Hi all
 
My 30 year old 
8' t-12 (single pin) garage fixtures are slowly dying...(4 total double tube)
the old t-12s are hard to find and expensive (16-20 bucks a tube)
 
Want to change to led... lots of options  - 8' 
led tubes are expensive too ... 
 
I was gifted a box of 20 
4' bi-pin bulbs that work with a ballast...(heat sink)
 
option 1 
if I use these I'd 
have to change all the tombstones to bi-pin and figure out the
shunted vs non shunted type...  AND find the 8' to 4' fixture conversion kits 
(adding the middle tombstones
 
option 2
8' type a led single pin tubes (about the same price as 8' fluorescent) and use 
a ballast
not great reviews when shipped...
 
option 3
 
replace all the crap with the internet specials  linkable stick lights and hope 
they work
 
comments on options ????
 
questions... when using the ballast type plug and plays... aren't I using more electricity using the ballast 
and heating it up... is there any savings here ???
 
 
please educate the old dummy on best (least expensive) options
