| Uni-Form pulse start lamps provide superior performance compared to traditional metal halide lamps. The specific benefits are higher efficacy, better colour 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 moulds each arc tube for improved colour uniformity.
High Performance Design
Formed body arc tube advantages
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 colour uniformity.
Higher Fill Pressure
Our formed-body design supports a higher fill gas level that helps to reduce wall blackening caused by tungsten sputtering from the electrodes at each start.
High Performance Results
Superior Lamp 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. Using Venture’s 15,000 hour Uni-Form pulse start lamps (150, 175, 200 or 250 W) means re-lamping less often - labour savings pay for lamp replacement over system life.
Colour Uniformity
Lamp-to-lamp colour variations occur due to arc tube temperature differences and poor power control. 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.
Faster Warm-Up/Restrike
Combining our exclusive formed-body arc tube and ignitor starting, with our low current crest factor ballasts, provides faster initial warm-up
and hot restrike up to 60% less time.
More Optically Precise
Our patented weldless arc tube mount precisely centres the arc. It outlasts welded mounts, staying more consistently on spec.
More Light for Less Energy
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.
