Frequently Asked Questions

Can I use the HLG-320H-15AB to power dimmable 15V LED retail display lighting?

Yes. The HLG-320H-15AB provides 285W at 15V with both a built-in potentiometer for output adjustment and a dimming input that accepts 1-10V, PWM, or resistance signals. This combination is ideal for retail environments where you need both precise output tuning and dynamic brightness control throughout the day.

Is the HLG-320H-15AB a good choice for 15V LED task lighting in an office with a lighting control system?

Yes. The dimming input on the HLG-320H-15AB integrates with building automation and DALI-to-analog converters, allowing the lighting system to adjust brightness on schedule or by occupancy sensor. The potentiometer lets you set the maximum output level to match the fixture requirements.

Can the HLG-320H-15AB be used for 15V LED accent lighting in a hospitality setting?

Yes. At 285W and 15V, it has enough capacity for extensive accent lighting runs. The dimming input allows integration with scene controllers for different ambiance settings, while the adjustable output ensures the driver matches the LED modules' ideal operating point.

How much 15V LED strip can the HLG-320H-15AB power?

The HLG-320H-15AB provides up to 285W at 15V. Divide 285W by your strip's rated wattage per meter to estimate the maximum run length. For example, a 15V strip rated at 12W/m would allow 285 / 12 = approximately 23.7 meters. Always check your strip's rated power per meter and stay within 285W total.

Can the HLG-320H-15AB be mounted in a semi-exposed outdoor location like under an awning?

Yes. Its IP65 water-resistant rating protects against dust and low-pressure water jets, making it appropriate for covered or semi-sheltered outdoor installations such as awnings, canopies, and building soffits. It should not be placed where submersion or heavy pooling water may occur — use an IP67 model like the HLG-320H-15B for those conditions.
