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

Walter
