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-40H-36B to power 36V LED strips outdoors with dimming?

Yes. The HLG-40H-36B outputs 36V at up to 1.12A (40W) and includes a 1-10V/PWM dimming input for brightness control. Its IP67 waterproof rating means it can be mounted in fully exposed outdoor locations, including rain and temporary water contact.

Is the HLG-40H-36B suitable for dimmable 36V LED accent lighting?

Yes. The built-in dimming input accepts 1-10V or PWM signals, letting you integrate with common dimming controllers or building automation systems. At 40W it handles small accent lighting runs, and the constant-current mode with a 21.6-36V CC range provides stable output.

Can I power a small 36V LED sign with the HLG-40H-36B?

Yes, as long as the sign's total power draw stays within 40W. The 36V output matches standard 36V LED sign modules, and the dimming input allows day/night brightness scheduling. The IP67 rating makes it suitable for outdoor sign enclosures exposed to weather.

How many meters of 36V LED strip can the HLG-40H-36B drive?

It depends on the strip's wattage per meter. The HLG-40H-36B provides up to 40W at 36V. If your strip uses 10W/m, you could power up to 4 meters (40W / 10W per meter = 4m). Check your strip's rated power per meter and keep the combined load at or below 40W.

Can the HLG-40H-36B handle direct rain and outdoor weather exposure?

Yes. The IP67 waterproof rating means the enclosure is protected against temporary immersion in water up to 1 meter depth, so direct rain and sprinkler spray are within its capability. Its case temperature (Tcase) working range of -40°C to +80°C covers most climates.
