Frequently Asked Questions
Can I use the HLG-100H-20B with a PWM dimmer to control outdoor 20V LED strips?
Yes. The HLG-100H-20B accepts PWM and 1-10V dimming signals and carries an IP67 waterproof rating, so it can be dimmed via an external controller even in fully exposed outdoor installations. It delivers up to 100W at 20V.
Is the HLG-100H-20B suitable for dimmable 20V LED sign lighting exposed to weather?
Yes. Its IP67 waterproof enclosure handles rain, snow, and temporary submersion, while its dimming input lets you reduce sign brightness at night to save energy or meet local lighting ordinances. The 100W capacity at 20V covers most medium-sized sign arrays.
Can the HLG-100H-20B power dimmable 20V landscape lighting?
Yes. The combination of 100W at 20V output, IP67 waterproofing, and dimming capability (1-10V/PWM) makes it well suited for in-ground, path, or garden LED fixtures that operate on 20V. Its -40°C to +80°C operating temperature range handles seasonal extremes.
How much 20V LED strip can the HLG-100H-20B support?
Up to 100W total. Divide 100 by the strip's rated wattage per meter. For a 12W/m strip, the maximum is about 8.3 meters (100W / 12W per meter = 8.3m). Check your strip's rated power per meter and stay within the 100W limit.
Can the HLG-100H-20B survive being buried in a ground-level vault or below-grade enclosure?
Its IP67 rating means it can withstand temporary immersion in water up to 1 meter deep for 30 minutes. This makes it viable for below-grade vaults that may occasionally flood, but it is not designed for continuous submersion. Ensure proper drainage in the enclosure.
What is the difference between the HLG-100H-20B and the HLG-100H-20AB?
Both are 100W / 20V / 4.8A and both accept dimming signals. The key differences: the -20B has IP67 waterproof protection but no output adjustment potentiometer, while the -20AB has both adjustment and dimming but is rated IP65 (water-resistant, not waterproof). Choose the -20B for full outdoor exposure or the -20AB when you need manual output trimming.
