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-12B with a dimmer for outdoor 12V LED landscape strip lighting?

Yes. The HLG-185H-12B accepts 1-10V, PWM and resistance dimming signals and has a metal housing with IP65/IP67 ingress protection designed for outdoor applications, making it a good fit for landscape lighting. It delivers up to 156W at 12V (13A).

Is the HLG-185H-12B a good choice for dimmable 12V LED pathway or garden lighting?

Yes. With 156W capacity at 12V, IP65/IP67 ingress protection, and dimming input, the HLG-185H-12B can power long runs of 12V LED pathway lights while allowing brightness reduction for evening or late-night energy savings. The -40°C to +90°C case temperature range (with derating at higher temperatures) handles seasonal extremes.

Can the HLG-185H-12B drive 12V LED strip for an outdoor sign that needs brightness control?

Yes. At 156W and 13A on the 12V output with dimming capability, it can handle a substantial amount of 12V LED sign modules. The dimming input lets you reduce brightness at night to comply with local sign ordinances or save energy, and the IP65/IP67-rated metal housing is designed for outdoor use.

How does the HLG-185H-12B compare to the HLG-185H-12AB for outdoor dimmable LED projects?

Both deliver 156W at 12V with a 1-10V/PWM/resistance dimming input. The -12B lacks an output adjustment potentiometer, while the -12AB adds potentiometers for manual output voltage and current trimming. The datasheet notes that A/AB types need to be considered for built-in use to comply with UL Type HL, so choose the -12B when no manual adjustment is needed.

Can the HLG-185H-12B operate year-round in an exposed outdoor location with extreme weather?

Yes. Its metal housing with IP65/IP67 ingress protection and -40°C to +90°C case temperature range are designed for indoor and outdoor installation. At high temperatures, including direct sun exposure, the output load must be derated per the datasheet's load-vs-temperature curve.
