Mean Well HLG-120H Model Encoding
The model number identifies the series, rated wattage, output voltage, and function type. For example, HLG-120H-24A identifies a 24V model with adjustable output, while HLG-120H-24B identifies a 24V model with 3-in-1 dimming. The fixed-output configuration uses no function suffix, such as HLG-120H-24.
Why Choose the Mean Well HLG-120H Series?
The Mean Well HLG-120H Series combines dual-mode constant voltage and constant current operation, high efficiency, active PFC, rugged metal construction, and flexible output-control configurations. Its IP65/IP67 options, fanless cooling, and 7-year warranty make it suitable for demanding indoor and outdoor LED lighting systems.
