Frequently Asked Questions

Can I use the HLG-320H-36A for 36V LED strip lighting where I need to fine-tune brightness?

Yes. The HLG-320H-36A features a built-in potentiometer that lets you adjust the output voltage and current within the 18-36V constant-current range. This is useful for optimizing brightness and efficiency when the LED strip does not need exactly 36V or the full 8.9A.

Is the HLG-320H-36A suitable for powering 36V LED architectural or landscape lighting?

It works well for architectural and landscape lighting where the load needs to be tuned. The adjustable output accommodates slight voltage variations across different LED fixtures, and 320W is sufficient for substantial lighting runs. Mount it in a sheltered location since it is rated IP65 rather than IP67.

Can I use the HLG-320H-36A for a 36V LED grow light setup?

Yes, provided total power draw is within 320W. The adjustable output lets you set the precise current for your grow light panels. Its wide 90-305VAC input handles different electrical supplies, and the 18-36V constant-current range accommodates various 36V LED grow light configurations.

How many meters of 36V LED strip can the HLG-320H-36A handle?

The HLG-320H-36A delivers up to 320W at 36V. Divide 320W by your strip's rated wattage per meter. For example, a strip at 18W/m would support roughly 17.7 meters (320W / 18W per meter). Always verify your strip's rated power per meter and stay within the 320W limit.

Is the HLG-320H-36A suitable for an exposed outdoor installation?

The HLG-320H-36A carries an IP65 water-resistant rating, which protects against dust and low-pressure water jets. It is suitable for sheltered outdoor locations such as covered canopies or weatherproof enclosures. For fully exposed outdoor installations, the IP67-rated HLG-320H-36 or HLG-320H-36B would be more appropriate.

What does the 'A' suffix mean on the HLG-320H-36A versus the base HLG-320H-36?

The 'A' suffix indicates the model includes a built-in potentiometer for adjusting output voltage and current. The base HLG-320H-36 has fixed output. The -36A also carries an IP65 water-resistant rating instead of the base model's IP67 waterproof rating. Both share the same 320W, 36V, 8.9A output at default settings.
