Take a look at bringing your lighting requirements into a whole new light. GE Lighting
 Systems UltraMax™ & NuVation™  electronic ballast technology will provide you with
excellent quality of light combined with cost-saving performance and energy efficiency.
The UltraMax™ & NuVation™ electronic ballast, when used with a PulseArc® High-Output
Metal Halide lamp, is 70% more energy-efficient than the typical standard HID electromagnetic
ballast with standard probe-start metal halide lamp.
The UltraMax™ & NuVation™ electronic ballast system features GE Lighting Systems’
premium optical technology, coupled with superior lumen maintenance and low ballast
losses as compared to magnetic HID ballasts. This translates to significant reductions
 in energy consumption and lower maintenance requirements. These benefits are achieved
 through-fewer fixtures required in new installations or lower wattage lamps used in retrofit
applications in existing locations.
In addition, the UltraMax™ & NuVation™ low-frequency electronic ballast best matches the
 manufacturer’s operating requirements of pulse-start metal halide and has been optimized for
approved operation of GE’s ConstantColor® CMH® lamps. These advantages combined
make the GE Lighting Systems UltraMax™ & NuVation™ ballast system a clear winner when
compared to either alternative HID systems or the latest in T5 or T8 fluorescent lighting.

NuVation DIMMING FEATURE / INSTRUCTIONS
The NuVation™ meets the lamp manufacturers requirements of starting/operating the lamp
 at high wattage for at least 15 minutes before any dimming control can happen.
For continuous operation (24 hr/day) the Nuvation will automatically go into a
full power mode once a day for at least 15 minutes as required by lamp specifications.
NuVation  DIMMING CONTROL
Dimming control is accomplished by connection to the VIOLET + AND GRAY –Wires in the wiring box.
See Diagram A for wiring schematic.
POLARITY MUST BE PROPERLY APPLIED (VIOLET + To control +) AND (GRAY–To control -)
Shorting (example with a switch) the violet and gray wires will cause the Nuvation to operate at
low wattage, removing the short will cause the lamp to operate at full wattage.
External control systems can be used to operate the bi-level function.
A zero (0) to ten (10) volt DC controller can activate the bi-level operation.
This can be either to continuously adjustment lamp wattage 50% to 100%, or one step 50% to 100%.

 

Electronic Ballasts
Electronic Ballasts use solid-state electronic components to start and operate the ballasts.
Electronic ballasts often use IC chips and feedback to implement better controls, and safety
features into ballasts. Electronic ballasts typically operate much more efficiently than similar
Electromagnetic Ballasts. A few other benefits are small size, lightweight, improved lumen maintenance, fault mode protection and better power regulation, which results in better color consistency.

Low Frequency Lamp Operation
GE analysis of internal and competitive HID lamps suggests that the most compatible driving
waveform for an electronic ballast is a Low Frequency Square Wave (L.F.S.W.) with low higher
order harmonic content. L.F.S.W. has been long established as a dependable method of ballasting low Wattage HID lamps with significant industry standards support. Analysis of lamp data has shown that there are limited operating bands between 1 kHz to 200 kHz in which an electronic ballast could operate a lamp wattage family without causing unacceptable arc instability due to Acoustic Resonance. Trend analysis of the A.R. maps show that this range extends well beyond 200 kHz. When the A.R. structure maps are overlaid there is no consistent frequency band, which can be identified as a stable location for ballast operation. There are large variations in the A.R. structure maps between multiple lamp vendors and from lamp type to lamp type or burn position. A.R. may cause visual annoyance, lamp cycling, shorten lamp life, and in extreme cases result in arc tube rupture. Specific matched lamp – ballast high frequency systems can be stable, however they limit the extent that the individual members can be modified for future improvements. Additionally, there is no data on the long-term stability of the A.R. maps due to aging of the lamp. Future re-lamping may also create an unstable system due to changes in lamp arc tube geometry or manufacture.


Lamp performance points to be considered:

Data on Electronic ballast technology has shown that it can greatly improve the lumen maintenance of HID lamps over traditional EM reactor or CWA ballast systems. However, no data are available to support improved lamp performance on High Frequency vs. Low Frequency Square Wave driving waveforms


Conclusions:

GE recommends operation of its high wattage CMH® and PulseArc® QMH HID lamps on electronic ballasts that use a Low Frequency Square Wave output such as the UltraMax® HID ballast, GE-MH-250-400-MAX-208-207 or similar for optimal lamp performance.


High Frequency

GE does not make high frequency HID ballasts due to reasons described in the Low Frequency Lamp Operation section above. However, high frequency operation is applicable for matched lamp ballast systems. Caution must be taken when designing these systems for an application to make sure that the ballast and lamp are compatible to avoid premature lamp failure and safe operation.
