I have several 8 and 4 foot lights (all T12) in my garage that I am considering swapping over to LED. Two lights have a bad ballast, one has a noisy ballast and about 6 of the bulbs are turning black at the ends. Since the T12 lights are being phased out of production the bulbs and ballasts are getting expensive. Especially the 8 foot bulbs. My original plan was to switch everything to T8 fixtures over time as needed. Although those are also going to be phased out also at least I know how long to expect them to last. Now LEDs are popular and getting cheaper so I was wondering if anyone has any experience with them. My shop ceilings are about 9 ½ feet and everything is painted so I just want to know how "bright" they are compared to fluorescent (cool white) lights and if anyone has had bad luck with them not lasting as long as they say. Has anyone had a bad experience with them? I have a LED drop light but really prefer the old standby 100 watt bulb (until I am working under a dash. I have switched some incandescent bulbs inside the house to LED and so far they are outlasting the standard socket CFLR bulbs that were supposed to be better than the incandescent bulbs. The CFLR bulbs suck in my opinion. I know how long new T8 bulbs/ballasts will last but using less power would be a plus also.
