the datasheets of both LED and LED driver and do the Voltage-Current-Wattage check. Voltage-Current-Wattage checkFrom the LED's and LED driver's datasheet, dig up the following data: LED: forward voltage Figure 1 - Operating window If you are scratching your head when hearing this term and seeing the diagram above – DON'T PANIC!
