Frequently Asked Questions
Can I use the HLG-320H-54 to power 54V LED strip lighting outdoors?
Yes. The HLG-320H-54 outputs 54V at up to 5.95A (320W) with an IP67 waterproof rating, making it suitable for outdoor 54V LED strip installations exposed to rain, snow, or moisture. The -40°C to +90°C operating range covers extreme climates.
Is the HLG-320H-54 a good driver for 54V LED street light or parking lot fixtures?
Yes. At 320W and 54V, it provides enough power for high-output street light or parking lot LED fixtures. The IP67 waterproof enclosure handles direct rain and hose-down, and the aluminium casing dissipates heat in enclosed pole-top compartments.
Can the HLG-320H-54 drive 54V LED modules for large outdoor signage?
Yes. With 320W at 54V, it can power large sign arrays such as channel letters or illuminated cabinet signs. The IP67 rating and wide 90-305VAC input make it reliable for outdoor commercial signage in varying weather and mains-voltage conditions.
Can I use the HLG-320H-54 for 54V industrial high-bay LED lighting?
Yes. The 320W capacity handles high-bay fixtures operating at 54V. The constant-current mode with a CC range of 27-54V adapts to the fixture's voltage requirements. The IP67 rating also allows installation in industrial environments with dust, moisture, or wash-down procedures.
How many meters of 54V LED strip can the HLG-320H-54 power?
Divide 320W by your strip's rated power per meter. For example, a 54V strip at 8W/m would allow up to 40 meters (320W / 8W per meter = 40m). Always check your strip's rated power per meter and keep total load at or below 320W.
Can the HLG-320H-54 handle extreme weather — deep freeze or desert heat?
Yes. The operating range spans -40°C to +90°C, covering arctic cold through extreme summer heat. Combined with its IP67 waterproof enclosure and aluminium casing for heat dissipation, it is built for exposed outdoor installations in virtually any climate.
