Frequently Asked Questions
Can I use the HLG-100H-20A to power 20V LED strip lighting in a covered outdoor area?
Yes. The HLG-100H-20A delivers 20V at up to 4.8A (100W) and carries an IP65 water-resistant rating, so it handles splashing water and dust in covered patios, canopies, or soffits. For fully exposed rain installations, consider the IP67-rated HLG-100H-20 instead.
Is the adjustable output on the HLG-100H-20A useful for fine-tuning LED brightness?
Yes. The built-in potentiometer lets you trim the output voltage and current, which is helpful when you need to reduce brightness slightly or match the driver output to a specific LED load. The CC voltage range is 10-20V, giving you room to lower the drive level without an external dimmer.
Can the HLG-100H-20A drive 20V LED modules for commercial signage?
Yes. At 100W and 20V output, it can power 20V channel letters, light boxes, or cabinet sign modules. The adjustable output is an added benefit for matching the driver precisely to the module string voltage. Its wide 90-305VAC input handles most commercial mains supplies worldwide.
How many meters of 20V LED strip can the HLG-100H-20A handle?
Divide 100W by your strip's power consumption per meter. For instance, a strip rated at 14W/m would allow about 7.1 meters (100W / 14W per meter). Always check your strip's rated power per meter and keep total load at or below 100W for reliable operation.
Is the HLG-100H-20A suitable for a damp basement or garage installation?
Yes. IP65 protects against low-pressure water jets and 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 base model would be more appropriate.
