De Lumenking Grow light fixtures are available in a 300 watt to 600 watt and a 600Watt to 1000Watt version. The bulbs of the two different fixtures are not inter changable since the 1000watt version uses a 1000w Double-ended bulb as opposed to the 600watt buld that has a screw fitting.
The lumenking 1000W ballasts can be controlled through what is called a master controller. With use of the master controller you are able to controll two separate groups of ballast from one central controller. Each group can house up to 120 ballasts. With the master controller you will be able to controll things like a day/night cycle, switch the ballast groups on and off or dim each group separate. You do not realley need the master controller if you own one or maybe two ballasts unless you want to be able to controll these from a central hub. The master controller becomes an absolute must for larger rooms or greenhouses with large amounts of ballasts.
There is a maximum distance to where you place the ballasts however you need to keep in mind that you can use a max. cable length of 120 meters of the master controller. All this is what makes our fixtures suitable for starters as well as larger commercial farmers and growers.
The Lumenking master controller comes with all the necessary part like sensors, cables and powersupply.
NOTE: The Lumenking Grow Light Fixtures come INCLUDING the HPS bulb. However the master controller is a SEPARATE PRODUCT and will have to be bought as seperate product.
