Frequently Asked Questions
Can I use the HLG-120H-C1400AB with a 1-10V dimmer for commercial LED downlights?
Yes. The HLG-120H-C1400AB supports 1-10V and PWM dimming signals, making it easy to integrate with commercial dimming controllers. It delivers 1400mA constant current across 54-108V at 151.2W, suitable for high-output downlights in retail, hospitality, or office environments where adjustable brightness is needed.
Is the HLG-120H-C1400AB a good choice for dimmable LED high-bay fixtures in a warehouse?
Yes. At 151.2W and 1400mA constant current, it can drive high-bay LED fixtures effectively. The dimming input allows brightness reduction during low-activity periods for energy savings, and the adjustable potentiometer helps fine-tune current to the specific high-bay module. The -40°C to +90°C range handles unheated warehouse conditions.
Can the HLG-120H-C1400AB drive LED grow lights with automated dimming schedules?
Yes, provided the grow light modules operate at 1400mA with a total forward voltage between 54V and 108V. The dimming input accepts 1-10V or PWM signals from grow light controllers, enabling automated photoperiod and intensity schedules. The 151.2W output provides enough power for a mid-size grow light panel.
How do I size my LED string for the HLG-120H-C1400AB?
The HLG-120H-C1400AB regulates current at 1400mA within a CC voltage range of 54-108V. Add up the forward voltages of all LEDs in your series string, and confirm the total falls between 54V and 108V. The number of LEDs depends entirely on each LED's individual forward voltage, so always consult the LED datasheet.
Can the HLG-120H-C1400AB withstand temperature swings in an uninsulated equipment shed?
Yes. It operates from -40°C to +90°C, so it handles both freezing winter conditions and hot summer temperatures in uninsulated sheds or equipment rooms. The IP65 rating adds protection against dust and water splashes common in such environments. The aluminium casing aids heat dissipation in warm conditions.
What makes the HLG-120H-C1400AB different from the C1400A and C1400B?
All three share the same 151.2W, 1400mA, 54-108V CC output and IP65 rating. The C1400AB (this model) offers both an adjustable potentiometer and a 1-10V/PWM dimming input, making it the most versatile variant. The C1400A has only the potentiometer adjustment. The C1400B has only the dimming input.
