Frequently Asked Questions
Can I use the HLG-40H-24 to power 24V LED strip lighting outdoors?
Yes. The HLG-40H-24 outputs 24V at up to 1.67A (40W) and carries an IP67 waterproof rating, making it a reliable choice for outdoor 24V LED strip projects exposed to rain, snow, or dust. The aluminium housing and -40°C to +80°C operating range add durability in harsh conditions.
Is the HLG-40H-24 suitable for a small 24V LED under-cabinet lighting setup?
It works well for compact 24V under-cabinet installations where total LED load stays within 40W. The HLG-40H-24 provides a fixed 24V output in constant-current mode, delivering consistent brightness. Its compact 171 x 61.5 x 36.8 mm dimensions allow placement in tight spaces behind cabinetry.
Can the HLG-40H-24 power a short run of 24V LED neon flex for signage?
Yes, provided the neon flex draws 40W or less in total. Many 24V LED neon flex products consume 10-15W per meter, so the HLG-40H-24 could support roughly 2.5 to 4 meters depending on the flex's power rating. Check your specific product's rated power per meter to confirm.
How many meters of 24V LED strip can the HLG-40H-24 support?
That depends on the strip's rated power per meter. The HLG-40H-24 provides 40W at 24V. For example, if your strip draws 14.4W per meter, you could run approximately 2.7 meters (40W / 14.4W per meter = 2.77m). Always check your strip's rated power per meter and keep total load at or below 40W.
Can the HLG-40H-24 be installed in an outdoor location with direct rain exposure?
Yes. The IP67 waterproof rating means the HLG-40H-24 is dust-tight and can handle temporary immersion in water up to 1 meter deep. Direct rain, sprinkler overspray, and seasonal flooding are all within its design tolerance. The sealed aluminium case prevents moisture from reaching the electronics.
What are the differences between the HLG-40H-24 and HLG-40H-24A?
Both deliver 40W at 24V and 1.67A. The base HLG-40H-24 has fixed output and an IP67 waterproof rating. The HLG-40H-24A adds a built-in potentiometer for adjustable output voltage and current but carries a lower IP65 water-resistant rating. Choose the -24A when you need output tuning in a sheltered location, or the base -24 when waterproofing is the priority.
