Frequently Asked Questions
Can I use the HLG-40H-48 to power 48V LED panel lights?
Yes. The HLG-40H-48 outputs 48V at up to 0.84A (40W) in constant-current mode, which matches 48V LED panels commonly found in commercial ceiling grids and architectural fixtures. The CC voltage range of 28-48V also supports panels with varying forward voltages.
Is the HLG-40H-48 suitable for 48V LED strip lighting outdoors?
Yes. Its IP67 waterproof rating protects against rain, sprinklers, and temporary submersion, so it can be mounted in exposed outdoor locations. The 40W capacity at 48V is appropriate for short runs of 48V LED strip used in architectural or landscape accent lighting.
Can the HLG-40H-48 drive 48V LED modules in a compact light box?
Yes, provided the total module load does not exceed 40W. The 48V output at 0.84A matches standard 48V LED module strings used in small light boxes and cabinet signs. The wide 90-305VAC input accommodates varying mains voltages in commercial settings worldwide.
How many meters of 48V LED strip can the HLG-40H-48 handle?
That depends on the strip's power draw per meter. The HLG-40H-48 delivers up to 40W at 48V. For example, a strip consuming 8W/m could run up to 5 meters (40W / 8W per meter = 5m). Always verify your strip's rated power per meter and keep the total load at or below 40W.
Can the HLG-40H-48 be mounted outdoors without a secondary enclosure?
Yes. Its IP67 rating means the aluminium casing is fully sealed against dust and protected against temporary water immersion up to 1 meter. It can be mounted directly outdoors in rain, snow, or high-humidity conditions without additional weatherproofing.
