LED drivers are modern types of transformers that also direct electric current (AC/DC).
It is important to pay special attention to the information provided about the connection!
How to calculate the required driver performance? The sum of the wattages of all powered bulbs must be at least 20% less than the wattage for which the driver is intended. Therefore, if 4 bulbs with a power input of 3W are connected to the driver, it is necessary to select a driver with a power input of 15W.
