Frequently Asked Questions

Can I use the HLG-150H-54A to fine-tune output for 54V LED high-bay fixtures?

Yes. The HLG-150H-54A has a built-in potentiometer that lets you adjust output voltage and current. This is useful when your 54V high-bay fixtures need a slightly lower drive level or when matching the driver precisely to the LED module's optimal forward voltage within the 27-54V CC range.

Is the HLG-150H-54A a good choice for 54V LED floodlights in a covered parking structure?

Yes. At 150W and 54V with IP65 water-resistant protection, the HLG-150H-54A handles dust and low-pressure water jets typical of covered parking garages or canopied areas. The adjustable output lets you dial in the exact brightness level for the floodlights.

Can the HLG-150H-54A power series-connected 54V LED COB arrays?

Yes. The HLG-150H-54A provides up to 2.8A at 54V in constant-current mode, which is ideal for series-connected COB LED arrays. The built-in potentiometer allows you to trim the current to match the COB manufacturer's recommended drive level.

How many 54V LED modules can I connect to the HLG-150H-54A?

The total combined wattage must not exceed 150W. For example, if each module draws 30W at 54V, you could parallel up to five modules (5 × 30W = 150W). Always check each module's rated power consumption and keep the total at or below the driver's 150W capacity.

Can the HLG-150H-54A be used in a damp equipment room or semi-enclosed outdoor cabinet?

Yes. IP65 protects against dust ingress and low-pressure water jets from any direction, which is more than adequate for damp equipment rooms, ventilated outdoor cabinets, or covered canopy installations. For direct rain or standing-water exposure, consider the IP67-rated HLG-150H-54 instead.
