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-54B with a dimmer to control outdoor 54V LED landscape lighting?

Yes. The HLG-100H-54B supports dimming via 1-10V, PWM, and resistance signals, and the HLG-100H series' IP65/IP67 metal-housing design suits outdoor landscape lighting installations. You can dim the output to create different lighting scenes while the driver handles up to 95.58W.

Is the HLG-100H-54B suitable for dimmable 54V LED parking lot fixtures?

It can drive 54V LED parking lot fixtures drawing up to 95.58W with smooth dimming control. The series' IP65/IP67 metal-housing design and -40°C to +80°C case temperature (Tcase) range suit outdoor mounting, and dimming allows energy savings during low-traffic hours.

Can I power dimmable 54V LED bollard lights with the HLG-100H-54B?

Yes, provided total load stays at or below 95.58W. The HLG-100H-54B delivers 54V at up to 1.77A in constant-current mode with dimming capability. The series' IP65/IP67 metal-housing design suits ground-level bollard fixtures exposed to rain or sprinklers; use a waterproof connector on the output cable.

How many meters of 54V LED strip can the HLG-100H-54B handle?

The HLG-100H-54B provides up to 95.58W at 54V. Divide that by your strip's rated wattage per meter to find the maximum run. For example, a strip rated at 7W/m would allow approximately 13.6 meters (95.58W / 7W per meter). Always check your strip's rated power per meter and keep total load within the rated power.

Can the HLG-100H-54B be installed underground or in areas prone to flooding?

The HLG-100H series has a metal housing with IP65/IP67 ingress protection and is designed for outdoor applications, with waterproof connectors on the cable connections. The sheet does not state a submersion rating for this type, so confirm its exact IP rating before using in-ground boxes or flood-prone locations, and do not install it permanently submerged.

What does the 'B' suffix mean on the HLG-100H-54B versus the base HLG-100H-54?

The 'B' suffix indicates the model includes a dimming function input (supporting 1-10V, PWM, and resistance dimming). The base HLG-100H-54 has fixed output with no dimming. Both deliver 95.58W at 54V and 1.77A.
