Frequently Asked Questions

Can I use the HLG-240H-20 to power 20V LED strips for a long outdoor run?

Yes. The HLG-240H-20 delivers 20V at up to 12A (240W) with an IP67 waterproof rating, making it suitable for long outdoor LED strip runs. The higher 20V output helps reduce voltage drop over distance compared to 12V systems, which is an advantage for runs exceeding 10 meters.

Is the HLG-240H-20 a good choice for powering 20V LED modules in commercial signage?

Yes. At 240W and 20V output, it can drive a substantial array of 20V LED channel letters, light boxes, or cabinet sign modules. The wide 90-305VAC input accommodates varying commercial mains supplies, and the IP67 waterproof aluminium casing is well suited for outdoor sign enclosures.

Can the HLG-240H-20 drive 20V LED luminaires for warehouse or industrial lighting?

Yes. With 240W of output power and constant-current operation across a CC voltage range of 10-20V, the HLG-240H-20 can reliably drive 20V LED high bays or industrial luminaires. Its -40°C to +90°C operating range handles the temperature extremes found in warehouses and factories.

How many meters of 20V LED strip can the HLG-240H-20 handle?

Divide 240W by your strip's wattage per meter. For example, a strip rated at 16W/m would allow 15 meters (240W / 16W per meter = 15m). Always check your strip's rated power per meter and keep total load at or below 240W for reliable operation.

Can the HLG-240H-20 be mounted outdoors without an additional enclosure?

Yes. Its IP67 waterproof rating protects against complete dust ingress and temporary submersion up to 1 meter, so no additional enclosure is needed even in fully exposed locations. The aluminium casing handles -40°C to +90°C operating temperatures across all seasons.
