Frequently Asked Questions
Can I use the HLG-120H-20 to power 20V LED strip lighting outdoors?
Yes. The HLG-120H-20 outputs 20V at up to 6A (120W) and carries an IP67 waterproof rating, making it well suited for outdoor 20V LED strip runs exposed to rain or harsh weather. The aluminium casing and -40°C to +80°C operating range ensure reliable operation in extreme temperatures.
Is the HLG-120H-20 suitable for powering 20V LED modules in illuminated signage?
Yes. At 120W and 20V output, it can drive multiple 20V LED sign modules in constant-current mode across the 10-20V range. The IP67 waterproof rating makes it safe for mounting inside outdoor sign cabinets or other exposed enclosures without additional weatherproofing.
Can I run 20V LED flood lights from the HLG-120H-20?
Yes, as long as the total load does not exceed 120W. The HLG-120H-20 delivers 20V at up to 6A, which is enough for several 20V LED flood light fixtures in commercial or security lighting applications. Its wide 90-305VAC input handles both residential and industrial mains supplies.
How many meters of 20V LED strip can the HLG-120H-20 support?
That depends on the strip's rated power per meter. The HLG-120H-20 provides 120W at 20V. For example, if your strip draws 12W per meter, you could run up to 10 meters (120W / 12W per meter = 10m). Always check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-20 be installed in underground or submerged enclosures?
Yes. The IP67 waterproof rating means it is protected against temporary submersion up to 1 meter depth and is fully dust-tight. Combined with the sealed aluminium housing and -40°C to +80°C operating range, it handles buried junction boxes, below-grade vaults, and other wet environments.
What are the differences between the HLG-120H-20, 20A, 20AB, and 20B variants?
All four share the same 120W, 20V, 6A core specs. The base HLG-120H-20 has fixed output and IP67 waterproof rating. The -20A adds adjustable output via potentiometer with an IP65 water-resistant rating. The -20AB adds both adjustable output and dimming capability at IP65. The -20B offers dimming without adjustable output and retains the IP67 waterproof rating.
