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. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
8. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
9. 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).
10. 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
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-240H-C1050A to drive high-power LED downlights in a commercial space?

Yes. The HLG-240H-C1050A delivers 1050mA constant current at up to 249.9W, making it well suited for high-output commercial downlights and recessed fixtures. The CC voltage range of 119-238V accommodates a wide variety of series LED configurations, and the adjustable output lets you fine-tune current to your fixtures' specifications.

Is the HLG-240H-C1050A a good choice for LED grow light panels?

It can work for grow lights whose LED arrays are designed for 1050mA drive current and whose total forward voltage falls within 119-238V. At 249.9W it provides substantial power for medium-to-large LED panels. The adjustable output helps calibrate light intensity, and the working humidity rating of 20-95% RH (non-condensing) covers typical growing environments.

Can I power large LED signage arrays with the HLG-240H-C1050A?

Yes. At 1050mA and up to 249.9W, this driver handles large channel letter arrays and illuminated sign panels whose series LED string voltage totals between 119V and 238V. The adjustable output lets you dial in the current for optimal LED brightness and longevity.

How do I determine the right LED string length for the HLG-240H-C1050A?

Sum the forward voltages of the individual LEDs in your series string. The total must fall within the CC voltage range of 119-238V. The driver provides a steady 1050mA regardless of the exact voltage within that range. The adjustable output allows minor current trimming to optimize performance for your specific LEDs.

Can the HLG-240H-C1050A be installed in a damp or dusty location?

Yes. The HLG-240H-C series is rated IP65 or IP67 depending on type, so covered outdoor areas, dusty workshops, and semi-exposed canopy locations are acceptable. For heavily exposed installations, check the IP rating of your specific type and follow MEAN WELL's IP installation cautions in the user manual.
