Frequently Asked Questions

Can I use the HLG-150H-20A to power 20V LED strip lighting in a sheltered outdoor area?

Yes. The HLG-150H-20A delivers 20V at up to 7.5A (150W) and carries an IP65 water-resistant rating, which handles dust and low-pressure water jets. It is well-suited for covered patios, canopies, soffits, and similar sheltered installations. For fully exposed rain locations, consider the IP67-rated HLG-150H-20 instead.

Is the adjustable output on the HLG-150H-20A useful for fine-tuning LED brightness?

Yes. The built-in potentiometer lets you trim the output voltage and current without an external dimmer. The CC voltage range spans 10-20V, so you can lower the drive level to reduce brightness or match the driver precisely to a specific LED load. This is particularly helpful for signage or display lighting where exact brightness control matters.

Can the HLG-150H-20A drive 20V LED modules for large commercial signs?

Yes. At 150W and 20V, it powers a substantial run of 20V channel letters, light boxes, or cabinet sign modules. The adjustable output lets you dial in the exact voltage to match your module string. The wide 90-305VAC input handles most commercial mains supplies worldwide.

Can the HLG-150H-20A power 20V under-cabinet or cove lighting?

Yes. The 150W capacity at 20V is more than sufficient for typical residential or commercial under-cabinet runs. The adjustable output lets you reduce brightness to the desired level without a separate dimmer. Its compact 228 x 68 x 38.8 mm footprint fits in most ceiling voids or utility spaces.

How many meters of 20V LED strip can the HLG-150H-20A handle?

Divide 150W by your strip's power consumption per meter. For instance, a strip rated at 12W/m allows about 12.5 meters (150W / 12W per meter = 12.5m). Always check your strip's rated power per meter and keep total load at or below 150W for reliable operation.

Is the HLG-150H-20A suitable for a damp basement or parking garage?

Yes. IP65 protects against low-pressure water jets and dust ingress, which is more than sufficient for damp indoor environments like basements, parking garages, or wash-down areas. For locations with direct rain exposure or potential standing water, the IP67-rated HLG-150H-20 or HLG-150H-20B would be more appropriate.
