Type: HL

Test conditions and notes12

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.
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 point (or TMP, per DLC), is about 80℃ 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

FAQ

Can I use the HLG-150H-42B with a PWM dimmer to control outdoor 42V LED flood lights?

Yes. The HLG-150H-42B accepts 1-10V and PWM dimming signals, allowing smooth brightness control of 42V LED flood lights. Its IP67 waterproof rating means the driver can be installed outdoors in fully exposed conditions; protect the dimming and output wire connections with waterproof connectors or a cable joiner.

Is the HLG-150H-42B suitable for dimmable 42V LED street lighting?

Yes. At 151.2W and 42V with dimming input, it can drive 42V LED street light fixtures with brightness scheduling via a 1-10V controller. The IP67 rating and -40°C to +90°C case-temperature (Tcase) range make it reliable for pole-mounted outdoor installations in all weather conditions.

Can the HLG-150H-42B power dimmable 42V LED landscape lighting?

Yes. The 151.2W output at 42V with dimming capability is well suited for landscape accent lights, pathway lights, or garden feature lighting where brightness levels need to change throughout the evening. The IP67 waterproof rating handles direct ground-level moisture and rain exposure.

How many meters of 42V LED strip can the HLG-150H-42B handle?

Divide the 151.2W rated power by your strip's rated power per meter. For instance, a 42V strip consuming 20W/m could run about 7.5 meters (151.2W / 20W per meter). Check your strip's rated power per meter and keep the total load at or below 151.2W for reliable operation.

Can the HLG-150H-42B be used in locations with standing water or temporary flooding?

The IP67 rating means the enclosure is protected against temporary immersion in water. It can handle puddles, heavy rain, and brief flooding events, making it suitable for low-mounted outdoor installations near ground level or in drainage-prone areas.
