Frequently Asked Questions
Can I use the HLG-480H-54B for outdoor 54V LED lighting with dimming control?
Yes. The HLG-480H-54B outputs 54V at up to 8.9A (480W) and includes a 1-10V/PWM dimming input. Its IP67 waterproof rating allows fully exposed outdoor mounting, making it ideal for streetlights, parking lot fixtures, or building perimeter lighting that needs brightness control.
Is the HLG-480H-54B suitable for powering outdoor 54V LED signage?
Yes. With 480W at 54V and IP67 waterproofing, it can power large outdoor sign cabinets or monument signs using 54V LED modules. The dimming input lets you lower brightness at night for energy savings without needing a separate weatherproof dimmer enclosure.
Can the HLG-480H-54B drive 54V LED floodlights for outdoor area lighting?
Yes. The 480W output and constant-current operation with a CC range of 27-54V make it capable of driving high-power 54V LED floodlights. The IP67 rating and -40°C to +90°C operating range mean it can be installed alongside the floodlight in exposed outdoor locations year-round.
How many meters of 54V LED strip can the HLG-480H-54B support?
That depends on the strip's rated power per meter. The HLG-480H-54B supplies up to 480W at 54V. For a strip drawing 14W/m, you could run about 34 meters (480W / 14W per meter = 34.3m). Always check your strip's rated power per meter and keep total load at or below 480W.
Can the HLG-480H-54B withstand harsh outdoor weather including rain and freezing temperatures?
Yes. The IP67 waterproof rating means it can handle temporary submersion and sustained rain exposure. It operates from -40°C to +90°C, covering extreme winter cold and summer rooftop heat. No secondary weatherproof enclosure is needed for exposed mounting.
