Frequently Asked Questions
Can I use the HLG-480H-24B for large-scale outdoor 24V LED strip lighting with dimming?
Yes. The HLG-480H-24B provides 480W at 24V (20A) with a 1-10V/PWM dimming input for brightness control. Its IP67 waterproof rating allows direct outdoor mounting even in locations exposed to rain, snow, or temporary water pooling, making it well-suited for building perimeter strips, parking structure lighting, or garden installations.
Is the HLG-480H-24B a good choice for powering 24V LED modules in a large outdoor sign?
Yes. With 480W of output at 24V and IP67 waterproofing, it can reliably drive high-wattage LED sign modules in fully exposed outdoor locations. The constant-current operating range of 12-24V accommodates module strings with varying forward voltage drops. The dimming input lets you reduce brightness for nighttime operation.
Can the HLG-480H-24B power 24V LED lighting in a commercial cold storage facility?
Yes. Its operating temperature range of -40°C to +90°C covers cold-storage and freezer environments. The IP67 waterproof rating protects against condensation and washdown moisture. At 480W it can supply substantial 24V LED fixture loads commonly used in walk-in coolers and refrigerated display areas.
How many meters of 24V LED strip can the HLG-480H-24B drive?
Divide 480W by your strip's rated wattage per meter. For instance, a strip rated at 10W/m could run up to 48 meters (480W / 10W per meter = 48m). A denser strip at 19.2W/m would allow 25 meters. Always verify your strip's rated power per meter and keep total consumption at or below 480W.
Can the HLG-480H-24B be installed in a below-grade vault or wet junction box?
Yes. IP67 means the enclosure can withstand temporary immersion in water up to 1 meter deep for 30 minutes. It is suitable for underground vaults, wet junction boxes, or any location where standing water may occasionally occur. The -40°C to +90°C range also covers extreme temperature environments.
