Frequently Asked Questions

Can I use the HLG-120H-48AB with a 1-10V dimmer to control 48V LED strip brightness?

Yes. The HLG-120H-48AB accepts 1-10V and PWM dimming signals, so you can pair with a standard 1-10V wall dimmer or automation controller to smoothly adjust 48V LED strip brightness. It also has a built-in potentiometer for setting the maximum output level.

Is the HLG-120H-48AB a good choice for smart-home or building-automation controlled LED lighting?

Yes. Its dimming input (1-10V/PWM) can be driven by most smart-home controllers or BMS systems that output a 1-10V signal. Combined with 120W at 48V and adjustable output, it gives you both automated and manual brightness control for 48V LED fixtures.

Can the HLG-120H-48AB power 48V architectural LED cove or accent lighting?

Yes. With 120W at 48V and built-in dimming capability, it is well suited for cove and accent lighting where smooth brightness control is important. The adjustable output lets you fine-tune the drive level to match the specific LED strip or fixture installed.

Can I use the HLG-120H-48AB for dimmable 48V LED signage?

Yes. The 120W output at 48V can drive LED sign modules, and the 1-10V/PWM dimming input lets you reduce brightness at night or during off-peak hours. This is useful for commercial signs that need scheduled dimming to comply with local lighting ordinances.

How many meters of 48V LED strip can the HLG-120H-48AB drive?

The HLG-120H-48AB delivers up to 120W. Divide 120 by your strip's wattage per meter to find the maximum length. A strip rated at 12W/m, for example, could run up to 10 meters (120W / 12W per meter = 10m). Always check your strip's rated power per meter before sizing.

Is the HLG-120H-48AB rated for semi-outdoor locations like covered walkways?

Yes. Its IP65 rating protects against dust and low-pressure water jets, making it suitable for covered walkways, porches, or soffits where it is not directly exposed to sustained rainfall. For fully exposed outdoor locations, consider the IP67-rated HLG-120H-48B with dimming.
