I have a 250w HQI with an electronic ballast on my 30 breeder frag tank. It was running for 3-4 days and then yesterday it didn't turn on.

I traced the power from the power strip all the way to the bulb and the bulb is getting power. So I tried two other bulbs and they don't work either????

What else can I try???

Thanks for any info!!!!!!!

That sucks. I didn't wat to hear that. I don't think I can return it.

If I have to replace it what is a good ballast to run a 14K Phoenix bulb?
I want it as blue as possible. So I don't want to overdrive it at all.

I would look in the classified section for dry goods and see what's for sale. One caution...An HQI bulb needs an HQI ballast or a new Electronic Ballast that also works for HQI. I got one new from Hamilton Technology for $200, and it runs all Mogul based 250Watt MH bulbs. That's on the high end...you can probably buy a complete retro for around $145...

Good luck!

Same thing happened to me.. It was the ballast.
