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
Skihigh Reviewed by Skihigh on . HPS keeps blowing So, I'm using 500 watt HPS shop light for my veg setup. The problem is the light bulb keeps blowing. This is the third time during the last 2 weeks or so, and the second time in 2 days. I was wondering if anyone has experience with using these lights and if they have run into the same problem. I almost feel like I've got some kind of faulty housing that is somehow causing the bulbs to burn out. The grow I did before this I used the same type of light, and I don't recall ever having to replace Rating: 5
