Frequently Asked Questions
Can I use the HLG-480H-C2800B for large LED grow light arrays?
Yes. The HLG-480H-C2800B provides 479W at 2800mA constant current with a CC voltage range of 85-171V, making it well-matched to high-wattage LED grow light panels. Its IP65 rating handles the humidity typically found in indoor growing environments.
Is the HLG-480H-C2800B a good driver for high-bay LED industrial lighting?
Yes. At 479W and 2800mA, it can power high-output LED high-bay fixtures in factories, warehouses, and distribution centers. The 90-305VAC universal input works with most industrial power systems, and the aluminium casing dissipates heat efficiently in warm ceiling-mounted locations.
Can I dim the HLG-480H-C2800B with an external controller?
Yes. The B suffix indicates a dimming input that accepts 1-10V, PWM, or resistance signals from an external controller. However, unlike the AB variant, this model does not include a built-in potentiometer for manual output adjustment, so all current tuning must come from the external dimming signal.
Can the HLG-480H-C2800B power LED floodlights for sports field or area lighting?
Yes. With 479W at 2800mA constant current, it can drive high-power LED floodlight modules. Its IP65 water-resistant enclosure and -40°C to +90°C operating temperature range support permanent outdoor installation in exposed athletic or commercial area lighting applications.
What is the CC voltage range on the HLG-480H-C2800B and how does it affect LED compatibility?
The CC voltage range is 85-171V. Your LED string's total forward voltage must fall within this range for the driver to regulate current properly at 2800mA. The exact number of LEDs in series depends on each LED's individual forward voltage.
Is the HLG-480H-C2800B rated for cold-weather outdoor installations?
Yes. It operates from -40°C to +90°C, so it handles extreme cold in northern climates as well as heat buildup in enclosed fixtures. The IP65 rating protects against rain, snow, and dust in sheltered outdoor mounting locations.
