Frequently Asked Questions
Can I use the HLG-320H-42 to power 42V LED strip lighting outdoors?
Yes. The HLG-320H-42 outputs 42V at up to 7.65A (320W) with an IP67 waterproof rating. It is well suited for outdoor 42V LED strip installations exposed to rain, dust, or temperature extremes, with an operating range of -40°C to +90°C.
Is the HLG-320H-42 suitable for 42V LED high-bay or industrial lighting?
It is a strong choice for industrial and high-bay LED fixtures running at 42V. The 320W output handles large lighting loads, and the IP67 rating protects the driver in dusty, humid, or wet industrial environments where sealed electronics are essential.
Can I power 42V LED signage or billboard modules with the HLG-320H-42?
Yes. The constant-current mode with a 21-42V range ensures stable brightness across LED sign modules, and 320W is sufficient for medium to large signage arrays. The IP67 waterproof housing allows mounting the driver in exposed outdoor sign cabinets.
How many meters of 42V LED strip can the HLG-320H-42 drive?
Divide 320W by your strip's rated power per meter. For example, a 42V strip consuming 18W/m could run approximately 17.7 meters (320W / 18W per meter). A lower-power strip at 10W/m could extend to about 32 meters. Always check your strip's rated wattage per meter and stay within 320W.
Can the HLG-320H-42 be installed in a location prone to flooding or water exposure?
Yes. With its IP67 waterproof rating, the HLG-320H-42 is protected against dust ingress and temporary submersion up to 1 meter. The sealed aluminium casing makes it suitable for flood-prone areas, underground installations, or locations with frequent washdown procedures.
What are the differences between the HLG-320H-42, 42A, 42AB, and 42B models?
All four share 320W, 42V, 7.65A core specifications. The base HLG-320H-42 has fixed output and IP67 waterproof rating. The -42A adds adjustable output at IP65. The -42AB combines adjustable output and dimming at IP65. The -42B offers dimming without adjustable output and retains the IP67 waterproof rating.
