An LED Driver takes AC (Alternating Current) and changes it to DC (Direct Current) which is how most LED bulbs work. In most of SERA’s LED bulbs, the LED Driver is in the back on the bulb. This is not the case with every bulb on the market. Some manufactures require you to use a separate one.
These separate LED Drivers usually also contain a Transformer, which takes the 240v mains down to 12v or 24v, which is how most LED bulbs are powered.
LED Drivers usually cost more.
