Frequently Asked Questions
Can I use the HLG-80H-20A for 20V LED strip lighting in a covered outdoor area?
Yes. The HLG-80H-20A delivers 20V at up to 4A (80W) with an IP65 water-resistant rating, making it suitable for covered patios, soffits, and canopies where splashing water and dust are present. For fully exposed rain locations, the IP67-rated HLG-80H-20 or HLG-80H-20B would be a better fit.
How does the adjustable output on the HLG-80H-20A help with LED brightness control?
The built-in potentiometer lets you trim the output voltage and current without needing an external dimmer. This is useful when your 20V LED load draws slightly less than the full rated output and you want to fine-tune brightness or reduce power consumption. The CC voltage range is 12-20V.
Is the HLG-80H-20A a good driver for 20V LED signage modules?
Yes. With 80W at 20V, it can power 20V channel letters or light-box modules. The adjustable output potentiometer lets you match the driver precisely to the module string voltage, reducing waste heat and improving efficiency. Its wide 90-305VAC input handles most commercial mains supplies.
How many meters of 20V LED strip can I run from the HLG-80H-20A?
That depends on the strip's wattage per meter. The HLG-80H-20A supplies up to 80W at 20V. For a strip rated at 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.
Is the HLG-80H-20A suitable for damp locations like a bathroom soffit or covered car wash?
Its IP65 rating protects against low-pressure water jets and dust ingress, which covers damp environments like bathroom soffits or sheltered car-wash areas. For locations with direct water immersion risk, step up to the IP67-rated HLG-80H-20 or 20B.
What are the differences between the HLG-80H-20, 20A, 20AB, and 20B models?
All four share the same 80W / 20V / 4A core specs and 195.6 x 61.5 x 38.8 mm dimensions. The base HLG-80H-20 has no output adjustment and is IP67 waterproof. The -20A adds output voltage/current adjustment via built-in potentiometer and is IP65. The -20AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -20B adds dimming input only and retains IP67.
