Frequently Asked Questions
Can I use the HLG-40H-15B to power 15V LED strips in a fully exposed outdoor installation?
Yes. The HLG-40H-15B is rated IP67 waterproof and delivers 15V at up to 2.67A (40.5W), making it suitable for outdoor 15V LED strip projects exposed to rain, sprinklers, or temporary submersion. Its -40°C to +80°C operating range also handles harsh temperature swings.
Is the HLG-40H-15B a good choice for dimmable 15V LED signage?
Yes. It supports dimming via external signals, which allows scene-based brightness control for signage. At 40.5W and 15V output, it can drive small LED sign modules. The IP67 rating means the driver can be mounted inside outdoor sign enclosures without concern for moisture damage.
Can I use the HLG-40H-15B for a small dimmable 15V landscape lighting setup?
It works well for compact landscape lighting systems that use 15V LED fixtures. The IP67 waterproof rating allows burial in waterproof junction boxes or direct outdoor exposure, and the dimming function lets you adjust brightness for different times of day. Total load must stay at or below 40.5W.
How many meters of 15V LED strip can the HLG-40H-15B drive?
The HLG-40H-15B supplies up to 40.5W at 15V. Divide 40.5W by your strip's rated wattage per meter to find the maximum run length. For example, a strip rated at 5W per meter would allow roughly 8.1 meters (40.5W / 5W per meter = 8.1m). Always check your strip's rated power per meter and stay within the 40.5W limit.
Can the HLG-40H-15B be installed in a location that floods occasionally?
The IP67 rating means the HLG-40H-15B can withstand temporary immersion in water up to 1 meter for 30 minutes. While it handles occasional flooding, it is not designed for permanent submersion. The sealed aluminium casing provides strong protection against dust and moisture ingress in damp environments.
