Frequently Asked Questions
Can I use the HLG-185H-48 to power 48V LED strip lighting outdoors?
Yes. The HLG-185H-48 outputs 48V at up to 3.9A (185W) and carries an IP67 waterproof rating, making it well suited for outdoor 48V LED strip runs exposed to rain or standing water. Its aluminium casing and -40°C to +90°C operating range handle extreme weather conditions.
Is the HLG-185H-48 a good fit for 48V LED signage applications?
Yes. With 185W at 48V, this driver can power 48V channel letters, light boxes, or cabinet sign modules. The wide 90-305VAC input accepts most mains voltages worldwide, and the IP67 rating allows direct outdoor mounting without an additional weatherproof enclosure.
Can the HLG-185H-48 drive 48V commercial or industrial LED fixtures?
Yes. The 185W output at 48V is sufficient for medium-power commercial fixtures such as high-bay pendants, linear troffers, or architectural cove lighting that run on a 48V bus. Its constant-current mode with a CC range of 24-48V also accommodates fixtures with varying forward voltages.
How many meters of 48V LED strip can the HLG-185H-48 power?
Divide 185W by your strip's rated power per meter. For example, a 48V strip drawing 14W/m could run about 13.2 meters (185W / 14W per meter). Always check your strip's rated power per meter and keep the total load at or below 185W.
Can the HLG-185H-48 be installed in locations exposed to rain or temporary flooding?
Yes. Its IP67 waterproof rating means the enclosure is dust-tight and protected against temporary submersion up to 1 meter. It can be mounted outdoors without additional weatherproofing, in underground vaults, or in areas subject to washdown.
What are the differences between the HLG-185H-48, 48A, 48AB, and 48B models?
All four share the same 185W / 48V / 3.9A core specs and 228 x 68 x 38.8 mm dimensions. The base HLG-185H-48 has fixed output and IP67 waterproof rating. The -48A adds output voltage/current adjustment via built-in potentiometer and is IP65. The -48AB adds both adjustment and 1-10V/PWM dimming (IP65). The -48B offers dimming input only while retaining IP67.
