Frequently Asked Questions

Can I use the HLG-80H-42AB to power dimmable 42V LED strip lighting?

Yes. The HLG-80H-42AB outputs 42V at up to 1.95A (80W) and includes both a potentiometer for output adjustment and a 1-10V/PWM dimming input. This makes it ideal for 42V LED strips where you need smooth brightness control from an external dimmer or automation system.

Is the HLG-80H-42AB suitable for smart-home controlled 42V LED lighting?

Yes. The 1-10V/PWM dimming input can be driven by most smart-home lighting controllers and building automation systems. Combined with the adjustable output potentiometer, you get both preset tuning and dynamic brightness control for 42V LED fixtures.

Can the HLG-80H-42AB drive 42V LED architectural accent lighting?

Yes. At 80W and 42V with dimming capability, the HLG-80H-42AB is well suited for architectural cove lighting, wall washers, and accent fixtures. The adjustable CC range of 25-42V lets you match the driver precisely to your LED module's forward voltage requirements.

How many meters of 42V LED strip can the HLG-80H-42AB power?

Divide 80W by your strip's rated power per meter. For instance, a 42V strip consuming 10W/m allows up to 8 meters (80W / 10W per meter = 8m). Always check your strip's rated power per meter and keep total load at or below 80W.

What are the differences between the HLG-80H-42, 42A, 42AB, and 42B models?

All four share 80W / 42V / 1.95A core specs with a CC voltage range of 25-42V. The base HLG-80H-42 has no adjustment or dimming and is IP67 waterproof. The -42A adds output adjustment via potentiometer (IP65). The -42AB adds both adjustment and 1-10V/PWM dimming (IP65). The -42B adds dimming input only and retains IP67.

Can I install the HLG-80H-42AB in a covered outdoor patio or carport?

Yes. Its IP65 rating protects against dust ingress and low-pressure water jets, which suits covered outdoor areas where splashing rain and dust are present. For fully exposed installations, the IP67-rated HLG-80H-42 or HLG-80H-42B would be more appropriate.
