Frequently Asked Questions
Can I use the HLG-40H-30 for 30V LED strip lighting in an outdoor setting?
Yes. The HLG-40H-30 provides 30V at up to 1.34A (40W) with an IP67 waterproof rating. It can be mounted outdoors in locations exposed to rain or moisture without additional weatherproofing, making it suitable for 30V LED strip runs on building exteriors or garden structures.
Is the HLG-40H-30 a good choice for powering 30V LED modules in a light box?
Yes, provided the total module load does not exceed 40W. The HLG-40H-30 delivers 30V in constant-current mode with a CC range of 18-30V, which accommodates slight voltage variations across LED module strings. The wide 90-305VAC input handles virtually any mains supply.
Can the HLG-40H-30 power 30V LED fixtures in a commercial cooler or freezer?
Yes. Its operating temperature range of -40°C to +80°C covers cold-storage environments, and IP67 waterproofing protects against moisture from condensation or washdowns. At 40W it can handle small to medium 30V LED fixture loads typically found in cooler display cases.
How many meters of 30V LED strip can the HLG-40H-30 support?
Divide 40W by your strip's wattage per meter. For example, a 30V strip consuming 8W/m could run up to 5 meters (40W / 8W per meter = 5m). A strip at 13W/m would allow roughly 3 meters. Check your strip's rated power per meter and keep total consumption at or below 40W.
Can the HLG-40H-30 be installed fully exposed to weather without an enclosure?
Yes. The IP67 waterproof rating means the unit can withstand temporary submersion up to 1 meter and is fully protected against dust. Combined with its aluminium casing and -40°C to +80°C operating range, it can be mounted directly outdoors without any additional protective enclosure.
What are the differences between the HLG-40H-30, 30A, 30AB, and 30B models?
All four deliver 40W at 30V / 1.34A with a CC range of 18-30V. The base HLG-40H-30 has fixed output and IP67 waterproofing. The -30A adds output voltage/current adjustment via potentiometer (IP65). The -30AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -30B offers dimming input only and retains IP67.
