Frequently Asked Questions
Can I use the HLG-320H-C1050DA with a DALI lighting control system?
Yes. The DA suffix indicates built-in DALI (Digital Addressable Lighting Interface) protocol support. You can integrate this driver directly into a DALI bus for centralized dimming control, scene management, and status monitoring. It delivers 1050mA constant current at up to 320.25W across a 152-305V range.
Is the HLG-320H-C1050DA suitable for outdoor LED fixtures fully exposed to rain?
Yes. Unlike the IP65-rated A, AB, and B variants, the C1050DA carries an IP67 waterproof rating, meaning it can withstand temporary submersion up to 1 meter. This makes it suitable for ground-recessed fixtures, open-air pole mounts, or locations where standing water and heavy rain are expected.
Can I use the HLG-320H-C1050DA for smart building LED lighting with automated scheduling?
Yes. DALI protocol enables individual fixture addressing, group dimming, and scheduled scene changes through a DALI controller or building automation system. The 320.25W output at 1050mA handles demanding commercial fixtures, and the IP67 rating allows placement in both indoor and outdoor locations.
Is the HLG-320H-C1050DA a good fit for LED tunnel or underpass lighting on a DALI bus?
Yes. Tunnel lighting often requires DALI control for daylight-adaptive dimming at entry and exit zones. This driver provides 1050mA constant current at up to 320.25W, and its IP67 waterproof rating handles the moisture and condensation common in tunnel environments. The -40°C to +85°C operating range covers seasonal extremes.
What is the LED string voltage requirement for the HLG-320H-C1050DA?
The constant-current operating range is 152-305V at 1050mA. configure your LEDs in series so the combined forward voltage falls within this window. The exact LED count depends on each LED's forward voltage — sum them and verify the total is between 152V and 305V.
How does the IP67 rating on the HLG-320H-C1050DA compare to the IP65 on other C1050 variants?
IP65 protects against dust and low-pressure water jets, suitable for sheltered outdoor or indoor locations. IP67 adds protection against temporary submersion in water up to 1 meter deep. Choose the C1050DA (IP67) for installations directly exposed to heavy rain, flooding risk, or ground-level mounting where pooling water is possible.
