Frequently Asked Questions
Can I use the HLG-480H-54A to power adjustable 54V LED lighting in a commercial space?
Yes. The HLG-480H-54A delivers 480W at 54V and includes a built-in potentiometer for output voltage and current adjustment. This lets you trim the output to precisely match your 54V LED fixtures, which is useful in commercial retrofit projects where exact voltage tuning is needed.
Is the HLG-480H-54A suitable for 54V LED grow light systems?
Yes. Its 480W output at 54V with adjustable voltage and current can drive high-power 54V LED grow panels. The built-in potentiometer lets you adjust light intensity without an external dimmer, and the aluminium casing dissipates heat effectively in grow tent or greenhouse environments.
Can the HLG-480H-54A power long runs of 54V LED strip for architectural lighting?
Yes. At 480W and 8.9A, this driver handles substantial 54V LED strip installations. The higher 54V rail reduces voltage drop over distance, and the adjustable output lets you fine-tune to the optimal voltage for your specific strip, which helps maintain even brightness along the run.
How many meters of 54V LED strip can the HLG-480H-54A handle?
That depends on the strip's rated power per meter. The HLG-480H-54A supplies up to 480W at 54V. For a strip rated at 16W/m, you could run up to 30 meters (480W / 16W per meter = 30m). Always check your strip's rated power per meter and keep total load at or below 480W.
Can the HLG-480H-54A be used in a semi-exposed outdoor installation?
Yes. Its IP65 water-resistant rating protects against dust and low-pressure water jets, making it suitable for under-eave, canopy, or covered patio mounting. For fully exposed or submersible installations, consider the IP67-rated HLG-480H-54 or HLG-480H-54B.
What is the difference between the HLG-480H-54A and HLG-480H-54AB?
Both are 480W / 54V / 8.9A and IP65 rated. The HLG-480H-54A has an output adjustment potentiometer but no dimming input. The HLG-480H-54AB adds a 1-10V/PWM dimming input in addition to the adjustment potentiometer, giving you external brightness control from a wall dimmer or automation system.
