Frequently Asked Questions
Can I use the HLG-120H-12 to power 12V LED strip lighting for a storefront?
Yes. The HLG-120H-12 delivers 12V at up to 10A (120W), which is well suited for 12V LED strip lighting in storefront window displays or facade lighting. Its IP67 waterproof rating allows outdoor mounting even in exposed locations.
Is the HLG-120H-12 a good fit for 12V LED sign cabinet lighting?
It is an excellent choice for 12V LED sign cabinets drawing up to 120W. The 10A output can drive multiple 12V LED modules in parallel, and the IP67 waterproof rating means the driver can be mounted inside outdoor sign enclosures without additional weatherproofing.
Can I use the HLG-120H-12 for 12V LED under-cabinet or display case lighting?
Yes. At 120W and 12V output, it can power substantial runs of 12V LED strip or puck lights for under-cabinet and display case applications. The wide 90-305VAC input accommodates most commercial mains supplies, and the constant-current mode across the 6-12V range ensures stable illumination.
How many meters of 12V LED strip can the HLG-120H-12 support?
Divide the 120W maximum by your strip's rated wattage per meter. For example, a 12V strip drawing 14.4W/m can run approximately 8.3 meters (120W / 14.4W per meter). A lower-power strip at 4.8W/m could run up to 25 meters. Always check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-12 handle outdoor installations exposed to rain and dust?
Yes. The IP67 waterproof rating means it is fully sealed against dust ingress and can withstand temporary submersion. Combined with the aluminium casing and -40°C to +80°C operating range, it is designed for exposed outdoor environments including coastal and industrial settings.
What are the differences between the HLG-120H-12, 12A, 12AB, and 12B variants?
All four share the same 120W, 12V, 10A core output. The base HLG-120H-12 has fixed output and IP67 waterproof rating. The -12A adds an adjustable output potentiometer but drops to IP65 water-resistant. The -12AB combines adjustable output with dimming capability at IP65. The -12B offers dimming without adjustable output and retains the IP67 waterproof rating.
