Frequently Asked Questions
Can I use the HLG-320H-C3500B to drive high-power LED downlights in a commercial building?
Yes. The HLG-320H-C3500B delivers 3500mA constant current at up to 318.5W, making it capable of powering high-output LED downlight fixtures. The LED string's total forward voltage must fall within the 46-91V CC voltage range. Its IP65 rating allows installation in damp or dusty mechanical rooms.
Is the HLG-320H-C3500B suitable for powering LED arrays in large illuminated signage?
It can work for signage modules that require high drive current at relatively low voltage. At 3500mA with a CC range of 46-91V, it is best suited for short series strings of high-current LEDs rather than long strings of low-current modules. Confirm that your sign modules' combined forward voltage stays within 46-91V.
Can I dim the HLG-320H-C3500B for nighttime brightness reduction in outdoor LED fixtures?
Yes. The B suffix indicates a built-in 1-10V/PWM dimming input, allowing external dimming controllers or building automation systems to reduce output. This is useful for scheduling lower brightness at night in parking lot or pathway lighting applications.
How many LEDs can I run in series with the HLG-320H-C3500B?
The exact count depends on each LED's forward voltage. The driver operates in constant current mode at 3500mA with a CC voltage range of 46-91V, so you need to sum the forward voltages of your LEDs and verify the total stays within that range. Higher forward voltage LEDs will allow fewer in series; lower forward voltage LEDs will allow more.
Can I install the HLG-320H-C3500B in a semi-exposed outdoor location?
Yes. Its IP65 rating protects against dust ingress and low-pressure water jets, making it suitable for sheltered outdoor enclosures, soffits, or ventilated housings. It is not rated for full submersion. For installations requiring submersion protection, consider the IP67-rated HLG-320H-C3500DA.
What is the difference between the HLG-320H-C3500B and the HLG-320H-C3500A?
Both share the same 318.5W, 3500mA, 46-91V constant current specs and IP65 rating. The -C3500A includes a built-in potentiometer for output current adjustment but no dimming signal input. The -C3500B provides a 1-10V/PWM dimming input instead. The -C3500AB combines both features, and the -C3500DA adds DALI dimming with IP67 protection.
