Frequently Asked Questions
Can I use the HLG-320H-20B with a dimmer to control large outdoor 20V LED strip runs?
Yes. The HLG-320H-20B supports 1-10V and PWM dimming and delivers 300W at 20V with an IP67 waterproof rating. This makes it well suited for outdoor LED strip installations where you need both high power and smooth brightness control in rain-exposed locations.
Is the HLG-320H-20B a good driver for 20V LED flood or area lighting?
Yes. With 300W at 20V and 15A of output current, the HLG-320H-20B can drive high-power 20V LED flood lights or area lighting fixtures. Its IP67 rating allows direct outdoor mounting without an additional enclosure.
Can the HLG-320H-20B power 20V LED modules in an outdoor commercial sign?
Yes. At 300W and 20V it handles substantial signage loads, and the dimming input lets you reduce brightness at night to save energy or meet local ordinances. The IP67 waterproof housing withstands rain, snow, and hose-down cleaning.
How many meters of 20V LED strip can the HLG-320H-20B drive?
The HLG-320H-20B delivers up to 300W. Divide 300 by your strip's wattage per meter to find the maximum length. A strip rated at 10W/m, for example, could run up to 30 meters (300W / 10W per meter = 30m). Always check your strip's rated power per meter before sizing.
Can the HLG-320H-20B be mounted outdoors in direct rain or snow?
Yes. Its IP67 waterproof rating means it is protected against temporary submersion up to 1 meter, so direct rain, snow, and hose-down cleaning are not a concern. It can be mounted without any additional weatherproof enclosure.
What are the differences between the HLG-320H-20, 20A, 20AB, and 20B models?
All four share the same 300W / 20V / 15A core specs. The base HLG-320H-20 has no output adjustment or dimming and is IP67. The -20A adds output voltage/current adjustment via potentiometer and is IP65. The -20AB adds both adjustment and 1-10V/PWM dimming (IP65). The -20B provides dimming input only and retains IP67.
