New MH bulb not working - help

[CMOS]

Howdy All,

I just got a new Ushio 175W MH bulb as it was time for a routine replacement. The darn thing begins to fire when turned on but after about 30 seconds, it craps out completely.

Thoughts?

Bulb? Problem with the charging circuit?

Pulse or Probe start MH? You may have bought the wrong type. There are different ways that a MH fires.

Wrong type of bulb? It appears to be the correct type, as in the bulb style I see no differences in spec's for ballasts.

Could this be a degraded capacitor in my ballast? FYI -the "old" bulb fires and burns just fine.

Your cap could be old and not up to being able to fire the new bulb, its possible. You have a electronic ballast or magnetic?

Not sure - the components in the ballast consist of only a large transformer and a single large capacitor.

The Ushio bulb I bought states this: "*Requires HQI ballast, electronic ballast or pulse start ballasts to work properly." (in VERY tiny letters)

I take it this will not work? What is HQI?

Ouch. Wrong bulb. HQI is the small double ended bulbs.

I believe HQI refers to the type of ballast.....

I don't think so.

Yes, the HQI Ballast runs an HQI Double Ended Bulb. My bad for the reply I made earlier, it was not entirely true. It is also a HQI Ballast. My bad.

No badness here my friend. I'm still learning, so there are no "bads" to be had.

I bought the "wrong" bulb from Marine Depot, who exchanged it for another brand with no-questions-asked. I should see the new bulb hit my doorstep in about 4 more days. Hopefully all will be well and [cough] bright at that time.

Right on, sounds like a plan to me.

Hey guys...this has been very educational for me, so thanks!

I've never run MH, but who knows, I might want to someday.

My research revealed that for a deep tank (mine is 24" deep) MH is the way to go for good depth penetration. At least I think so.

Yup, pretty much. LED are the other choice, but won't penetrate as well as a 400w halide will that deep.

You know, I should add to the above post that 400w Halides are good for depth, and LED using 5w LED's will go that depth also.
