Frequently Asked Questions
Can I use the HLG-480H-42B for outdoor 42V LED strip lighting with dimming control?
Yes. The HLG-480H-42B provides 480W at 42V with a dimming signal input (1-10V, PWM, or resistance) and an IP67 waterproof rating. This combination makes it well suited for outdoor LED strip installations where you need weather resistance and external brightness control.
Is the HLG-480H-42B appropriate for dimmable 42V LED landscape lighting?
Yes. At 480W and 42V, it can drive multiple landscape fixtures or bollard lights operating on 42V. The dimming input allows integration with landscape lighting controllers for timed or scene-based dimming. Its IP67 rating and -40°C to +90°C operating range handle ground-level outdoor exposure year-round.
Can the HLG-480H-42B power 42V LED tunnel or underpass lighting?
Yes. With 480W output, wide 90-305VAC input, and IP67 waterproof construction, it is suitable for tunnel or underpass environments that experience moisture, dust, and temperature extremes. The dimming capability allows brightness adjustment to match traffic conditions or time-of-day requirements.
How many meters of 42V LED strip can the HLG-480H-42B drive?
Divide 480W by the strip's power consumption per meter. For example, a 42V strip rated at 20W/m would allow up to 24 meters (480W / 20W per meter = 24m). Check your strip's rated power per meter and keep total load at or below 480W for reliable operation.
Can the HLG-480H-42B withstand submersion or heavy rain?
Yes. The IP67 rating means the enclosure is protected against temporary submersion in water up to 1 meter for 30 minutes and fully sealed against dust. It can be mounted in locations subject to direct rain, flooding, or washdown without additional weatherproofing.
