Metal halide lights give off an intense, bluish-white light that plants respond to with healthy, vigorous growth. Plants will be stocky and strong, with dense green foliage. Metal halide is the light of choice for indoor plant gardeners during the vegetative.
High pressure sodium lights for the flowering stage. High pressure sodium light bulbs emit a white light concentrated in the orange/red spectrum. The orange/red sector of the spectrum enhances plants' reproductive processes. High pressure sodium simulates outside autumn light and plants respond by producing larger harvests of high quality fruits, vegetables and flowers. High pressure sodium, then, is used by indoor gardeners during the flowering and fruiting stage of plant life.
The quantum dimmable ballast brings quality, efficiency, and high intensity illumination to your garden. With a power factor of 99.9%a highly stable output frequencythe quantum dimmable ballast lets you run your lamps at the strength you need allowing you to control your light spread. Rigorously engineered, it features a resin cased circuit board with a sealed bearing fan so it will run cooler than any other ballast and it's been tested to withstand the extreme atmospheric conditions of virtually any growing environment.
The quantum dimmable ballast is silent, generator-ready, efficient, and cool-runningthis is one cool ballast. Run at 100%, 75% or 50% power (400w runs at 100% and 75%). Strikes both metal halide and high pressure sodium bulbs. Accepts 120v/240v with no wiring needed (both cords included); 208v-configurable with electrician assistance. Accepts 50 hz to 60 hz with no extra wiring needed.Runs 15% cooler than other digital ballasts on the market. Has a continuous power factor of 99%. The most stable output frequency of any ballast. Higher lumen output than magnetic ballasts. Can run efficiently on generators without flickering. Resin sealed circuit board for high humidity installations. Can easily be used in conjunction with lighting controllers and flip boxes.
