Frequently Asked Questions
Can I use the HLG-185H-42 to power 42V LED panel lights in a commercial ceiling grid?
Yes. The HLG-185H-42 delivers 42V at up to 4.4A (185W) with constant-current operation across a 21-42V CC range, which is well matched to 42V LED panel lights used in office and retail ceiling grids. The wide 90-305VAC input handles most commercial mains supplies worldwide.
Is the HLG-185H-42 suitable for powering 42V LED high-bay fixtures in a warehouse?
Yes. At 185W and 42V, it can drive LED high-bay luminaires in warehouses, workshops, or industrial spaces. The IP67 waterproof rating allows mounting in areas with dust, moisture, or washdown exposure, and the -40°C to +90°C operating range covers unheated or un-air-conditioned facilities.
Can the HLG-185H-42 drive 42V LED modules for outdoor area lighting?
Yes. With 185W at 42V and an IP67 waterproof rating, it reliably powers 42V LED modules in parking lot lights, security floods, or perimeter lighting. The aluminium casing withstands outdoor conditions, and the constant-current mode with a 21-42V CC range ensures stable LED drive.
How many meters of 42V LED strip can the HLG-185H-42 support?
Divide 185W by your strip's wattage per meter. For example, a 42V strip rated at 15W/m would allow about 12.3 meters (185W / 15W per meter = 12.3m). Always check your strip's rated power per meter and keep the total load at or below 185W.
Can the HLG-185H-42 be mounted outdoors without a secondary weatherproof enclosure?
Yes. The IP67 rating means it is fully dust-tight and can withstand temporary submersion up to 1 meter. No additional enclosure is required for rain-exposed outdoor installations. The operating temperature range of -40°C to +90°C covers extreme climates.
What are the differences between the HLG-185H-42, 42A, 42AB, and 42B variants?
All four share the same 185W / 42V / 4.4A core specs. The base HLG-185H-42 has fixed output and IP67 waterproof rating. The -42A adds output voltage/current adjustment via built-in potentiometer (IP65). The -42AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -42B adds dimming input only and retains the IP67 waterproof rating.
