Frequently Asked Questions

Can I use the HLG-100H-20AB with a 1-10V dimmer to control 20V LED strip brightness?

Yes. The HLG-100H-20AB accepts 1-10V and PWM dimming signals, so you can pair with a standard 1-10V wall dimmer or automation controller to smoothly adjust 20V LED strip brightness. It also has a built-in potentiometer for setting the maximum output level.

Is the HLG-100H-20AB a good choice for smart-home controlled LED lighting?

Yes. Its dimming input (1-10V/PWM) can be driven by most smart-home lighting controllers or building automation systems that output a 1-10V signal. Combined with 100W at 20V and adjustable output, it gives you both automated and manual brightness control.

Can the HLG-100H-20AB power 20V architectural LED cove lighting?

Yes. With 100W at 20V and built-in dimming capability, it is well suited for cove lighting where smooth brightness control is important. The adjustable output lets you fine-tune the drive level to match the specific LED strip installed in the cove.

How many meters of 20V LED strip can the HLG-100H-20AB drive?

The HLG-100H-20AB delivers up to 100W. Divide 100 by your strip's wattage per meter to find the maximum length. A strip rated at 8W/m, for example, could run up to 12.5 meters (100W / 8W per meter). Always check your strip's rated power per meter before sizing.

Can I mount the HLG-100H-20AB in a sheltered outdoor location?

Yes. Its IP65 rating protects against dust and low-pressure water jets, making it suitable for covered outdoor areas such as porches, carports, and awnings. Avoid locations where it could be submerged or directly exposed to heavy rain — use an IP67 model like the HLG-100H-20B for those conditions.
