Frequently Asked Questions
Can I use the HLG-120H-24AB with a building automation system to dim 24V LED strips?
Yes. The HLG-120H-24AB accepts 1-10V and PWM dimming signals, which most building automation and lighting control systems can provide. It outputs 24V at up to 5A (120W) and lets you dim your 24V LED strips from a central controller or smart panel.
Is the HLG-120H-24AB a good choice for retail display lighting that needs brightness adjustment?
Yes. The combination of adjustable output via potentiometer and external dimming input (1-10V/PWM) makes it flexible for retail display cases, accent lighting, and shelf lighting where brightness needs to change for different displays or times of day. It delivers up to 120W at 24V.
Can the HLG-120H-24AB drive dimmable 24V LED signage?
Yes. At 120W and 24V output with dimming capability, it can power 24V LED sign modules while allowing brightness reduction for nighttime or energy-saving schedules. The built-in potentiometer also lets you fine-tune the maximum output to match your sign's requirements precisely.
How many meters of 24V LED strip can the HLG-120H-24AB drive at full brightness?
The HLG-120H-24AB provides up to 120W at 24V. If your strip draws 20W/m, you could run up to 6 meters (120W / 20W per meter = 6m). If the strip draws 9.6W/m, you could run up to 12.5 meters. Always check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-24AB be installed in a damp commercial kitchen or food-service area?
Yes. Its IP65 water-resistant rating protects against low-pressure water jets and dust, making it suitable for covered wet areas, commercial kitchens, and food-prep zones. For areas subject to direct hosing or standing water, the IP67-rated HLG-120H-24B with dimming would be a better match.
