Test conditions and notes14
- 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. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
- 10. 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.
- 11. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
- 12. 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).
- 13. 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
- 15. 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-185H-24 to power 24V LED strip lighting in an outdoor installation?
Yes. The HLG-185H-24 outputs 24V at up to 7.8A (187.2W), and the series' metal housing with IP65/IP67 ingress protection is designed for both indoor and outdoor applications. Its -40°C to +90°C case temperature range (with load derating at higher temperatures) supports year-round outdoor use.
Is the HLG-185H-24 suitable for powering 24V LED channel letter signage?
Yes. With 187.2W at 24V, the HLG-185H-24 provides ample power for channel-letter signs, light boxes, and cabinet signs using 24V LED modules. Its wide 90-305VAC input suits most mains supplies, and the IP65/IP67-rated housing allows mounting inside outdoor sign enclosures.
Can the HLG-185H-24 drive 24V LED cove or accent lighting in commercial spaces?
Yes. The 187.2W capacity at 24V is well-suited for runs of cove, accent, or indirect lighting using 24V LED strip or modules. The constant-current mode with a CC voltage range of 12-24V maintains stable output across varying LED forward voltages. The datasheet lists a typical life expectancy of over 62,000 hours at a Tcase of about 75°C or less.
How many meters of 24V LED strip can the HLG-185H-24 power?
Divide 187.2W by your strip's wattage per meter. For example, a 24V strip rated at 14.4W/m would allow about 13 meters (187.2W / 14.4W per meter = 13m). Always check your strip's rated power per meter and keep the total load at or below 187.2W.
Can the HLG-185H-24 be mounted in a location fully exposed to rain and dust?
Yes. The HLG-185H series has a metal housing with IP65/IP67 ingress protection that the datasheet says suits outdoor applications, and waterproof M12/M15 connectors are available for the output cable in wet locations. Follow MEAN WELL's IP installation cautions in the user manual. The case temperature range is -40°C to +90°C.
What are the differences between the HLG-185H-24, 24A, 24AB, and 24B models?
All four share 187.2W / 24V / 7.8A core specs and the same 228 x 68 x 38.8 mm housing. The base HLG-185H-24 has fixed output. The -24A adds output voltage/current adjustment via built-in potentiometer. The -24AB adds both adjustment and 3-in-1 (1-10V/PWM/resistance) dimming input. The -24B provides dimming input only, without the potentiometers.
