Frequently Asked Questions
Can I use the HLG-120H-30AB with a lighting control system to dim 30V LED fixtures?
Yes. The HLG-120H-30AB accepts 1-10V and PWM dimming signals from external controllers, building automation systems, or smart lighting panels. It delivers up to 120W at 30V, and the dimming capability lets you schedule brightness levels or create dynamic lighting scenes.
Is the HLG-120H-30AB suitable for adjustable and dimmable 30V LED display lighting?
Yes. It combines a built-in potentiometer for output voltage/current trimming with an external dimming input, making it especially flexible for retail displays, museum cases, or gallery lighting where both initial calibration and ongoing brightness control are needed. It delivers up to 120W at 30V.
Can the HLG-120H-30AB drive dimmable 30V LED signage for nighttime dimming schedules?
Yes. At 120W and 30V with dimming input, it can power 30V LED sign modules while allowing brightness reduction for nighttime energy savings. The adjustable output also lets you calibrate the maximum brightness to match the sign manufacturer's recommendations precisely.
How many meters of 30V LED strip can the HLG-120H-30AB power at full output?
The HLG-120H-30AB delivers up to 120W at 30V. For a strip rated at 10W/m, you could run up to 12 meters (120W / 10W per meter = 12m). For a 24W/m strip, the limit is 5 meters. Always check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-30AB be used in a covered but humid environment like a greenhouse or pool house?
Yes. Its IP65 water-resistant rating handles humidity, condensation, and splashing water typical of greenhouses, pool houses, and covered wash areas. For installations with direct rain or potential submersion, the IP67-rated HLG-120H-30B with dimming would be a better option.
