Frequently Asked Questions
Can I use the HLG-120H-C350A to drive long series strings of LEDs for architectural cove lighting?
Yes. The HLG-120H-C350A outputs 350mA constant current with a CC voltage range of 215-430V, allowing very long series strings of LEDs. This makes it particularly well suited for architectural cove lighting, linear LED strips, or contour lighting where many LEDs are connected end-to-end. The adjustable output helps fine-tune current to the exact LED specification.
Is the HLG-120H-C350A suitable for driving LED modules in large-format backlit signage?
Yes. The high 215-430V CC voltage range allows you to connect many LED modules in series for large backlit sign panels without needing multiple parallel strings. At 350mA and 150.5W, it can handle substantial sign surfaces while maintaining uniform brightness across the entire string.
Can the HLG-120H-C350A power small LED arrays used in accent or display lighting?
Yes, though this driver is optimized for longer LED strings at 350mA. If your small LED array has a total forward voltage between 215V and 430V, the HLG-120H-C350A will regulate current reliably. For arrays with lower total forward voltages, a lower-voltage model in the HLG-120H-C series would be a better match.
Why does the HLG-120H-C350A have such a high output voltage compared to other HLG-120H models?
The HLG-120H-C350A is a constant current driver rated at 350mA, which is a lower current than its siblings. To deliver approximately 150W at a lower current, the voltage must be higher (Power = Voltage x Current). The 215-430V CC range means this model is designed for long series chains of LEDs rather than short, high-current parallel configurations.
What LED configurations work with the HLG-120H-C350A's 215-430V CC range?
Your LED series string's total forward voltage must fall between 215V and 430V. The exact number of LEDs depends on each individual LED's forward voltage. For example, LEDs with a typical forward voltage around 3.0V could be strung roughly 72-143 units in series, but always verify against the actual LED datasheet values.
Can the HLG-120H-C350A be mounted outdoors on a building facade for decorative LED lighting?
Yes. The IP65 rating protects against dust and low-pressure water jets, making it suitable for sheltered outdoor locations on building facades. The -40°C to +90°C operating temperature range and aluminium casing handle year-round weather exposure. For fully unsheltered mounting with direct rain, consider additional weather shielding.
What distinguishes the HLG-120H-C350A from the C350AB and C350B?
All three share the same 150.5W, 350mA, 215-430V constant current output and IP65 rating. The C350A (this model) has adjustable output via potentiometer but no dimming input. The C350AB adds both potentiometer adjustment and 1-10V/PWM dimming capability. The C350B has only the dimming input with no adjustment potentiometer.
