UNI-FORM®
PULSE START LAMP TECHNOLOGY
Uni-Form pulse start lamps provide superior performance compared
to traditional metal halide lamps. The specific benefits are higher
efficacy, better color uniformity, faster warm-up, improved lumen
maintenance and longer life. It all takes place in Venture’s
revolutionary formed-body arc tube.
One key to superior
lamp performance is heat management. In traditional arc tubes, uneven
heating prevented optimum arc enhancement. Venture created an exclusive,
tipless formed-body arc tube, sculpted to follow the actual curve
of the arc stream. The shape creates a more uniform temperature
profile. Higher temperatures draw more halides into the stream,
resulting in more light generated. Our unique sculpting process
also molds each arc tube for improved color uniformity.

HIGH PERFORMANCE
DESIGN
Formed-Body
Arc Tube
The
shape of our formed-body quartz arc tube follows the actual curve
of the arc stream, preventing uneven temperatures in the arc tube
surface. This significantly improved thermal performance allows
more halides to be pulled into the arc and emit more light.
Reduced Pinch
Seals
The large
pinch fins on traditional metal halide arc tubes radiate heat. Replacing
them reduces the quartz mass in the arc tube and helps in producing
a more uniform thermal profile which results in greater lamp efficacy.
Tipless Arc
Tube
The exhaust
tip on traditional arc tubes creates a cold spot which degrades
arc performance. Our exclusive tipless design ensures a totally
uniform surface to the arc tube shape, improving efficacy and color
uniformity.
High Voltage
Pulse Ignition
High voltage
pulse ignitor starting eliminates the starter electrode, bi-metal
switch and resistor of standard probe start lamps. It also provides
quicker breakdown of gases; so starting (cold and hot) is faster.
Higher Fill
Pressure
Our formed-body
design and pulse ignition support a higher fill gas level that helps
to reduce wall blackening caused by tungsten sputtering from the
electrodes at each start.
Weldless
Arc Tube Mount
Venture’s
nearly unbreakable, patented weldless construction is stronger than
traditional welded mounts.
Opti-Wave
Ballasts
The lower current crest factor in the electrical output of
our ballasts improves lamp lumen maintenance. Ballast energy losses
are reduced by as much as 50% compared to standard CWA ballasts.

SYSTEM SOLUTIONS
Venture’s pulse start system technology, actualized in Uni-Form
lamps and Opti-Wave™ ballasts, represents advancement as important
as the invention of the metal halide lamp. Every change in our arc
tube design, lamp construction and ballast enhances overall system
performance. This metal halide focus allows us to offer a vast array
of integrated packages, providing optimum lighting efficacy and
quality for virtually any application.
HIGH
PERFORMANCE RESULTS
Superior
Lumen Maintenance
Uni-Form
pulse start system lumen output does not decay as rapidly over life
as traditional metal halide. Mean lumens improve dramatically, up
to 50% higher, with our lamps operating on our Opti-Wave low current
crest factor ballasts.
Longer Life
Our Uni-Form pulse start system
offers up to 50% longer lamp life along with improved lumen maintenance.
This directly benefits end-users by reducing lifetime operating
costs. While 50% of standard metal halide lamps survive at the end
of their rated life, 70% of Uni-Form pulse start lamps will still
be operating.

Color Uniformity
Lamp-to-lamp
color variations occur due to arc tube temperature differences and
poor power regulation. Venture minimizes variation through consistent
thermal characteristics in every arc tube and better power control
from our ballasts.
Better Cold
Starting
Uni-Form
technology offers more reliable starting at extreme temperatures,
down to -40°C (-40°F). It’s perfect for winter weather
or warehouse freezer conditions.

More Optically
Precise
Our patented weldless arc tube mount precisely centers the arc.
It outlasts welded mounts, staying more consistently on spec.
Improved
Lamp Power Control
The well regulated output power of our ballasts improves color uniformity
and lumen maintenance.
Quieter Operation
Venture’s Opti-Wave ballasts run at least 25% quieter than
comparable CWA ballasts due to non-saturation of the core.
Opti-Wave
Ballast For Improved Performance
The Venture® Opti-Wave family sets the Gold Standard in ballast
performance with an optimized current wave form. To maximize your
pulse start metal halide system, specify Quint-Volt™ or power
saving 277V ballasts.

THE BOTTOM
LINE IS MORE LIGHT FOR LESS ENERGY.
Uni-Form® pulse start technology will exceed your expectations.
More light for less energy makes Uni-Form pulse start the most logical
lighting choice for designers and corporate energy managers seeking
to drastically cut power bills. Compared to standard metal halide,
Venture’s revolutionary system offers up to 50% improvement
in system mean lumens per watt. In practical applications, the higher
efficiency translates into a savings of more than 100 watts per
luminaire! And that savings comes while still producing the same,
or more, high quality light.
