This kit features: The Phantom II Digital Ballast takes the reliability and engineering superiority of the original Phantom ballast and adds industry leading Smart Alert Technology, setting a new standard for excellence and functionality. The Phantom II is TOTALLY silent, energy efficient, reliable, and lightweight. Smart Alert Technology utilizes a 32MHz fully integrated microprocessor to keep your setup running smoothly. The Phantom has built-in hot re-strike programming to protect the lamp and ballast in the event of the ballast turning off unexpectedly. The ballast will not attempt to restart a hot lamp for at least 15 minutes. Phantom II features Smart Alert Technology High-precision microprocessor control High efficiency Ignition voltage control Four way dimming feature 60%, 75%, 100% and Super Intelligent lamp ignition and power control LED indicators Intelligent lamp detection End of life lamp protection and indication Current sense intelligent startup Precision thermal controls FCC certified for minimal electrical interference Digilux High Pressure Sodium bulbs are favored by growers because of the wide color spectrum and efficiency. They are engineered for use in digital ballasts and feature enhanced red and orange spectrums, better color uniformity, longer bulb life, and less lumen depreciation. Digilux bulbs can be used in both vertical and horizontal fixtures. Digilux lamps offer superior performance compared to traditional and HPS lamps. Digilux HPS bulbs deliver 25% more energy in the red and orange spectrums.
