I have to replace bout 6 old magnetic t12's ballast in 3 four t12's light bulb fixture. I was just gonna replace them for the electronic t12 ones and put new bulbs. i called my supplier to give the customer an estimate, my supplier told me i'd be better off just getting 3 four light bulbs t8's ballast, and rewire them. It'll save me about $40.00. In the past i,ve always replaced the magnetic t12 ballast with the electronic one, but in this case i think the savings justify the t8 ballast upgrade. i already bid the job, so this will mean more profit as well.
-Will the t8's light bulbs fit the old t12's sockets?
- t8's take the power to the socket while t12's take power to ballast
right? if i remember correctly. . .
- Which ones you all trust better t8's or t12's?
The only issue i see here too, is that they have about 4 more fixtures that they work fine and they don't want to upgrade at these moment, so they may confuse when is time to buy bulbs, you know?
Thanks a lot.
