Frequently Asked Questions
Can I use the HLG-40H-36AB to power 36V LED strip lighting with dimming control?
Yes. The HLG-40H-36AB delivers 40W at 36V with both adjustable output and 1-10V/PWM dimming input, so you can fine-tune brightness from a wall dimmer or automation system. Its IP65 water-resistant rating suits covered outdoor or damp indoor locations.
Is the HLG-40H-36AB a good fit for small 36V LED signage projects?
Yes. At 40W and 36V output, it can drive small channel letters or light-box signs that run on 36V LED modules. The built-in dimming input lets you adjust sign brightness for day/night schedules, and the adjustable output trims voltage to match your exact module string.
Can the HLG-40H-36AB power 36V LED linear fixtures in a display case?
Yes, provided the total fixture load stays within 40W. The constant-current mode with a CC voltage range of 21-36V accommodates fixtures that may draw slightly less than full voltage. The adjustable output and dimming input give precise brightness control for retail display lighting.
How many meters of 36V LED strip can the HLG-40H-36AB handle?
That depends on your strip's rated power per meter. The HLG-40H-36AB supplies up to 40W at 36V. For example, if your strip draws 8W/m, you could run up to 5 meters (40W / 8W per meter = 5m). Always check your strip's rated power per meter and keep the total load at or below 40W.
Can the HLG-40H-36AB be installed in a sheltered outdoor location?
Yes. Its IP65 rating protects against dust ingress and low-pressure water jets, making it suitable for covered patios, soffits, or ventilated outdoor enclosures. For fully exposed rain or submersion scenarios, consider the IP67-rated HLG-40H-36B instead.
What are the differences between the HLG-40H-36, 36A, 36AB, and 36B models?
All four share the same 40W / 36V / 1.12A core specs. The base HLG-40H-36 has no output adjustment or dimming and is IP67 waterproof. The -36A adds a built-in potentiometer for voltage/current adjustment (IP65). The -36AB adds both adjustment and 1-10V/PWM dimming (IP65). The -36B adds dimming input only and retains IP67.
