Frequently Asked Questions

Can I use the HLG-120H-15B for dimmable outdoor 15V LED landscape lighting?

Yes. The HLG-120H-15B delivers 120W at 15V with dimming capability and carries an IP67 waterproof rating. This makes it ideal for outdoor landscape LED lighting where you need both weather resistance and brightness control, including garden paths, deck lighting, and water feature illumination.

Is the HLG-120H-15B suitable for dimmable 15V LED sign backlighting in exposed conditions?

Yes. With 120W at 15V, dimming support, and an IP67 waterproof rating, the HLG-120H-15B handles outdoor sign backlighting where brightness needs to change between day and night modes. The sealed aluminium housing withstands rain, dust, and temporary submersion.

Can I use the HLG-120H-15B with a PWM dimming signal for 15V LED fixtures?

Yes. The HLG-120H-15B accepts dimming via 1-10V, PWM, and resistance signals. This allows integration with a wide range of dimming controllers for 15V LED fixtures. The driver provides up to 8A (120W) while maintaining the IP67 waterproof rating that the adjustable AB variant does not offer.

How many meters of 15V LED strip can the HLG-120H-15B power?

The HLG-120H-15B provides 120W at 15V. Divide 120W by your strip's rated power per meter to get maximum run length. For a strip rated at 15W/m, that is 8 meters (120W / 15W per meter = 8m). Always check your strip's rated power per meter and stay within the 120W limit.

Can the HLG-120H-15B withstand submersion or heavy rain?

Yes. The IP67 rating means the HLG-120H-15B 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 coastal salt spray.

What is the difference between the HLG-120H-15B and the HLG-120H-15AB?

Both offer dimming capability on a 120W, 15V, 8A platform. The key differences are that the -15B has an IP67 waterproof rating and fixed baseline output, while the -15AB has an IP65 water-resistant rating and adds a potentiometer for adjusting the baseline output voltage and current. Choose the -15B for fully exposed outdoor sites and the -15AB when you need both dimming and output adjustment in a sheltered location.
