Frequently Asked Questions
Can I use the HLG-120H-54A to trim the output for 54V LED panels that need a precise drive voltage?
Yes. The built-in potentiometer lets you adjust the output voltage and current, which is useful when your 54V LED panel or COB module performs best at a slightly different drive point. The CC voltage range of 27-54V gives you a wide adjustment window.
Is the HLG-120H-54A suitable for indoor commercial LED lighting installations?
Yes. At 120W and 54V with IP65 water-resistant protection, it works well in indoor commercial settings like offices, retail spaces, or warehouses. The adjustable output helps you optimize brightness for different ceiling heights or fixture types.
Can the HLG-120H-54A power 54V LED modules for illuminated signage in a sheltered location?
Yes. The 120W at 54V output can drive LED sign modules, and the adjustable output lets you match the voltage precisely to the module string. IP65 protection is sufficient for sheltered or semi-outdoor locations such as building overhangs or covered entrances.
How many meters of 54V LED strip can the HLG-120H-54A support?
Divide 120W by your strip's wattage per meter. For example, a 54V strip rated at 15W/m would allow about 8 meters (120W / 15W per meter = 8m). Always check your strip's rated power per meter and keep total load at or below 120W.
Is the HLG-120H-54A suitable for damp or dusty environments like a workshop?
Yes. Its IP65 rating provides full dust protection and resistance to low-pressure water jets. This makes it appropriate for workshops, garages, laundry rooms, or food processing areas. For locations with direct heavy rainfall, the IP67-rated HLG-120H-54 would be a better choice.
