Frequently Asked Questions
Can I use the HLG-40H-36A to fine-tune output for a 36V LED art or display installation?
Yes. The HLG-40H-36A includes a built-in potentiometer that lets you adjust the output voltage and current. This is useful for art installations or display cases where the 36V LEDs may need a slightly lower drive level to achieve the desired color temperature or brightness without adding a separate controller.
Is the HLG-40H-36A suitable for powering 36V LED strips in retail shelf lighting?
Yes. At 40W and 36V it can drive typical retail shelf or cabinet LED strip runs. The adjustable output lets you match the driver precisely to the strip's optimal voltage, reducing potential over-driving and extending LED lifespan. The compact 171 x 61.5 x 36.8 mm form factor fits easily above ceiling tiles or behind display shelves.
Can the HLG-40H-36A power 36V LED modules in an indoor light box?
Yes, as long as total module power stays within 40W. The constant-current CC range of 21-36V accommodates LED module strings that may operate slightly below the full 36V. The potentiometer adjustment is helpful for balancing brightness uniformity across the light box surface.
How many meters of 36V LED strip can the HLG-40H-36A handle?
Divide 40W by your strip's rated wattage per meter. For a 36V strip drawing 8W/m, you can run 5 meters (40W / 8W per meter = 5m). For a higher-density strip at 14W/m, about 2.8 meters. Always verify your strip's rated power per meter and keep total consumption within 40W.
Is the HLG-40H-36A water-resistant enough for a damp warehouse or garage?
Yes. Its IP65 rating protects against dust ingress and low-pressure water jets, which is more than adequate for damp warehouses, garages, or covered loading docks. For locations with direct rain exposure or potential standing water, consider the IP67-rated HLG-40H-36 base model.
