Frequently Asked Questions
Can I use the HLG-120H-20AB with a 0-10V dimmer to control 20V LED lighting?
Yes. The HLG-120H-20AB supports dimming via 1-10V, PWM, and resistance signals, making it compatible with standard 0-10V dimmers. This lets you smoothly adjust brightness on 20V LED strips or fixtures while the driver handles up to 120W of total load at 6A.
Is the HLG-120H-20AB a good choice for dimmable 20V LED retail or gallery lighting?
It is well suited for retail or gallery lighting where both output tuning and dimming are needed. The built-in potentiometer lets you set the baseline voltage and current, while the dimming input allows scene-based brightness control. At 120W and 20V output, it drives medium-scale display lighting installations.
Can I power a 20V dimmable LED light panel with the HLG-120H-20AB?
Yes, as long as the panel draws 120W or less. The HLG-120H-20AB delivers 20V at up to 6A in constant-current mode, and its dimming interface lets you adjust brightness for different times of day or ambient conditions. The adjustable output also lets you dial in the optimal operating point within the 10-20V range.
Can I use the HLG-120H-20AB for dimmable 20V LED under-counter or task lighting?
Yes. The HLG-120H-20AB provides 120W at 20V with both adjustable output and dimming, making it ideal for task lighting where brightness needs to change throughout the day. The adjustable output lets you optimize the drive current for your specific 20V LED strips or modules.
How many meters of 20V LED strip can the HLG-120H-20AB drive?
The HLG-120H-20AB provides 120W at 20V. Divide 120W by your strip's wattage per meter. For example, a 20V strip rated at 15W/m would allow up to 8 meters (120W / 15W per meter = 8m). Check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-20AB be mounted outdoors in an exposed location?
The HLG-120H-20AB carries an IP65 water-resistant rating, which protects against dust and low-pressure water sprays. It is suitable for sheltered outdoor spots such as covered signage enclosures or under eaves, but not for locations subject to submersion or heavy water jets. For fully exposed outdoor use with dimming, consider the IP67-rated HLG-120H-20B.
