Frequently Asked Questions
Can I use the HLG-120H-C350AB with a dimmer to control long LED string brightness in architectural lighting?
Yes. The HLG-120H-C350AB delivers 350mA constant current over a 215-430V range and accepts 1-10V or PWM dimming signals. This makes it ideal for dimmable architectural lighting with long series strings of LEDs, such as cove lighting, facade outlines, or decorative contour lighting where smooth brightness control is required.
Is the HLG-120H-C350AB a good choice for dimmable LED backlit sign panels?
Yes. The high 215-430V CC range allows many LED modules to be connected in series for large sign panels, while the dimming input enables brightness reduction for nighttime operation or energy management. At 350mA and 150.5W, it provides reliable constant current across the full string with smooth dimming response.
Can the HLG-120H-C350AB drive a linear LED array for retail shelf lighting with dimming?
Yes, if the total forward voltage of your linear LED array falls within the 215-430V CC range. The 350mA constant current output maintains even illumination along the full length, and the dimming capability allows you to adjust brightness for different retail displays or time-of-day schedules.
How do I determine if the HLG-120H-C350AB is compatible with my LED string?
Sum the forward voltages of all LEDs in your series string and confirm the total falls between 215V and 430V. The LEDs must be rated for 350mA drive current. The number of LEDs depends on each LED's individual forward voltage. The adjustable potentiometer also lets you trim the output if your string is near the lower end of the voltage range.
Is the HLG-120H-C350AB safe to install in a dust-prone industrial environment?
Yes. The IP65 rating means the enclosure is fully protected against dust ingress and low-pressure water jets. Combined with the aluminium casing and -40°C to +90°C operating range, it can withstand dusty, dirty conditions found in factories, workshops, and industrial production areas.
What are the differences between the HLG-120H-C350AB and the other C350 variants?
All HLG-120H-C350 variants deliver 150.5W at 350mA constant current with a 215-430V CC range and IP65 rating. The C350AB (this model) includes both an adjustable potentiometer and a 1-10V/PWM dimming input. The C350A has only the potentiometer for output adjustment. The C350B has only the dimming input with no manual adjustment.
