The Lumatek Pro 1000 is a remote electronic ballast that will plug into standard 240V mains supply and power 1000Watt 400Volt Double-Āā€Ended (K12x30s)HPS grow lamps. This ballast has a boot-Āā€laced (exposed wires) output (lamp) cable for direct connection to a reflector with a ā€K12x30sā€™ Double-Āā€ Ended mogul socket such as the ā€Lumatek 1000DE Reflectorā€™. It can be easily integrated into your existing grow room; simply replace your ballast/reflector/lamp with the Lumatek Pro 1000 bundle and you will instantly achieve more useable grow light! More light = more yield! The Lumatek Pro 1000 has been specifically designed to help the hobby-Āā€grower access the benefits of using electronics to control and power professional 400Volt horticultural lamps. These lamps are superior to the 240Volt lamps traditionally used in the hobby hydroponics and indoor garden markets due to their increased efficiency and greater PAR spectrum output. Photosynthetic Active Radiation (PAR) refers to the part of the light spectrum that plants actually use to photosynthesize and convert energy to grow. Using microprocessor and software controlled electronics, the Lumatek Pro 1000 is an ultra-Āā€high frequency ballast operating at 125KHz (125,000 cycles per second). A conventional magnetic ballast operates at 50Hz (50 cycles per second), making much less light available to the plant. You can see the difference in quality of light yourself using the video camera on your phone; try filming a light powered by a magnetic ballast (shows strobe flicker) and then the Lumatek (shows solid light). This increased efficacy means less power is lost from the power supply to the lamp. The high frequency output results in low power loss at the cathodes in addition to better overall power management. Key Features Voltage regulator precision: microprocessor and software controlled electronics monitor and sense the lamp and it's current state of degradation ensuring the lamp receives the precise voltage necessary to achieve optimum PAR spectrum output (the actual part of light that plants use to photosynthesize) regardless of mains supply voltage fluctuations. Soft Start: when ballast is switched on, the software controlled electronics manage and control inrush current so as to prevent initial surge tripping circuit-Āā€breakers and protect and enhance lamp-Āā€ life. The ballast will bring the lamp to full brightness within three minutes. Sequential switching: the ballast detects other ballasts on the same ring circuit. When used in an automated system, the ballasts will start independently rather than simultaneously so as to manage the electrical load and prevent circuit-Āā€breakers from tripping. Soft dim: when the ballast output power is changed, the regulator software controls the change in power so that it is gradual, thus reducing stress on the lamp and improving lamp-Āā€life. Circuit protection and Autoā€restart: the ballast will detect power surges, short circuits, circuit-Āā€ interruption, over-Āā€heating and switch off to prevent any damage to the lamp or the ballast. To protect against hot re-Āā€strike, the ballast will monitor and sense when the lamp is ready to be reignited and will then restart automatically. End of lamp-Ālife: the ballast will monitor and sense when the lamp is coming to the end of it's useable life and will not attempt to ignite it thus avoiding negative spectral and colour anomalies. No noise: the Lumatek ballast is completely silent and produces no vibrations due to using the graduated fin design of the case as a heat sink which negates the need for an internal fan. Less heat: the ballast is extremely efficient and very little energy is lost as waste heat. Lightweight: the ballast is compact and light, weighing 5Kg making it easy to position and mount.
