I am switching from T12 shop lights to T8 shoplights. Still have several
T12 fixtures. I bought a lot of T8 bulbs but I am out of T12 bulbs.

Can I use T8 bulbs in fixtures that previously used T12 bulbs? Of course,
T8 bulbs are 32 watt and T12 are 40W. Will the T8 bulbs kill the ballasts
in my remaining T12 fixtures? Will the old T12 ballasts kill my new T8
bulbs?

Thanks for any insight

T12's are 34 watt. They may work but I wouldn't recommend doing it. Just
replace the ballasts with T8 type
