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 80℃ 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-100H-42 to power 42V LED street or pathway lighting outdoors?

Yes. The HLG-100H-42 delivers 42V at up to 2.28A (95.76W rated power), and the HLG-100H series' metal housing with IP65/IP67 ingress protection is designed for indoor and outdoor applications such as street lights, bollard lights, or pathway luminaires. Its -40°C to +80°C case temperature (Tcase) range also handles harsh seasonal temperature swings.

Is the HLG-100H-42 suitable for powering 42V LED high-bay warehouse lights?

It can drive 42V high-bay LED fixtures provided the total load stays at or below 95.76W. The constant-current mode with a 21-42V region ensures stable output for consistent illumination, and the fanless metal housing cools by free air convection in warm industrial environments.

Can I run 42V LED signage modules from the HLG-100H-42?

Yes. The HLG-100H-42 provides a steady 42V output at up to 95.76W, which suits medium-sized LED sign cabinets and channel letter arrays. The series' IP65/IP67 metal-housing design fits outdoor sign housings where moisture exposure is likely; use a waterproof connector on the output cable.

How many meters of 42V LED strip can the HLG-100H-42 support?

Divide the driver's 95.76W rated power by your strip's rated wattage per meter. For example, a 42V strip rated at 8W/m would allow up to about 11.9 meters (95.76W / 8W per meter). Always check your strip's rated power per meter and keep total load within the rated power.

Can the HLG-100H-42 handle fully exposed outdoor installations with rain and snow?

The HLG-100H series is designed for outdoor applications: its metal housing has IP65/IP67 ingress protection, and with a waterproof connector on the output cable it can operate in dry, damp, wet or outdoor environments such as rooftop fixtures and garden lighting. The series comes in IP65 and IP67 versions, so confirm the rating of this exact type for fully exposed sites.

What are the differences between the HLG-100H-42, 42A, 42AB, and 42B variants?

All four share the same 95.76W, 42V, 2.28A core output. The base HLG-100H-42 has fixed output. The -42A adds built-in potentiometers to adjust output voltage (38-46V) and current (1.4-2.28A). The -42AB offers both adjustable output and 3-in-1 dimming. The -42B provides dimming without adjustable output. The series comes in IP65 and IP67 versions; check the rating of each type.
