Electronic Ballasts
A range of GE electronic ballasts have been introduced to complement the 20, 35, 70 and 150W ConstantColor™
Ceramic Metal Halide lamps
Power controlled electronic ballasts suitable for operation of Ceramic Metal Halide lamps are available from various gear
manufacturers.
Advantages are:
• Good regulation against supply voltage variation
• Improved lamp colour consistency
• Elimination of lamp flicker
• Reduced weight of control gear
• Reduced electrical power losses
• Ballast noise reduced/eliminated
• Single piece compact unit
• Reduced wiring complexity in the luminaire
Features
• Integral version with open terminals for embodiment into luminaire
• Remote version with terminal cover and cable strain relief for location outside the luminaire
• 50,000 hours service life under the specified conditions
• Reduced power consumption compared to electromagnetic circuits
• Reduced component count and simplified wiring compared to electromagnetic circuits
• Rapid and controlled power run-up
• Lamp life maximised by square-wave current and constant lamp power
• Excellent lamp colour stability throughout life
• Automatic lamp failure shut-down
• Timed restart after mains voltage interruption
• Immune to mains voltage variations

* If a hot lamp or no lamp is detected the ballast will attempt to start the lamp after one minute, if not successful further attempts are made up to a maximum
of 4 times in 5 minute cycles, then if not successful the ballast will shut-down. The ballast is reset automatically by a supply interruption.
** Typical value if cable capacitance is below the specifi ed limit
