Frequently Asked Questions

Can I use the HLG-320H-20A to precisely tune the output for 20V LED architectural lighting?

Yes. The HLG-320H-20A includes a built-in potentiometer that lets you adjust both output voltage and current. This is particularly useful for architectural LED installations where precise color consistency requires matching the driver output to each LED module's optimal forward voltage within the 10-20V CC range.

Is the HLG-320H-20A suitable for 20V LED strip lighting in a large indoor commercial space?

Yes. At 300W and 20V with up to 15A, it can drive extensive runs of 20V LED strips for retail, museum, or lobby lighting. The adjustable output allows fine-tuning to compensate for voltage drop over long cable runs, ensuring uniform brightness across the installation.

Can the HLG-320H-20A power 20V LED fixtures in a manufacturing or workshop environment?

Yes. The IP65 water-resistant rating provides complete dust protection and resistance to low-pressure water jets, making it appropriate for workshops, factories, and light-industrial areas. The 300W capacity at 20V handles high-output task lighting and workstation illumination.

How many meters of 20V LED strip can the HLG-320H-20A drive?

The HLG-320H-20A delivers up to 300W at 20V. Divide 300W by your strip's rated wattage per meter to find the maximum length. For a strip rated at 15W/m, that would be 300 / 15 = 20 meters. Always check your strip's rated power per meter and keep the total load at or below 300W.

Is the HLG-320H-20A appropriate for installation in a dusty or sandy environment?

Yes. Its IP65 rating provides total protection against dust ingress, so it can operate reliably in sandy, dusty, or particulate-heavy environments such as construction sites, desert locations, or grain-handling facilities. For locations with water immersion risk, choose an IP67-rated variant like the HLG-320H-20 or -20B.
