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-80H-42 to power 42V LED modules for outdoor signage?

Yes. The HLG-80H-42 outputs 42V at up to 1.95A (80W) with an IP67 waterproof rating, making it suitable for outdoor channel letters, cabinet signs, and light boxes that use 42V LED modules. Its wide 90-305VAC input works with most commercial mains voltages worldwide.

Is the HLG-80H-42 suitable for powering 42V LED grow lights?

Yes, provided the grow light operates at 42V and draws no more than 80W. The HLG-80H-42 runs in constant-current mode with a CC region of 25.2-42V, which suits many horticultural LED boards. It is IP67 rated, with a working humidity rating of 20-95% RH non-condensing.

Can I run 42V LED panel lights from the HLG-80H-42 in a warehouse?

Yes. At 80W and 42V output, the HLG-80H-42 can drive 42V panel lights as long as their combined load stays within 80W. Its IP67-rated metal housing suits the dust and moisture common in warehouse environments.

How many meters of 42V LED strip can the HLG-80H-42 support?

Divide 80W by your strip's rated power per meter. For example, if your 42V strip draws 12W/m, you can run about 6.6 meters (80W / 12W per meter = 6.67m). Always check your strip's rated power per meter and keep total load at or below 80W.

Can the HLG-80H-42 be mounted outdoors in freezing winter conditions?

Yes. Its rated case temperature (Tcase) range is -40°C to +80°C, so it can operate in extreme cold. Combined with its IP67-rated metal housing, designed for indoor and outdoor applications, it suits year-round outdoor installations, including winter conditions.
