Frequently Asked Questions
Can I use the HLG-185H-20 to power 20V LED strip lighting for an outdoor installation?
Yes. The HLG-185H-20 outputs 20V at up to 9.3A (185W) and carries an IP67 waterproof rating, so it can be fully exposed to rain and even temporarily submerged. Its aluminium casing and -40°C to +90°C operating temperature range handle demanding outdoor environments.
Is the HLG-185H-20 suitable for powering 20V LED modules in commercial signage?
Yes. With 185W at 20V output, the HLG-185H-20 can drive substantial runs of 20V channel letters, light boxes, or cabinet sign modules. Its wide 90-305VAC input handles varying mains supplies, and the IP67 rating makes it reliable in outdoor sign enclosures.
Can the HLG-185H-20 power 20V LED floodlights for building or area lighting?
Yes, as long as the total LED load stays within 185W. The constant-current operation with a CC voltage range of 10-20V provides stable output, and the IP67 waterproof rating and wide operating temperature range make it suitable for permanent outdoor floodlight installations.
How many meters of 20V LED strip can the HLG-185H-20 power?
Divide 185W by your strip's power consumption per meter. For example, a strip rated at 14W/m would allow about 13.2 meters (185W / 14W per meter = 13.21m). Always check your strip's rated power per meter and keep total load at or below 185W.
Can the HLG-185H-20 be mounted in a fully exposed outdoor location without additional weatherproofing?
Yes. Its IP67 waterproof rating means it is protected against complete dust ingress and temporary submersion in water up to 1 meter. It can be mounted directly outdoors without additional enclosures. The operating temperature range of -40°C to +90°C supports year-round use in most climates.
What are the differences between the HLG-185H-20, 20A, 20AB, and 20B models?
All four share the same 185W / 20V / 9.3A core specs. The base HLG-185H-20 has fixed output and IP67 waterproof rating. The -20A adds output voltage/current adjustment via built-in potentiometer (IP65). The -20AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -20B adds dimming input only and retains the IP67 waterproof rating.
