Frequently Asked Questions
Can I use the HLG-120H-C350B to drive high-voltage LED string arrays for commercial signage?
Yes. The HLG-120H-C350B operates in constant current mode at 350mA with an output voltage range of 215-430V, making it well-suited for long series strings of LEDs used in channel letters, lightbox signage, or large illuminated displays. The number of LEDs you can run in series depends on each LED's forward voltage, so verify your total string voltage falls within the 215-430V range.
Is the HLG-120H-C350B suitable for powering LED downlights in a covered outdoor canopy?
Yes. With 150.5W of power at a regulated 350mA and an IP65 water-resistant rating, it can reliably drive high-voltage LED downlight arrays in sheltered outdoor environments such as canopies, carports, or building overhangs. The -40°C to +90°C operating temperature range also handles seasonal temperature swings.
Can the HLG-120H-C350B be used with a dimmer for adjustable-brightness LED fixtures?
Yes. The B suffix indicates this model includes a 1-10V/PWM dimming input, so you can pair with a compatible dimmer to control LED brightness without needing the output voltage adjustment feature found on A-suffix models. This makes it a good choice for applications where brightness needs to change but the LED load is fixed.
Is the HLG-120H-C350B appropriate for driving LED modules in an outdoor parking garage?
Yes. The IP65 rating protects against dust ingress and low-pressure water jets, which covers typical parking garage conditions. At 150.5W and 350mA constant current with a CC voltage range of 215-430V, it can power high-voltage LED modules used in garage ceiling fixtures. The aluminium casing aids heat dissipation in enclosed mounting locations.
What operating conditions does the HLG-120H-C350B handle for outdoor installations?
The HLG-120H-C350B is rated IP65 for dust-tight and water-jet protection, and operates from -40°C to +90°C. This makes it suitable for sheltered outdoor and semi-exposed installations, though it is not designed for submersion. For fully submerged or extreme wet applications, an IP67-rated driver would be more appropriate.
What are the differences between the HLG-120H-C350A, C350AB, and C350B models?
All three share the same 150.5W, 350mA, 215-430V constant current specs and IP65 rating. The C350A offers output current adjustment via built-in potentiometer. The C350AB combines both output adjustment and 1-10V/PWM dimming input. The C350B provides 1-10V/PWM dimming input only, without output adjustment. Choose based on whether you need adjustability, dimmability, or both.
