Frequently Asked Questions
Can I use the HLG-100H-42 to power 42V LED street or pathway lighting outdoors?
Yes. The HLG-100H-42 delivers 42V at up to 2.28A (100W) and is rated IP67 waterproof, so it can be mounted in exposed outdoor enclosures for street lights, bollard lights, or pathway luminaires. Its -40°C to +80°C operating range also handles harsh seasonal temperature swings.
Is the HLG-100H-42 suitable for powering 42V LED high-bay warehouse lights?
It can drive 42V high-bay LED fixtures provided the total load stays at or below 100W. The constant-current mode with a 21-42V range ensures stable output for consistent illumination, and the aluminium casing aids heat dissipation in warm industrial environments.
Can I run 42V LED signage modules from the HLG-100H-42?
Yes. The HLG-100H-42 provides a steady 42V output at up to 100W, which suits medium-sized LED sign cabinets and channel letter arrays. The IP67 waterproof rating allows it to be placed inside outdoor sign housings where moisture exposure is likely.
How many meters of 42V LED strip can the HLG-100H-42 support?
Divide the driver's 100W capacity by your strip's rated wattage per meter. For example, a 42V strip rated at 8W/m would allow up to 12.5 meters (100W / 8W per meter = 12.5m). Always check your strip's rated power per meter and keep total load at or below 100W.
Can the HLG-100H-42 handle fully exposed outdoor installations with rain and snow?
Yes. Its IP67 rating means the enclosure is dust-tight and can withstand temporary immersion in water up to 1 meter depth. This makes it suitable for fully exposed locations including rooftop fixtures, garden lighting, and installations subject to heavy rain or snow accumulation.
What are the differences between the HLG-100H-42, 42A, 42AB, and 42B variants?
All four share the same 100W, 42V, 2.28A core output. The base HLG-100H-42 has fixed output and IP67 waterproof rating. The -42A adds adjustable output via potentiometer with an IP65 water-resistant rating. The -42AB offers both adjustable output and dimming at IP65. The -42B provides dimming without adjustable output and retains IP67 waterproof rating.
