Frequently Asked Questions

Can I use the HLG-120H-C1050AB with a 1-10V dimmer for LED downlight brightness control?

Yes. The HLG-120H-C1050AB accepts a 1-10V or PWM dimming signal, making it straightforward to integrate with standard commercial dimming systems. It delivers 1050mA constant current across a 74-148V range, so you can dim high-power LED downlights smoothly while maintaining consistent color output.

Is the HLG-120H-C1050AB suitable for dimmable LED high-bay fixtures in a retail space?

Yes. At 155.4W and 1050mA constant current, the HLG-120H-C1050AB can power high-output LED fixtures used in retail environments. The built-in dimming input allows you to adjust light levels for different display areas or time-of-day schedules, and the adjustable output lets you fine-tune the drive current to the fixture's LED module.

Can the HLG-120H-C1050AB drive a series string of LED modules for channel-letter signs with dimming?

Yes, as long as the total forward voltage of the LED string falls within 74-148V. The driver provides regulated 1050mA constant current, and the dimming input lets you reduce brightness for nighttime operation or energy savings. The wide 90-305VAC input handles most commercial electrical supplies.

What dimming methods does the HLG-120H-C1050AB support?

The HLG-120H-C1050AB supports both 1-10V analog and PWM dimming signals through its built-in dimming input. It also has an adjustable potentiometer for setting the baseline output current and voltage. This combination allows both manual trimming and automated dimming control from a building management system or standalone dimmer.

How many LEDs can I run in series with the HLG-120H-C1050AB?

That depends on each LED's forward voltage. The HLG-120H-C1050AB operates in constant current mode at 1050mA with a CC voltage range of 74-148V. Your series string's total forward voltage must land within that range. For example, LEDs with a 3V forward voltage could be strung roughly 24-49 units in series, but always verify against the actual LED datasheet values.

Can the HLG-120H-C1050AB handle temperature extremes in an unheated outdoor sign cabinet?

Yes. It operates from -40°C to +90°C, which covers extreme cold in winter and heat buildup inside enclosed sign cabinets in summer. The IP65 rating also protects against dust and water jets, though the cabinet itself provides additional environmental shielding.
