Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
7. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
8. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
11. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can I use the HLG-120H-C500B to drive dimmable LED downlights in a commercial space?

Yes. The HLG-120H-C500B provides 500mA constant current with up to 150W and a CC voltage range of 150-300V. The B suffix indicates it includes a 1-10V/PWM dimming input, allowing you to pair with a compatible dimmer for brightness control across LED downlight arrays in offices, retail spaces, or lobbies.

Is the HLG-120H-C500B suitable for powering LED modules in backlit signage with dimming control?

Yes. At 500mA constant current and a voltage range of 150-300V, it can drive series-connected LED strings in lightbox signs or illuminated displays. The dimming input allows you to reduce brightness for nighttime operation or energy management. The exact number of LEDs depends on each module's forward voltage.

Can the HLG-120H-C500B power high-voltage LED arrays in an architectural cove lighting installation?

Yes. With 150W at 500mA and a CC range of 150-300V, it works well for driving high-voltage LED arrays in cove lighting, wall wash, or other architectural applications. The series' IP65/IP67 rating is suitable for indoor installations including those in damp locations. The 3-in-1 dimming input (1-10V, PWM or resistance) supports dynamic scene control.

Does the HLG-120H-C500B allow output current adjustment?

No. The B suffix means this model includes a dimming input (1-10V/PWM) but does not have a potentiometer for output current adjustment. If you need to adjust the baseline current to match a specific LED load, consider the C500A (adjustment only) or C500AB (adjustment plus dimming).

Can the HLG-120H-C500B operate reliably in cold environments like a walk-in freezer?

The HLG-120H-C500B works at a case temperature (Tcase) down to -40°C (range -40°C to +90°C), so it can handle the extreme cold found in walk-in freezers or cold storage facilities. Its working humidity is rated 10-95% RH non-condensing, so mount it where condensation and frost cannot form on the driver, and keep the case within its +90°C maximum.

How does the constant current output of the HLG-120H-C500B differ from constant voltage HLG-120H models?

The HLG-120H-C500B is a constant current driver that maintains a steady 500mA regardless of load voltage (within the 150-300V range). A constant voltage driver maintains a fixed output voltage and lets current vary with the load. Constant current drivers are used for LEDs wired in series strings, while constant voltage drivers are for parallel-connected LED strips or modules.
