    re wiring ballast in t-12

    anyone , can you give some advise on putting a new ballast in a t-12, 2 foot 2 bulb fixture?
    having trouble finding one like it again.
    this one has a reflector( just white) but its more than enough light for my low light paphs.
    so i would like to salvage the unit if at all possible.
    the thing is riveted closed so im thinking i could drill out the rivets , and replace them with simple sheet metal screws , I just dont know where to start in finding another ballast that will work with this unit
    av8tor1 ?
    swords ?
    you guys out there?

    Most ballasts have the info about how many bulbs and how much watt on them, often a wiring diagram too.
    Afaik anything else you need to look up is what type you want, magnetic, electronic, electronic cold start, and some other ones i dont know.
    If you get any with right wattage and works with 2 bulbs it should work.

    Hey Jimmy, as cheap as 2 tier T12 fixtures are these days it may be more economical to get a brand new one then to fix it. That is unless you're wanting to have some fun taking things apart

    Btw, magnetic ballasts might mess up digital timers.
    I cant get mine to work with any of them.

    not much to it, guess ill have to keep looking for a replacement unit, seems the ballast is part of the end piece which holds the bulbs, any ideas where I could get another 2 bulb 2 foot t-12 similar to this , i kinda need a lower watt fixture , as the paphs under this light need some light but very little, all im finding are t-5 and t-8 fixtures and they produce way too much light.
    going to e-bay and amazon right now to seee what I can see

    can't you attach a regular ballast in the middle between the bulbs? , or you could even put the ballast somewere totally different, it does not have to be inside the fixture.
