My shop has six 8' T12 fluorescent light fixtures, per bay. Every year when it turns off cold I am replacing bulbs and or ballasts, it never fails. This year I got tired of it and started looking for something different, maybe T8 or T5 HO, something I could get years of service out of. Quickly I found a change out wasn't cheap so I found some LED replacements. The ballast is removed and the sockets are wired directly to the 120.
I have to say I am quite impressed. Tried to take pictures but you really couldn't tell anything but the light meter on my phone shows the LEDs are 2.5 to 3 times brighter than the T12s.
