The real unique feature we introduced with this fixture was the use of a high voltage, high frequency lamp, while running on a standard consumer voltage.  The spread of the Pro 600 with the industry standard HR96 SE (Single Ended) reflector is about 2.7×4 ft (80×120 cm) at 2 ft distance in overlapping plans for light levels up to 1000 µmol s-1 m-2.

The fixed output, high frequency electronic ballast is designed to drive the Gavita Pro Plus 600 high voltage, high frequency single ended lamp, generating 1150 µmol s-1 of PAR light. This ballast is only suitable for our 400V, high frequency HPS lamps. With a light maintenance of over 96% per 5000 hours you only need to replace it once a year.

The high voltage lamp technology results in a better efficiency of the arc tube: more light for the same power (10-25% more than traditional single ended lamps)! These lamps are best suited for extreme high frequency electronic ballasts, creating a stable arc without acoustic resonance, assuring optimal output and a long lamp life. The smaller arc tube and outer balloon require the lamp to be nitrogen filled instead of vacuum, which prohibits it to be air cooled. Air cooling of the lamp results in lower lamp temperature, which results in sub-optimal light output, up to 15% less than specified. Therefore these lamps are not suitable for direct air cooled fixtures.
