Frequently Asked Questions
Can I use the HLG-80H-20B for outdoor 20V LED strip lighting with dimming control?
Yes. The HLG-80H-20B outputs 20V at up to 4A (80W) with an IP67 waterproof rating and a 1-10V/PWM dimming input. It can be installed in fully exposed outdoor locations and dimmed via an external controller for daylight-responsive or scheduled brightness adjustments.
Is the HLG-80H-20B a good choice for dimmable 20V LED signage exposed to weather?
Yes. At 80W and 20V with IP67 waterproof protection, it can drive 20V sign modules in fully exposed outdoor locations. The B-type dimming input lets you pair with a controller for day/night brightness scheduling without needing a separate weatherproof enclosure for the driver.
Can the HLG-80H-20B drive 20V LED lighting in a landscape or garden installation?
Yes. The IP67 rating means it can handle direct rain, sprinkler splash, and temporary submersion. With 80W at 20V and an operating range of -40°C to +80°C, it is well suited for buried-enclosure or pole-mounted landscape lighting applications using 20V LED fixtures.
How many meters of 20V LED strip can the HLG-80H-20B drive?
It depends on the strip's rated wattage per meter. The HLG-80H-20B provides up to 80W at 20V. If your strip uses 10W/m, you could run up to 8 meters (80W / 10W per meter = 8m). Always check your strip's rated power per meter and keep the total load at or below 80W.
Can the HLG-80H-20B withstand installation in a flood-prone or below-grade enclosure?
Its IP67 rating protects against temporary submersion in water up to 1 meter depth, so it can handle brief flooding in below-grade vaults or ground-level enclosures. For permanently submerged conditions, additional protection or a higher-rated enclosure would be needed.
