Frequently Asked Questions
Can I use the HLG-120H-20B for dimmable outdoor 20V LED landscape lighting?
Yes. The HLG-120H-20B delivers 120W at 20V with dimming capability and carries an IP67 waterproof rating. This makes it ideal for outdoor landscape LED lighting where you need both full weather protection and brightness control, including pathway lighting, garden accents, and architectural wash lighting.
Is the HLG-120H-20B suitable for dimmable 20V LED sign backlighting in exposed weather?
Yes. With 120W at 20V, dimming support, and an IP67 waterproof rating, the HLG-120H-20B handles outdoor sign backlighting where brightness needs to change between day and night. The sealed aluminium housing withstands rain, dust, and temporary submersion up to 1 meter.
Can I use the HLG-120H-20B with a PWM or 1-10V dimming controller?
Yes. The HLG-120H-20B accepts dimming via 1-10V, PWM, and resistance signals. This allows integration with a wide range of dimming controllers for 20V LED fixtures while maintaining the IP67 waterproof protection. It provides up to 6A (120W) at 20V output.
How many meters of 20V LED strip can the HLG-120H-20B power?
The HLG-120H-20B provides 120W at 20V. Divide 120W by your strip's rated power per meter to find the maximum run length. For a strip rated at 14W/m, that is approximately 8.6 meters (120W / 14W per meter). Always check your strip's rated power per meter and stay within the 120W limit.
Can the HLG-120H-20B withstand heavy rain and temporary flooding?
Yes. The IP67 rating means the HLG-120H-20B is protected against temporary submersion in water up to 1 meter depth and is fully dust-tight. Combined with the -40°C to +80°C operating range and sealed aluminium casing, it handles harsh outdoor conditions including heavy rain, snow, and standing water.
What is the difference between the HLG-120H-20B and the HLG-120H-20AB?
Both offer dimming on a 120W, 20V, 6A platform. The key differences are that the -20B has an IP67 waterproof rating and fixed baseline output, while the -20AB has an IP65 water-resistant rating and adds a potentiometer for adjusting the baseline output voltage and current. Choose the -20B for fully exposed outdoor installations and the -20AB when you need both dimming and output adjustment in a sheltered location.
