Dimming LEDs has benefits in terms of energy savings, ambiance, and increased lifespan. The performance of dimming is primarily determined by the LED source and driver. LED sources can generally be divided into two categories: LED diodes only and LED diodes with a resistor.

Sometimes, LED sources are designed as modules containing DC-DC converters. However, if the LED source or module is composed solely of LED diodes, the standard dimming method is accomplished by adjusting the LED's current amplitude. MEAN WELL HLG family features current adjusting and is controlled by an external dimmer with a signal of DC1-10V or 10V pulse width modulation (PWM) or with a simple resistor.
