Yep, it is karked, tried two different bulbs and no luck ... any one recommend Radion Gen2 or AI Vega for my tank?

Did you get it fixed? When my JBJ ballast quit it was just the switch. Easy fix, I bypassed the switch.

I don't know enough about electronics, tried to get an electrical guy to look at it but no joy, I ended up buying an LED, guess I should have tried a little harder ... thanks for the suggestion ...

It appears to be a coil/capacitor magnetic ballast, not electronic. In most cases with these, it's the capacitor or ignitor (if it has one) that will fail. Either should be simple to replace, but you need to get the numbers/specs of the capacitor in order to find a compatible replacement or original part. Careful when handling a capacitor, particularly a large one, they can store a charge for a long time. Short the terminals with a screwdriver or something similar with an insulated handle to discharge it. If you put your fingers across the terminals inadvertantly, you could get a nasty zap.

I see that you've purchased an LED fixture now, but it may still be worth resurrecting the Halide. A couple of links to pages with pdf version of HID Lighting Ballast Pocket Guide follow. This has detailed info on most types of ballast & includes a troubleshooting section at the end.

& a link to the manual for your light, I think...

All the right experience
 

Take a trip down to the Incredigrow store off Macleod by cheesecake cafe. These hydroponic horticulture specialists work with mh ballasts for a living they can give you options.

Make a phone call
 

You should pick up the phone and call jbj lighting tech support and discuss the problem and fixes thoroughly with them to get as much information out of them as possible.

Maybe they can just send the part you need.
