Frequently Asked Questions

Can I use the HLG-120H-C1050A to drive high-power LED downlights?

Yes. The HLG-120H-C1050A delivers a constant 1050mA across a 74-148V output range, making it well suited for high-power COB or multi-chip LED downlights that operate in that voltage window. At 155.4W it can handle substantial ceiling-mounted fixtures, and the adjustable output lets you trim current to match the exact LED module requirements.

Is the HLG-120H-C1050A a good fit for driving LED signage modules in series?

Yes, provided your series string of signage modules has a combined forward voltage between 74V and 148V. The driver delivers a regulated 1050mA constant current, so it maintains consistent brightness across the string. Its wide 90-305VAC input also accommodates varying mains supplies found in commercial sign installations.

Can the HLG-120H-C1050A power LED arrays in a warehouse or industrial bay light?

Yes. With 155.4W at 1050mA and IP65 water resistance, the HLG-120H-C1050A is suitable for industrial high-bay or warehouse LED fixtures. The aluminium casing handles the -40°C to +90°C operating range typical of unheated facilities, and the adjustable output allows fine-tuning to the specific LED array voltage.

How many LEDs can the HLG-120H-C1050A drive in a series string?

The number of LEDs depends on each LED's forward voltage. The HLG-120H-C1050A operates in constant current mode at 1050mA with a CC voltage range of 74-148V, so the total forward voltage of your series string must fall within that window. Divide your target voltage by the individual LED forward voltage to determine how many LEDs can be connected in series.

Can the HLG-120H-C1050A be installed in a covered outdoor location like a parking canopy?

Yes. Its IP65 rating protects against dust ingress and low-pressure water jets, making it appropriate for covered outdoor areas such as parking canopies, building soffits, and covered walkways. For fully exposed installations with direct rain or standing water, an IP67-rated driver would be a better choice.

What is the difference between the HLG-120H-C1050A, C1050AB, and C1050B models?

All three share the same 155.4W, 1050mA, 74-148V constant current output and IP65 rating. The C1050A (this model) has adjustable output via a built-in potentiometer but no dimming input. The C1050AB adds both adjustment and a 1-10V/PWM dimming input. The C1050B has the dimming input only with no potentiometer adjustment.
