Frequently Asked Questions
Can I use the HLG-185H-24AB for dimmable 24V LED lighting in a restaurant or hospitality setting?
Yes. The HLG-185H-24AB delivers 185W at 24V with built-in 1-10V/PWM dimming input, making it well-suited for hospitality environments where lighting scenes change throughout the day. The adjustable output also lets you trim voltage and current to match the exact LED load.
Can the HLG-185H-24AB power dimmable 24V LED strip in a covered patio or pergola?
Yes. The IP65 water-resistant rating handles splashing water and dust in sheltered outdoor areas like covered patios, pergolas, or gazebos. The built-in dimming input lets you pair with a 1-10V or PWM controller to adjust brightness for different times of day without additional dimmable drivers.
Is the HLG-185H-24AB a good choice for adjustable-brightness 24V LED signage indoors?
Yes. With 185W at 24V and both output adjustment and dimming capability, it can power 24V LED signs where brightness needs to change — for example, retail displays that dim at night or trade show lighting that adapts to ambient light. The adjustable output trims the base voltage to match the sign modules precisely.
How many meters of 24V LED strip can the HLG-185H-24AB drive?
Divide 185W by your strip's power per meter. A strip rated at 19.2W/m allows about 9.6 meters (185W / 19.2W per meter ≈ 9.6m), while a 9.6W/m strip allows about 19.2 meters. Always check your strip's rated power per meter and keep total load at or below 185W.
Can the HLG-185H-24AB be used in a covered outdoor area exposed to humidity and dust?
Yes. The IP65 rating provides full dust protection and resistance to low-pressure water jets, which covers covered outdoor environments with humidity, condensation, or occasional splashing. For fully rain-exposed or submersible installations, the IP67-rated HLG-185H-24B would be a better fit.
What dimming options does the HLG-185H-24AB support compared to the other 24V variants?
The HLG-185H-24AB supports both output adjustment via built-in potentiometer and external dimming via 1-10V analog or PWM signal. The -24A offers adjustment only (no dimming input), the -24B offers dimming input only (no potentiometer adjustment), and the base -24 has fixed output with no adjustment or dimming. All four share the same 185W / 24V / 7.8A output.
