120 Watt Mean Well LED Driver | HLG-120H-24B

Product Overview

The 120 Watt Mean Well LED Driver | HLG-120H-24B is a constant voltage power supply designed for use with compatible LED fixtures. It provides regulated 24V DC output at up to 120 watts, supporting both new installations and field replacements. The compact, surface-mountable form factor is suited for integration within fixture housings or remote mounting in electrical enclosures.

This driver is commonly specified for sports field and stadium lighting systems, as well as other commercial and industrial lighting applications requiring reliable, UL-certified power delivery. The IP65 rating supports use in damp or dusty environments where exposure to moisture or particulates is expected.

Core Performance and Output

This driver delivers a maximum output of 120 watts at 24V DC, operating from a universal input voltage range of 100V to 277V AC at 50/60 Hz. It maintains stable output for consistent fixture performance and supports a range of LED loads within its rated capacity. The electrical design is suitable for both indoor and outdoor environments where IP65 protection is required.

Output is regulated for compatibility with LED fixtures requiring 24V DC input. Excessive loading beyond 120W will result in driver protection mode or reduced output. For applications with high inrush or large fixture arrays, confirm total load does not exceed driver capacity.

Adjustability and Control Options

The HLG-120H-24B model includes built-in dimming capability via 0-10V control wiring. This allows for integration with compatible dimming systems or controls, supporting variable light output as required by the application. Dimming range and response are determined by fixture compatibility and control system design.

No onboard manual adjustment is provided; all control is external. Ensure control wiring is properly terminated and isolated from AC input to prevent interference or malfunction.

Longevity and Reliability

This driver is engineered for long-term operation in demanding environments. The IP65 enclosure protects internal components from dust and water spray, supporting use in both indoor and outdoor locations. Mean Well drivers are recognized for stable output and thermal management, reducing the risk of premature failure.

Expected service life aligns with typical LED fixture maintenance cycles. The 3-year warranty covers manufacturing defects under normal operating conditions. For installations in high-heat or poorly ventilated locations, monitor enclosure temperature to avoid derating or reduced lifespan.

Build Quality and Physical Characteristics

The driver features a sealed, compact aluminum housing measuring 9.41 inches by 7.13 inches. The enclosure is designed for surface mounting and includes integrated mounting tabs for secure attachment to flat surfaces or within fixture assemblies. All wiring connections are made via pigtail leads for straightforward integration.

UL certification and IP65 rating confirm suitability for commercial and industrial environments where exposure to dust, moisture, or incidental water spray is present. The housing provides mechanical protection and electrical isolation for safe operation.

Where This Product Fits Best

This driver is intended for use in commercial and industrial lighting systems where regulated 24V DC power is required for fixture operation or retrofit. It is commonly used in environments where fixture repair, emergency backup integration, or lighting maintenance support is needed. The IP65 rating supports deployment in both indoor and outdoor locations with exposure to dust or water spray.

• fixture repair and replacement
• emergency backup integration
• lighting maintenance support
• retrofit support
• code compliance upgrades
• emergency egress support
• service stock for maintenance teams
• field repair projects

Environmental characteristics include resistance to dust and water spray, with suitability for damp or semi-exposed locations. Not intended for full submersion or environments requiring explosion-proof or marine-rated equipment.

Installation and Long-Term Use

Surface mounting is supported via integrated tabs on the enclosure. The compact design allows for installation within fixture housings, electrical cabinets, or directly to structural surfaces. All wiring is completed using pigtail leads; confirm proper strain relief and enclosure sealing for outdoor or damp locations.

Routine inspection of wiring connections and enclosure integrity is recommended as part of scheduled maintenance. For emergency backup integration, verify compatibility with fixture and control system requirements. Replacement is straightforward due to standard form factor and mounting pattern.

How This Fixture Is Commonly Used

This driver is typically installed as a replacement component during fixture repair, as part of emergency backup system integration, or for supporting retrofit projects where existing drivers have failed or require upgrade. Mounting location is determined by fixture design and site requirements, with surface mounting being the most common approach.

Spacing and layout are dictated by fixture placement and electrical distribution. When supporting multiple fixtures or high-output arrays, ensure total load does not exceed driver capacity. Using a single driver for multiple fixtures may reduce component count but can complicate troubleshooting and increase risk of total outage if the driver fails.

Safety, Certifications, and Warranty

This driver is UL certified and meets IP65 ingress protection standards. The enclosure provides electrical isolation and mechanical protection for safe operation in commercial and industrial environments. All installations must comply with local electrical codes and manufacturer guidelines.

A 3-year warranty is provided against manufacturing defects. Warranty coverage is contingent on proper installation and operation within rated specifications. For emergency backup or code compliance applications, confirm all system components meet required standards.
