Frequently Asked Questions
Can I use the HLG-320H-C3500AB for dimmable LED high-bay fixtures in a distribution center?
Yes. The HLG-320H-C3500AB delivers 3500mA constant current at 318.5W with both output adjustment and dimming input (1-10V, PWM, or resistance). This makes it ideal for high-bay luminaires in warehouses and distribution centers where occupancy-based or daylight-responsive dimming reduces energy costs.
Is the HLG-320H-C3500AB a good choice for dimmable LED grow lights?
Yes. At 3500mA and 318.5W, it provides high drive current for demanding grow light modules in the 46-91V range. The adjustable potentiometer sets the baseline output, while the dimming input allows automated intensity changes for different photoperiods or growth stages without rewiring.
Can the HLG-320H-C3500AB power dimmable LED floodlights for an outdoor event venue?
Yes, for floodlight modules operating within the 46-91V CC range at 3500mA. The dimming input supports scene control from a lighting console. Note that its IP65 rating handles dust and water spray, but the driver should be mounted in a protected location or enclosure for full rain exposure.
What is the difference between the HLG-320H-C3500A and the HLG-320H-C3500AB?
Both share the same 318.5W / 95V / 3500mA core specs, 46-91V CC range, IP65 rating, and built-in output adjustment potentiometer. The -AB adds a dimming input (1-10V, PWM, or resistance) for external brightness control. Choose the -A if you only need fixed output adjustment, or the -AB if you need dynamic dimming capability.
How many LEDs can the HLG-320H-C3500AB drive at 3500mA?
The number depends on each LED's forward voltage. With a CC voltage range of 46-91V, divide your target string voltage by the individual LED forward voltage. The driver will regulate at 3500mA constant current as long as the total string voltage remains within 46-91V.
Can the HLG-320H-C3500AB withstand freezing outdoor conditions in a sheltered enclosure?
Yes. Its -40°C to +85°C operating temperature range covers extreme cold without requiring a heater. The IP65 rating keeps out dust and water spray, making it safe for sheltered outdoor enclosures such as pole-mounted cabinets, canopy housings, or covered equipment rooms.
