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-C700B for dimmable LED high-bay or troffer fixtures?

Yes. The HLG-120H-C700B delivers 700mA constant current at up to 150.5W with a CC voltage range of 107-215V. The B suffix means it includes a 1-10V/PWM dimming input for brightness control, making it well-suited for high-bay or troffer lighting where occupancy sensors or daylight harvesting systems adjust light levels.

Is the HLG-120H-C700B suitable for driving LED modules in dimmable signage applications?

Yes. At 700mA constant current and a voltage range of 107-215V, it can power series-connected LED signage modules. The dimming input allows nighttime brightness reduction for energy savings or light pollution compliance. The number of LEDs you can wire in series depends on each LED's forward voltage — ensure the total falls within 107-215V.

Can the HLG-120H-C700B power LED modules in a dimmable retail display lighting system?

Yes. The 700mA constant current output is common for mid-power LED modules used in retail spotlights, track lighting modules, and display case lighting. The 1-10V/PWM dimming input lets store staff adjust brightness throughout the day. At 150.5W, it can handle substantial lighting loads for a single zone or fixture group.

Does the HLG-120H-C700B have a potentiometer for adjusting the output current?

No. The B suffix indicates this model has a 3-in-1 dimming input (1-10V, PWM or resistance) but no built-in potentiometer for output current adjustment, which the sheet lists for A/AB types only. The rated output is 700mA, and lower levels are set only through the dimming input. If you need to adjust the baseline current to match a specific LED module, choose the C700A (adjustment only) or C700AB (adjustment plus dimming).

Can the HLG-120H-C700B handle the temperature extremes inside an outdoor sign cabinet?

Yes. The HLG-120H-C700B works at a case temperature (Tcase) of -40°C to +90°C, with load derating at higher temperatures per the output load vs temperature curve, so it can handle winter cold and heat build-up inside sign cabinets within those limits. The series' IP65/IP67 rating protects against dust and moisture ingress typical of outdoor sign enclosures. Ensure adequate ventilation to keep the case at or below +90°C.

How does the 700mA constant current output differ from a constant voltage driver for LED applications?

The HLG-120H-C700B maintains a steady 700mA output current regardless of the load voltage (within 107-215V), which is ideal for LEDs wired in series. Constant voltage drivers maintain a fixed voltage and let current vary, which suits parallel-connected LED strips. If your LED modules specify a drive current (e.g., 700mA), a constant current driver like this one ensures consistent brightness and prevents overcurrent damage.
