Frequently Asked Questions

Can I use the HLG-40H-24A for adjustable 24V LED display case lighting?

Yes. The HLG-40H-24A delivers 24V at up to 1.67A (40W) and includes a built-in potentiometer to adjust output voltage and current. This is practical for display cases where you want to fine-tune brightness to match the merchandise without needing an external dimmer.

Is the HLG-40H-24A suitable for 24V LED strip cove lighting with adjustable output?

It is well suited for indoor cove lighting where you need to dial in the exact operating point. The adjustable output covers the 14-24V constant-current range, letting you optimize brightness and efficiency for your specific LED strip. Total load must remain at or below 40W.

Can I power 24V LED modules in a small sign with the HLG-40H-24A?

Yes, provided total module power stays under 40W. The HLG-40H-24A's adjustable output lets you match voltage precisely to your LED modules within the 14-24V range. The IP65 rating is adequate when the driver is housed inside a weatherproof sign cabinet or indoor enclosure.

How many meters of 24V LED strip can the HLG-40H-24A drive?

The HLG-40H-24A supplies up to 40W at 24V. Divide 40W by your strip's rated wattage per meter. For example, a strip rated at 10W per meter would allow up to 4 meters (40W / 10W per meter = 4m). Always check your strip's rated power per meter and keep total load within the 40W limit.

Can the HLG-40H-24A be installed in a bathroom or humid indoor area?

The HLG-40H-24A is rated IP65, which provides protection against dust and low-pressure water jets. It can handle humid indoor environments like bathrooms when mounted away from direct water spray. For locations with higher water exposure, consider the IP67-rated HLG-40H-24 base model.
