What is a driver?
Other than the LED chips, the other major component of an LED light fitting is the driver (sometimes referred to as a PSU, control gear or ballast). This converts and smooths the incoming electricity supply (usually 230V AC across the EU) to fit the much lower voltage requirements of the LEDs. This component is where most failures occur in LED fittings - lifetime is generally governed by the quality of the sub-components (particularly capacitors) and temperature.
