Installation Requirements & Guidelines

Pre-Installation Checklist

• Verify Lamp Compatibility: Confirm lamp ANSI code matches M98 or M143 rating
• Check Input Voltage: Ensure 120V supply voltage (NOT compatible with 208V, 240V, or 277V)
• Confirm Fixture Rating: Verify fixture is rated for electronic ballasts
• Review Wiring Diagram: Follow wiring diagram on ballast label exactly
• Inspect Enclosure: Ensure junction box and fixture provide adequate ventilation

Critical Installation Notes

• Mount ballast in well-ventilated location to prevent overheating
• Do not exceed maximum ambient temperature of 50°C (122°F)
• Use minimum 18 AWG wire for all connections (THHN rated for high temperature)
• Ensure all wire connections are secure and properly insulated
• Ground ballast enclosure according to NEC requirements
• For outdoor installations, ensure fixture provides NEMA 3R or better protection
• Install within rated recessed fixture clearances if used in downlights

Safety Warnings

• ⚠️ Electric Shock Hazard: Disconnect power before installation or servicing
• ⚠️ Incompatible Lamps: NOT for use with High Pressure Sodium (HPS) lamps - will damage ballast
• ⚠️ Overheating Risk: Do not cover ballast or restrict airflow around enclosure
• ⚠️ Voltage Mismatch: 120V only - do not connect to 208V, 240V, or 277V circuits

Electronic vs. Magnetic Ballast Advantages

GE UltraMax electronic ballasts offer significant performance benefits compared to traditional magnetic (core-coil) ballasts:

• Energy Efficiency: 10-15% lower energy consumption reduces operating costs
• Lighter Weight: 60% lighter than magnetic ballasts - easier installation
• Cooler Operation: Less heat generation extends fixture and lamp life
• Faster Restrike: Quicker lamp restart after power interruptions
• Cold Weather Starting: Reliable ignition down to -20°C vs. -30°C for magnetic
• Lamp Life Protection: End-of-life shutdown prevents lamp cycling damage
• Compact Size: Smaller footprint fits more fixture types including recessed

Maintenance & Troubleshooting Guide

Routine Maintenance

• Inspect ballast and fixture quarterly for signs of overheating or damage
• Clean fixture lenses and reflectors to maintain light output
• Check wire connections annually for tightness and corrosion
• Replace lamps at 75% of rated life to prevent end-of-life ballast shutdown
• Keep ballast enclosure area clear of debris and obstructions

Common Troubleshooting

Lamp Won't Start

• Verify power supply is energized (120V)
• Check lamp is properly seated in socket
• Confirm lamp ANSI code matches M98 or M143
• Test with known good lamp to rule out lamp failure
• Inspect wire connections for looseness or damage

Lamp Flickers or Cycles On/Off

• Replace lamp - likely at end of rated life
• Check for loose connections at lamp socket
• Verify ballast is not overheating (check ventilation)
• Confirm voltage stability at ballast input

Ballast Shuts Down Automatically

• End-of-lamp-life protection activated - replace lamp
• Thermal protection triggered - improve ventilation, reduce ambient temperature
• Short circuit detected - inspect wiring for damage

Reduced Light Output

• Lamp lumen depreciation - replace aged lamp
• Clean fixture reflector and lens
• Verify input voltage is stable 120V ±10%

Energy Efficiency & Cost Savings

Upgrading from magnetic to GE UltraMax electronic ballasts delivers measurable energy and cost benefits:

• Lower Energy Consumption: Electronic ballasts consume 8-12 watts less than magnetic equivalents
• Reduced HVAC Load: Less heat generation lowers cooling costs in conditioned spaces
• Extended Lamp Life: Low-frequency operation and end-of-life protection maximize lamp operating hours
• Faster ROI: Energy savings typically recover ballast upgrade costs within 2-3 years
• Lower Maintenance: Longer lamp life reduces replacement labor and disposal costs
• Utility Rebate Eligible: Many utility companies offer rebates for electronic ballast retrofits (check local programs)
