Those shop lights use Halogen bulbs, not high pressure sodium bulbs.
Dutch Pimp Reviewed by Dutch Pimp 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
