Frequently Asked Questions
Can I use the HLG-40H-42 to power 42V LED panel lights?
Yes. The HLG-40H-42 delivers 40W at 42V in constant-current mode, which suits 42V LED panels commonly used in commercial and architectural lighting. Its CC voltage range of 25-42V also accommodates panels with slightly lower forward-voltage requirements during startup.
Is the HLG-40H-42 a good choice for outdoor 42V LED landscape lighting?
Yes. With an IP67 waterproof rating it can handle direct rain, sprinkler exposure, and ground-level moisture. The 40W output at 42V is well-suited for small landscape accent fixtures or path lights that run on a 42V bus.
Can the HLG-40H-42 drive 42V LED modules in a small light box or sign?
Yes, provided the total load does not exceed 40W. At 42V and 0.96A, it matches standard 42V LED module strings. The wide 90-305VAC input range accommodates most mains voltages worldwide, which is useful for commercial signage installations.
How many meters of 42V LED strip can the HLG-40H-42 support?
That depends on the strip's power consumption per meter. The HLG-40H-42 supplies up to 40W at 42V. For a strip rated at 8W/m you could run up to 5 meters (40W / 8W per meter = 5m). Always verify your strip's rated power per meter and keep total draw at or below 40W.
Can the HLG-40H-42 be left exposed to rain without an additional enclosure?
Yes. Its IP67 rating means the unit is sealed against dust and protected against temporary submersion in water up to 1 meter. It can be mounted outdoors without a secondary enclosure, even in heavy rain or sprinkler zones.
