Product Overview

The Universal Lighting 188612.02 is a 50-watt electronic HID ballast engineered as a direct upgrade path from magnetic metal halide ballasts in commercial and industrial fixtures. Operating on universal 120V–277V input with ±10% voltage tolerance, this ballast eliminates the need to stock multiple voltage-specific SKUs for multi-circuit facilities.

The eHID platform uses microprocessor control to deliver stable, flicker-free lamp operation at high frequency — eliminating the stroboscopic effect common with magnetic ballasts. Active power factor correction keeps the power factor above 0.95, reducing reactive current and supporting energy code compliance. End-of-Life (EOL) protection shuts the ballast down safely when the lamp reaches end of service life, protecting both the fixture and the circuit.

The low-profile feet-mount design with side lead exit slides directly into standard ballast channels and simplifies installation in replacement and retrofit applications. At 5.51 x 3.62 x 1.57 inches, this is a compact unit that fits a wide range of commercial fixture housings.

Why Choose This Product

• 20%+ energy savings over magnetic: Converts more input power to useful lamp output, directly reducing operating costs in continuous-burn commercial applications.
• Universal 120–277V input: A single SKU covers all standard North American commercial distribution voltages — ideal for facilities with mixed circuits.
• Dual ANSI code support (M148 / M110): Operates both common 50W ceramic metal halide ANSI types, expanding fixture and lamp compatibility.
• Microprocessor control: Precisely regulates lamp power for consistent light output and extended lamp life throughout the burn cycle.
• Flicker-free high-frequency operation: Eliminates the stroboscopic effect from 60Hz magnetic ballasts — critical in retail, food service, and manufacturing environments.
• Active power factor correction: Reduces reactive load on distribution panels and supports compliance with utility and energy code requirements.
• EOL protection: Automatic shutdown when lamp reaches end of life prevents fixture damage and potential fire hazards.
• UL Type 1 Outdoor Rated: Suitable for installation in outdoor-rated and exposed fixture applications.
• RoHS compliant: Meets European and domestic environmental standards for restricted hazardous substances.

Always verify ANSI code, lamp wattage, and mounting configuration match your fixture before installation.

Applications

The Universal 188612.02 50W eHID ballast is suited for commercial, industrial, and outdoor lighting applications running 50W ceramic metal halide sources:

• Retail and display lighting – Track heads, accent fixtures, and recessed downlights running 50W CMH lamps where flicker-free, color-accurate light is required.
• Hospitality and restaurant lighting – Quiet, high-frequency operation eliminates distracting stroboscopic effects in dining and lobby environments.
• Office and commercial interiors – Low-profile design fits tight fixture channels; silent operation suits open-plan and quiet workspace environments.
• Industrial and warehouse facilities – Magnetic ballast replacement upgrade for high-bay and low-bay 50W CMH fixtures.
• Outdoor and site lighting – UL Type 1 Outdoor rating supports installation in wet and exposed fixture housings.
• Retrofit and replacement programs – Universal voltage and dual ANSI code support reduce SKU complexity for facility maintenance teams.

Replacing Your Current Metal Halide Ballast?

Confirm the following before ordering to ensure a direct-fit replacement:

• ANSI code: This ballast supports M148 and M110 ANSI codes. Verify your existing lamp and ballast carry one of these codes.
• Lamp wattage: This ballast drives one 50W CMH lamp. Do not use with 35W, 70W, or other wattage lamps even if the base type appears compatible.
• Circuit voltage: Universal 120V–277V input covers all standard commercial voltages within ±10% tolerance.
• Mounting style: This is a feet-mount ballast with side lead exit. Verify your fixture housing accepts this configuration.
• Fixture compatibility: This is an electronic ballast. Verify the fixture is rated for electronic ballast operation. Older fixtures wired exclusively for magnetic ballasts may require wiring modification.
• Outdoor use: UL Type 1 Outdoor Rated — confirm your fixture’s outdoor rating matches or exceeds this classification for wet or damp location installations.
