Frequently Asked Questions
Can I use the HLG-120H-15A for outdoor LED strip lighting with adjustable output?
The HLG-120H-15A outputs 15V at up to 8A (120W) and features adjustable output via built-in potentiometer, but carries an IP65 water-resistant rating rather than IP67. It is suitable for sheltered outdoor locations such as covered patios, carports, or sign enclosures, but should not be exposed to direct submersion or heavy water jets.
Is the HLG-120H-15A a good choice for powering 15V LED channel letter signs?
Yes. The adjustable output lets you fine-tune voltage and current to match your specific LED modules, and 120W at 15V is enough for small to medium channel letter signage. The IP65 rating is adequate when the driver is housed inside a weatherproof sign cabinet.
Can I use the HLG-120H-15A for 15V architectural cove lighting indoors?
It works well for indoor architectural cove lighting using 15V LED strips or modules. The adjustable output allows you to dial in the exact current within the 7-15V constant-current range, which helps optimize brightness and efficiency for the specific LED load. Total load must stay at or below 120W.
How many meters of 15V LED strip can the HLG-120H-15A drive?
The HLG-120H-15A supplies up to 120W at 15V. Divide 120W by your strip's rated wattage per meter to find the maximum length. For instance, a strip rated at 8W/m would allow up to 15 meters (120W / 8W per meter = 15m). Always check your strip's rated power per meter and stay within the 120W limit.
Is the HLG-120H-15A weatherproof enough for a rooftop or exposed wall installation?
The HLG-120H-15A is rated IP65, which protects against dust and low-pressure water jets but not submersion. For a rooftop where the driver is in a ventilated enclosure or under a canopy, IP65 is generally sufficient. For fully exposed locations with standing water risk, consider the IP67-rated HLG-120H-15 or HLG-120H-15B instead.
What does the 'A' suffix mean on the HLG-120H-15A compared to the base model?
The 'A' suffix indicates the model includes a built-in potentiometer for adjusting output voltage and current. The base HLG-120H-15 has fixed output. The A variant also carries an IP65 water-resistant rating instead of the base model's IP67 waterproof rating. Both deliver the same 120W, 15V, 8A output at their default settings.
