Frequently Asked Questions
Can I use the HLG-320H-54B to power 54V LED floodlights in a fully exposed outdoor setting?
Yes. The HLG-320H-54B delivers 320W at 54V and carries an IP67 waterproof rating, protecting it against temporary submersion and heavy rain. This makes it suitable for outdoor floodlight, area lighting, and facade installations with direct weather exposure.
Is the HLG-320H-54B suitable for dimming 54V LED high-bay fixtures in a warehouse?
Yes. The -B suffix indicates built-in dimming input compatible with 1-10V, PWM, or resistance signals, allowing integration with building management or occupancy-based lighting controls. At 320W output, it can handle high-wattage 54V high-bay fixtures.
Can I use the HLG-320H-54B for outdoor 54V LED signage installations?
Yes. Its 320W capacity at 54V can drive large sign modules or multiple sign cabinets wired in parallel. The IP67 waterproof rating and wide 90-305VAC input make it reliable for roadside or building-mounted signs exposed to weather and varying mains voltages.
How many meters of 54V LED strip can the HLG-320H-54B support?
That depends on the strip's rated wattage per meter. The HLG-320H-54B supplies up to 320W at 54V. For a strip rated at 16W/m, you could run up to 20 meters (320W / 16W per meter = 20m). Always check your strip's rated power per meter and keep total load at or below 320W.
Can the HLG-320H-54B handle extreme cold in a northern climate outdoor installation?
Yes. It has an operating temperature range of -40°C to +90°C, so it can start and run reliably in sub-zero winter conditions. The IP67 waterproof enclosure also protects against snow, ice melt, and condensation.
