Frequently Asked Questions
Can I use the HLG-120H-24A for 24V LED strip installations in a covered patio or soffit?
Yes. The HLG-120H-24A delivers 24V at up to 5A (120W) and carries an IP65 water-resistant rating, which handles splashing water and dust in covered outdoor areas like patios, canopies, or soffits. For fully exposed locations with direct rain, consider the IP67-rated HLG-120H-24 instead.
Is the adjustable output on the HLG-120H-24A useful for fine-tuning LED brightness?
Yes. The built-in potentiometer lets you trim the output voltage and current, which helps when you need to reduce brightness slightly or match the driver to a specific LED load. The CC voltage range is 12-24V, giving you room to lower the drive level without an external dimmer.
Can the HLG-120H-24A power 24V LED modules in a commercial light box?
Yes. With 120W at 24V, it can drive a sizeable array of 24V LED modules for light boxes, menu boards, or display signage. The adjustable output lets you dial in the exact voltage to match your module string, and the wide 90-305VAC input handles most commercial mains supplies worldwide.
How many meters of 24V LED strip can the HLG-120H-24A handle?
Divide 120W by your strip's power consumption per meter. For instance, a strip rated at 10W/m would allow up to 12 meters (120W / 10W per meter = 12m). Always check your strip's rated power per meter and keep total load at or below 120W for reliable operation.
Is the HLG-120H-24A suitable for a damp basement or parking garage installation?
Yes. IP65 protects against low-pressure water jets from any direction and full dust ingress, which is more than sufficient for damp indoor environments like basements, garages, or wash-down areas. For locations with direct rain or potential standing water, the IP67-rated HLG-120H-24 or HLG-120H-24B would be more appropriate.
