Test conditions and notes13

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Please refer to "DRIVING METHODS OF LED MODULE".
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. 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.
7. 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)
8. 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.
9. 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.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
11. 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).
12. 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
14. Products sourced from the Americas regions may only have the UL, CE and UKCA logos. Please contact your MEAN WELL sales for more information.

FAQ

Can I use the HLG-240H-12B for outdoor dimmable 12V LED landscape lighting?

Yes. The HLG-240H-12B delivers 192W at 12V and accepts 1-10V, PWM, or resistance dimming signals, all while carrying an IP67 waterproof rating. This combination makes it ideal for outdoor landscape lighting where you need both weather protection and brightness control.

Is the HLG-240H-12B suitable for powering dimmable 12V LED strip on a building exterior?

Yes. With 192W at 12V and full IP67 waterproofing, the HLG-240H-12B can be mounted outdoors to drive facade-mounted 12V LED strips. The dimming input allows dynamic brightness scenes for architectural accent lighting or energy savings during off-peak hours.

Can the HLG-240H-12B drive 12V LED modules in an outdoor sign exposed to weather?

Yes. The IP67 rating handles direct rain, snow, and dust, and the 192W capacity at 12V is sufficient for large sign module arrays. The B-type dimming input lets you reduce sign brightness overnight without additional enclosure protection for the driver itself.

How many meters of 12V LED strip can the HLG-240H-12B support?

Divide 192W by your strip's power draw per meter. A strip rated at 12W/m would allow 16 meters (192W / 12W per meter = 16m). Always check your strip's rated power per meter and keep total load at or below 192W.

How does the HLG-240H-12B handle freezing temperatures in cold climates?

The HLG-240H-12B is rated for a case temperature (Tcase) of -40°C to +90°C, so it covers extreme cold in northern climates. Its IP67 waterproof seal also prevents moisture ingress from ice, snow, or freeze-thaw cycles, making it reliable for year-round outdoor installations.
