Frequently Asked Questions
Can I use the HLG-120H-54AB with a 1-10V dimmer for 54V LED fixture brightness control?
Yes. The HLG-120H-54AB accepts 1-10V and PWM dimming signals, allowing smooth brightness adjustment of 54V LED fixtures via a wall dimmer or automation controller. The built-in potentiometer also lets you set the maximum output level.
Is the HLG-120H-54AB a good fit for daylight-harvesting LED systems in commercial spaces?
Yes. Its 1-10V/PWM dimming input can be driven by daylight sensors or building automation systems to reduce 54V LED output when natural light is sufficient. At 120W with adjustable output, it provides both automated and manual control over lighting levels.
Can the HLG-120H-54AB power dimmable 54V architectural accent lighting?
Yes. With 120W at 54V, built-in dimming via 1-10V/PWM, and adjustable output, it is well suited for accent and feature lighting where scene-setting and smooth brightness transitions are important. The adjustable potentiometer helps fine-tune peak output.
Can I pair with the HLG-120H-54AB to a smart-home system for scheduled LED dimming?
Yes. Most smart-home controllers and lighting hubs that output a 1-10V signal are compatible with this driver. You can automate brightness schedules for 54V LED fixtures while the built-in potentiometer sets the maximum intensity ceiling.
How many meters of 54V LED strip can the HLG-120H-54AB drive?
The HLG-120H-54AB delivers up to 120W. Divide 120 by your strip's wattage per meter. A strip rated at 12W/m could run up to 10 meters (120W / 12W per meter = 10m). Always check your strip's rated power per meter before finalizing the run length.
Is the HLG-120H-54AB rated for semi-outdoor locations like covered patios?
Yes. Its IP65 rating protects against dust and low-pressure water jets, making it suitable for covered patios, porches, or building overhangs. For fully exposed outdoor installations, the IP67-rated HLG-120H-54B with dimming would be a better fit.
