Frequently Asked Questions

Can I use the HLG-185H-54AWE to power 54V LED strips in fully exposed outdoor locations?

Yes. The HLG-185H-54AWE outputs 54V at up to 3.45A (185W) with an IP67 waterproof rating, so it can be mounted outdoors in direct rain, sprinkler zones, or coastal environments. The aluminium casing and -40°C to +90°C range handle extreme weather.

Is the HLG-185H-54AWE suitable for outdoor 54V LED signage or building facade lighting?

Yes. With 185W at 54V and IP67 waterproofing, it can power 54V LED sign modules, facade wash lights, or architectural accent fixtures mounted directly on exterior walls. The wide 90-305VAC input handles varying mains voltages across different regions.

Can the HLG-185H-54AWE drive 54V LED fixtures in harsh industrial outdoor environments?

Yes. The IP67 rating makes it dust-tight and submersion-resistant, while the -40°C to +90°C operating range covers freezing winters and rooftop-hot summers. It is well suited for loading docks, outdoor production areas, or equipment yards running 54V LED fixtures.

What distinguishes the HLG-185H-54AWE from the standard HLG-185H-54?

Both the HLG-185H-54AWE and the HLG-185H-54 share the same 185W / 54V / 3.45A output, IP67 waterproof rating, and identical 228 x 68 x 38.8 mm dimensions. The AWE suffix indicates a variant with additional regional certifications or compliance features, making it suited for specific markets or project specifications that require them.

How many meters of 54V LED strip can the HLG-185H-54AWE power?

Divide 185W by your strip's rated power per meter. For example, a 54V strip drawing 15W/m could run about 12.3 meters (185W / 15W per meter). Always check your strip's rated power per meter and keep total load at or below 185W.

Can the HLG-185H-54AWE withstand installation in wet underground vaults or flood-prone areas?

Its IP67 rating protects against temporary submersion up to 1 meter depth, so it handles brief flooding in light wells, underground vaults, or low-lying junction boxes. Combined with the -40°C to +90°C operating range, it covers most real-world harsh and wet installation scenarios.
