Frequently Asked Questions
Can I use the HLG-80H-42 to power 42V LED modules for outdoor signage?
Yes. The HLG-80H-42 outputs 42V at up to 1.95A (80W) with an IP67 waterproof rating, making it suitable for outdoor channel letters, cabinet signs, and light boxes that use 42V LED modules. Its wide 90-305VAC input works with most commercial mains voltages worldwide.
Is the HLG-80H-42 suitable for powering 42V LED grow lights?
Yes, provided the grow light operates at 42V and draws no more than 80W. The HLG-80H-42 runs in constant-current mode with a CC voltage range of 25-42V, which suits many horticultural LED boards. Its IP67 rating also protects against the high humidity typical in grow rooms.
Can I run 42V LED panel lights from the HLG-80H-42 in a warehouse?
Yes. At 80W and 42V output, the HLG-80H-42 can drive 42V panel lights as long as their combined load stays within 80W. The IP67 waterproof and dustproof construction handles the dust, moisture, and temperature swings common in warehouse environments.
How many meters of 42V LED strip can the HLG-80H-42 support?
Divide 80W by your strip's rated power per meter. For example, if your 42V strip draws 12W/m, you can run about 6.6 meters (80W / 12W per meter = 6.67m). Always check your strip's rated power per meter and keep total load at or below 80W.
Can the HLG-80H-42 be mounted outdoors in freezing winter conditions?
Yes. The operating temperature range is -40°C to +80°C, so it handles extreme cold without issue. Combined with IP67 waterproof protection and an aluminium casing, it is built for year-round outdoor exposure including snow and ice conditions.
