There ain't gonna be a ballast in that light fixture....It's a halogen shop light .....Maybe not the best light to use mainly because of the color rendering.....Halogens put out around 10,000 kelvin....Too much or to little usable color for growing....(You need around 2,600 to 6,500 kelvin) And they are way too hot to use very close to the plants.
If you touch the glass halogen bulbs with your hands,the oils from your skin can rub off and cause hot spots on the bulb possibly causing premature burn out.Hope this helps some...........J
