Frequently Asked Questions

Can I use the HLG-320H-12B to power 12V LED strips for an outdoor architectural facade?

Yes. The HLG-320H-12B delivers 264W at 12V and carries an IP67 waterproof rating, meaning it can withstand dust and temporary water immersion. This makes it an excellent choice for fully exposed outdoor facade lighting where the driver may encounter rain, snow, or washdown conditions.

Is the HLG-320H-12B a good driver for 12V LED landscape lighting?

Yes. With 264W at 12V and IP67 waterproof protection, the HLG-320H-12B is well suited for landscape and garden LED systems. It can be mounted in ground-level junction boxes or outdoor enclosures exposed to irrigation spray and seasonal weather.

Can the HLG-320H-12B drive 12V LED lighting in a car wash or wet industrial area?

Yes. The IP67 waterproof enclosure is rated for temporary immersion and full dust protection, making it suitable for high-moisture environments like car washes, food processing areas, or wash-down zones. The 264W at 12V output handles substantial LED loads in these settings.

How many meters of 12V LED strip can I run from the HLG-320H-12B?

The HLG-320H-12B provides up to 264W at 12V. Divide 264W by your strip's rated wattage per meter to find the maximum length. For instance, a strip rated at 10W/m would allow up to 264 / 10 = 26.4 meters. Always check your strip's rated power per meter and stay within the 264W total.

Can the HLG-320H-12B handle extreme cold or heat in outdoor installations?

Yes. The HLG-320H-12B has an operating temperature range of -40°C to +90°C, covering harsh winter cold through intense summer heat. Combined with its IP67 waterproof rating, it is designed for year-round outdoor deployment in virtually any climate.

Can the HLG-320H-12B be dimmed, and how does dimming work on this model?

Yes. The -B suffix indicates a built-in dimming function that accepts 1-10V, PWM, or resistance signals. This allows integration with external dimmers or automation controllers. Unlike the -AB model, the -12B does not include a potentiometer for manual voltage/current adjustment.
