Frequently Asked Questions
Can I use the HLG-120H-36 to power 36V LED strip lighting outdoors?
Yes. The HLG-120H-36 outputs 36V at up to 3.4A (120W) and carries an IP67 waterproof rating, so it can be mounted in locations exposed to rain, snow, or irrigation spray. Its aluminium casing and -40°C to +80°C operating range handle harsh outdoor conditions year-round.
Is the HLG-120H-36 suitable for powering 36V LED modules in channel-letter signs?
Yes. With 120W at 36V, the HLG-120H-36 can drive a substantial array of 36V LED sign modules for channel letters, cabinet signs, or monument signage. The IP67 waterproof enclosure and wide 90-305VAC input make it practical for exposed outdoor sign installations across different mains voltages.
Can the HLG-120H-36 power a 36V LED high-bay or industrial fixture?
Yes. At 120W and 36V constant-current output (up to 3.4A), the HLG-120H-36 is well matched to medium-wattage 36V LED high-bay lights or industrial luminaires. The IP67 rating and wide operating temperature range allow installation in factories, warehouses, or covered loading docks.
How many meters of 36V LED strip can the HLG-120H-36 drive?
That depends on the strip's power draw per meter. The HLG-120H-36 delivers up to 120W at 36V. For example, a strip rated at 15W/m would allow about 8 meters (120W / 15W per meter). Always check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-36 handle freezing temperatures in an unheated outdoor enclosure?
Yes. Its operating temperature range is -40°C to +80°C, so it will start and run reliably in sub-zero conditions. The IP67 waterproof rating also protects against moisture ingress from condensation, ice melt, or direct precipitation.
What are the differences between the HLG-120H-36, 36A, 36AB, and 36B variants?
All four share the same 120W / 36V / 3.4A core specs and CC voltage range of 18-36V. The base HLG-120H-36 has fixed output and IP67 waterproof rating. The -36A adds output voltage/current adjustment via built-in potentiometer (IP65). The -36AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -36B offers dimming input only and retains IP67 waterproof rating.
