The ballast runs perfectly, fires up and runs smoothly.

I get that initial spark of electricity through the bulb trying to fire it up but it won't fire. I thought it could be the ignitor my self but it's brand new ...

I cannot get a bulb at the hydrostore because they're out until friday. I have contacted a friend locally to get an old 400 HPS and MH bulb he has and try those. Hopefully with some success, if not I will be using an old 400w magnetic ballast while I return this one and buy something better.

Joel Reviewed by Joel on . Bad HPS Bulb? Help!! Hey guys, yesterday and today Ive been having issues with my light. Yesterday upon plug in she did not fire, unplugged waited 5 seconds plugged in and bam lit up. This morning, nothing at all. When I took the light out and plugged it in, I can see the electricity spark up the bottom of the bulb and then off so it's not firing it. The inside coil looks like its black and I'm wondering if it's faulty. Please refer to pics. The red arrow indicates where I can see electricity come up and Rating: 5
