Frequently Asked Questions
Can I use the HLG-120H-12A for adjustable 12V LED strip lighting in a covered patio?
Yes. The HLG-120H-12A outputs 12V at up to 10A (120W) with a built-in potentiometer for fine-tuning voltage and current. Its IP65 water-resistant rating makes it suitable for sheltered outdoor areas like covered patios where it is protected from direct rain and standing water.
Is the HLG-120H-12A a good choice for 12V LED channel letter signs where output trimming is needed?
It is well suited for 12V channel letter signage where you need to adjust the output to match specific LED module requirements. The 120W capacity can drive moderate sign arrays, and the adjustable output lets you optimize brightness and current without external resistors.
Can I power 12V LED light bars in a commercial display with the HLG-120H-12A?
Yes. At 120W and 12V, the HLG-120H-12A can drive multiple 12V LED light bars in a display installation. The adjustable output is useful for matching different light bar specifications, and the wide 90-305VAC input handles most commercial power systems.
How many meters of 12V LED strip can the HLG-120H-12A drive?
The HLG-120H-12A provides up to 120W at 12V. Divide 120W by your strip's rated wattage per meter. For instance, a 12V strip rated at 10W/m would allow approximately 12 meters (120W / 10W per meter = 12m). Always check your strip's rated power per meter and stay within the 120W limit.
Is the HLG-120H-12A weatherproof enough for a semi-exposed wall-mounted installation?
The HLG-120H-12A is rated IP65, which protects against dust and low-pressure water jets. For a wall-mounted location under an overhang or soffit where it is shielded from direct rain, IP65 is typically sufficient. For fully exposed mounting with no shelter, consider the IP67-rated HLG-120H-12 or HLG-120H-12B.
What does the 'A' suffix mean on the HLG-120H-12A compared to the base HLG-120H-12?
The 'A' suffix indicates the model includes a built-in potentiometer for adjusting output voltage and current. The base HLG-120H-12 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, 12V, 10A output at their default settings.
