Find the right driver for your LED lighting project
⚡ Series vs Parallel
Series: LED boards are chained end-to-end. Voltages add up — total voltage = Vf × number of boards. Current stays the same throughout. Most common for LED engines.
Parallel: All boards share the same voltage rails. Total voltage = Vf of one board. Current multiplies. Used when all boards have the same Vf.
🔢 Forward Voltage (Vf)
The voltage drop across a single LED board when it's running at its rated current. Find this on the LED's datasheet — it's typically listed as Vf or Forward Voltage.
Common values: single LED chips 2–4V, high-power LED boards 9–54V depending on how many LEDs are on the board.
🔌 Drive Current
The constant current the driver delivers to your LEDs. This must match the rated drive current of your LED boards. After entering your voltage, the dropdown automatically shows only currents available from compatible drivers.
Selecting All currents shows every compatible driver regardless of current.
📊 Reading Results
Output Voltage — the range the driver can deliver. Your total LED voltage must fall within this range.
Output Current — the constant current the driver provides to your LEDs.

💡 Dimming Options Explained
Note: some drivers support multiple dimming methods. Always check the datasheet to confirm wiring requirements.
