halide not fireing up
 

as the tittle says one of 2 of my halide is not fireing up. Th person who i bought it from says the the hd probloms with the ignitor s im gusssing that it could be the ignitor. Could it be anything else?

I would say it's the ignitor. Does the ballast still 'buzz' when you turn it on? If the previous owner had problems with the ignitor then you had better look into what's causing it to fail.

What brand is your light? Does it go on at all if you play with it a little?

what bulb, what ballast?

Mik what type of ballast is it its not the Aqua Medic ones are they.

yes it sstill dose buzz when I turn it on.
Its a hamilton bulb and the ballast is http://www.jlaquatics.com/phpstore/s...t_ID=pfo-bh252. Yes it gose on for about 45-1 min and just dies.

no it the one i posted above.

I had the same ballasts and had a ton of problems with them trying to run different bulbs. I ended up ordering just the ballast(electronic) from J & L. Then I opened up the cases and replaced them all.
I found that the coil and core ballasts PFO were using were bulb specific and now with the new electronic ballasts I can run them all.

It's a dual ballast? Have you swapped the bulbs around?

I pretty sure your supposed to use an Electronic or HQI ballast to fire Hamilton bulbs

Hamiltons are 1 of the few bulbs that will fire on pretty much any ballast...I ran a couple on some cheap tar ballasts I bought at a hydroponic shop for over a year with no problems.
